Prologue Welcome Welcome to Ge? ing Started with Ubuntu, an introductory guide wri? en to help new users get started with Ubuntu.
Our goal is to cover the basics of Ubuntu (such as installation and working with the desktop) as well as hardware and so? ware management, working with the command line, and security. We designed this guide to be simple to follow, with step-by-step instructions and plenty of screenshots, allowing you to discover the potential of your new Ubuntu system. Canonical releases new versions of Ubuntu every six months; every fourth release is a so-called long-term support (??? ) version. Ubuntu ??.?? (code-named Raring Ringtail) is considered a regular release and is supported by Canonical with patches and upgrades for nine months. e most recent ??? version is Ubuntu ??.?? (Precise Pangolin), and has support for ? ve years (until April ???? ). Whenever a new version of Ubuntu is released, we will incorporate updates and changes into our guide, and make a new version available at http://www. ubuntu-manual. org. Ge? ing Started with Ubuntu ??.?? is not intended to be a comprehensive Ubuntu instruction manual. It is more like a quick-start guide that will get you doing the things you need to do with your computer quickly and easily, without ge? ing bogged down with technical details. As with prior versions, Ubuntu ??.?? ncorporates many new and improved features, including new icons (some dynamic), more Appearance options, improved Dash Preview design, smart scopes, to name just a few. With the help of this guide, it should not take long before new users get used to the Unity desktop environment. Unity includes the Starter, the Dash, the ??? , indicators, and a noti? cation system (??? ). All these features will be explained in this guide. For more detailed information on any aspect of the Ubuntu desktop, see the “Ubuntu Desktop Guide,” which can be obtained in any of the following ways: ? n the Dash, type help. ? in the desktop menu bar, click Help ? Ubuntu Help. ? go to https://help. ubuntu. com, Ubuntu ??.?? ? Ubuntu Desktop Help. ?ere are also many excellent resources available on the Internet. For example, on https://help. ubuntu. com you will ? nd documentation on installing and using Ubuntu. At the Ubuntu Forums (http://ubuntuforums. org) and Ask Ubuntu (http://askubuntu. com), you will ? nd answers to many Ubuntu-related questions. If something isn’t covered in this manual, chances are you will ? nd the information you are looking for in one of those locations.
We will try our best to include links to more detailed help wherever we can. Ubuntu Philosophy Each Ubuntu release has a version number that consists of the year and month number of the release, and an alliterative code name using an adjective and an animal. Code names are in consecutive alphabetic order, allowing a quick determination of which release is newer. As of Ubuntu 11. 04 the desktop interface signi? cantly di? ers from the previous releases because Unity was introduced as the default GUI. You can ? nd more information about Ubuntu’s online and system documentation in Chapter 8: Learning More. e term “Ubuntu” is a traditional African concept originating from the Bantu languages of southern Africa. It can be described as a way of connecting with others—living in a global community where your actions a? ect all of humanity. Ubuntu is more than just an operating system: it is People sometimes wonder how to pronounce Ubuntu. Each u is pronounced the same as in the word put except for the last u which is pronounced the same as in the word due. ? ??????? ??????? ???? ?????? ??.?? a community of people coming together voluntarily to collaborate on an international so? are project that aims to deliver the best possible user experience. The Ubuntu Promise ? Ubuntu will always be free of charge, along with its regular enterprise releases and security updates. ? Ubuntu comes with full commercial support from Canonical and hundreds of companies from across the world. ? Ubuntu provides the best translations and accessibility features that the free so? ware community has to o? er. ? Ubuntu’s core applications are all free and open source. We want you to use free and open source so? ware, improve it, and pass it on. A brief history of Ubuntu Ubuntu was conceived in ???? y Mark Shu? leworth, a successful South African entrepreneur, and his company Canonical. Shu? leworth recognized the power of Linux and open source, but was also aware of weaknesses that prevented mainstream use. Shu? leworth set out with clear intentions to address these weaknesses and create a system that was easy to use, completely free (see Chapter ? : Learning More for the complete de? nition of “free”), and could compete with other mainstream operating systems. With the Debian system as a base, Shu? leworth began to build Ubuntu. Using his own funds at ? rst, installation ?? were pressed and shipped worldwide at no cost to the recipients. Ubuntu spread quickly, its community grew rapidly, and soon Ubuntu became the most popular Linux distribution available. With more people working on the project than ever before, its core features and hardware support continue to improve, and Ubuntu has gained the a? ention of large organizations worldwide. While large organizations o? en ? nd it useful to pay for support services, Shu? leworth has promised that the Ubuntu desktop operating system will always be free. Ubuntu is installed on an estimated ? % of the world’s computers. is equates to tens of millions of users worldwide, and is growing each year. As there is no compulsory registration, the percentage of Ubuntu users should be treated as an estimate. What is Linux? Canonical is the company that provides ? nancial and technical support for Ubuntu. It has employees based around the world who work on developing and improving the operating system, as well as reviewing work submitted by volunteer contributors. To learn more about Canonical, go to http://www. canonical. com. Debian is the Linux operating system that Ubuntu is based upon. For more information visit http://www. debian. org/.
For information on Ubuntu Server Edition, and how you can use it in your company, visit http:// www. ubuntu. com/business/server/overview. Ubuntu is built on the foundation of Linux, which is a member of the Unix family. Unix is one of the oldest types of operating systems, and together with Linux has provided reliability and security for professional applications for almost half a century. Many servers around the world that store data for popular websites (such as YouTube and Google) run some variant of Linux or Unix. ?e popular Android system for smartphones is a Linux variant; modern in-car computers usually run on Linux.
Even the Mac ?? ? is based on Unix. ?e Linux kernel is best described as the core—almost the brain—of the Ubuntu operating system. ?e Linux kernel is the controller of the operating system; it is responsible for allocating memory and processor time. It can also be thought of as the program which manages any and all applications on the computer itself. ???????? ? Linux was designed from the ground up with security and hardware compatibility in mind, and is currently one of the most popular Unix-based operating systems. One of the bene? ts of Linux is that it is incredibly ? exible and can be con? ured to run on almost any device—from the smallest micro-computers and cellphones to the largest super-computers. Unix was entirely command line-based until graphical user interfaces (??? s) emerged in ???? (in comparison, Apple came out with Mac ?? ten years later, and Microso? released Windows ?.? in ???? ). ?e early ??? s were di? cult to con? gure, clunky, and generally only used by seasoned computer programmers. In the past decade, however, graphical user interfaces have grown in usability, reliability, and appearance. Ubuntu is just one of many di? erent Linux distributions.
Is Ubuntu right for you? While modern graphical desktop environments have generally replaced early command line interfaces, the command line can still be a quick and e? cient way of performing many tasks. See Chapter 6: Advanced Topics for more information, and Chapter 2: The Ubuntu Desktop to learn more about GNOME and other desktop environments. To learn more about Linux distributions, see Chapter 8: Learning More. New users to Ubuntu may ? nd that it takes some time to feel comfortable when trying a new operating system. You will no doubt notice many similarities to both Microso? Windows and Mac ?? as well as some differences. Users coming from Mac ?? ? are more likely to notice similarities due to the fact that both Mac ?? ? and Ubuntu originated from Unix. ?e Unity shell, which is the default in Ubuntu, is a completely new concept, which needs some exploring to get used to it. See Chapter ? : ? e Ubuntu Desktop for more information about the Unity shell. Before you decide whether or not Ubuntu is right for you, we suggest giving yourself some time to grow accustomed to the way things are done in Ubuntu. You should expect to ? nd that some things are di? erent from what you are used to.
We also suggest taking the following into account: Ubuntu is community based. ?at is, Ubuntu is developed, wri? en, and maintained by the community. Because of this, support is probably not available at your local computer store. Fortunately, the Ubuntu community is here to help. ?ere are many articles, guides, and manuals available, as well as users on various Internet forums and Internet Relay Chat (??? ) rooms that are willing to assist beginners. Additionally, near the end of this guide, we include a troubleshooting chapter: Chapter ? : Troubleshooting. Many applications designed for Microso?
Windows or Mac ?? ? will not run on Ubuntu. For the vast majority of everyday computing tasks, you will ? nd suitable alternative applications available in Ubuntu. However, many professional applications (such as the Adobe Creative Suite) are not developed to work with Ubuntu. If you rely on commercial so? ware that is not compatible with Ubuntu, yet still want to give Ubuntu a try, you may want to consider dual-booting. Alternatively, some applications developed for Windows will work in Ubuntu with a program called Wine. For more information on Wine, go to http://www. winehq. org.
Many commercial games will not run on Ubuntu. If you are a heavy gamer, then Ubuntu may not be for you. Game developers usually design games for the largest market. Since Ubuntu’s market share is not as substantial as Microso? ’s Windows or Apple’s Mac ?? ?, fewer game developers allocate resources towards making their games compatible with Linux. If you just enjoy a game every now and then, there are many high quality games that can be easily installed through the Ubuntu So? ware Center. To learn more about dual-booting (running Ubuntu side-by-side with another operating system), see Chapter 1: Installation.
See Chapter 5: Software Management to learn more about Ubuntu Software Center. ? ??????? ??????? ???? ?????? ??.?? Contact details Many people have contributed their time to this project.

Many companies (such as Dell and System76) sell computers with Ubuntu preinstalled. If you already have Ubuntu installed on your computer, feel free to skip to Chapter 2: The Ubuntu Desktop. Getting Ubuntu Before you can get started with Ubuntu, you will need to obtain a copy of the Ubuntu installation image for ??? or ???. Some options for doing this are outlined below. Minimum system requirements Ubuntu runs well on most computer systems. If you are unsure whether it will work on your computer, the Live ??? is a great way to test things out ? rst. Below is a list of hardware speci? ations that your computer should meet as a minimum requirement. ? ? ? ? ? ? ? GHz x?? processor (Pentium ? or be? er) ? ?? of system memory (??? ) ? ?? of disk space (at least ?? ?? is recommended) Video support capable of ???????? resolution Audio support An Internet connection (highly recommended, but not required) The majority of computers in use today will meet the requirements listed here; however, refer to your computer documentation or manufacturer’s website for more information. Downloading Ubuntu ?e easiest and most common method for ge? ing Ubuntu is to download the Ubuntu ??? mage directly from http://www. ubuntu. com/download. Choose how you will install Ubuntu: ? Download and install ? Try it from a ??? or ??? stick Download and Install / Try it from a DVD or USB stick For the Download and install, or Try it from a ??? or ??? stick options, select whether you require the ?? -bit or ?? -bit version (?? -bit is recommended for most users), then click “Start download. ” 32-bit versus 64-bit Ubuntu and its derivatives are available in two versions: ?? -bit and ?? -bit. ?is di? erence refers to the way computers process information. Computers capable of running ?? -bit so? are are able to process more information than computers running ?? -bit so? ware; however, ?? -bit systems require more memory in order to do this. Nevertheless, these computers gain performance enhancements by running ?? -bit so? ware. ? If your computer has a ?? -bit processor, install the ?? -bit version. ? If your computer is older, a netbook, or you do not know the type of processor in the computer, install the ?? -bit version. If your computer has a ?? -bit processor, select the “?? -bit” option before you click “Start download. ” 32-bit and 64-bit are types of processor architectures.
Most new desktop computers have a 64-bit capable processor. ?? ??????? ??????? ???? ?????? ??.?? Downloading Ubuntu as a torrent When a new version of Ubuntu is released, the download servers can get “clogged” as large numbers of people try to download or upgrade Ubuntu at the same time. If you are familiar with using torrents, you can download the torrent ? le by clicking “Alternative downloads,” and then “BitTorrent download. ” Downloading via torrent may improve your download speed, and will also be help to spread Ubuntu to other users worldwide. Burning the DVD image Torrents are a way of sharing ? es and information around the Internet via peer-to-peer ? le sharing. A ? le with the . torrent extension is made available to users, which is then opened with a compatible program such as uTorrent, Deluge, or Transmission. These programs download parts of the ? le from other people all around the world. Once your download is complete, you will be le? with a ? le called ubuntu??.?? -desktop-i???. iso or similar (i??? here in the ? lename refers to the ?? -bit version. If you downloaded the ?? -bit version, the ? lename contains amd?? instead). ?is ? le is a ??? image—a snapshot of the contents of a ??? which you will need to burn to a ???. Creating a bootable USB drive While the 64-bit version of Ubuntu is referred to as the “AMD64” version, it will work on Intel, AMD, and other compatible 64-bit processors. If your ?? is able to boot from a ??? stick, you may prefer to use a ??? memory stick instead of burning a ???. Scroll down to “Burn your ??? or create a ??? drive,” select ??? or ??? stick, choose the ?? you are using to create the ??? drive, and then click Show me how. If you select the “??? Stick” option, your installation will be running from the ??? memory stick. In this case, references to Live ??? will refer to the ??? memory stick. Trying out Ubuntu ?e Ubuntu ??? and ??? stick function not only as installation media, but also allow you to test Ubuntu without making any permanent changes to your computer by running the entire operating system from the ??? or ??? stick. Your computer reads information from a ??? at a much slower speed than it can read information o? of a hard drive. Running Ubuntu from the Live ??? also occupies a large portion of your computer’s memory, which would usually be available for applications to access when Ubuntu is running from your hard drive. e Live ??? /??? experience will therefore feel slightly slower than it does when Ubuntu is actually installed on your computer. Running Ubuntu from the ??? /??? is a great way to test things out and allows you to try the default applications, browse the Internet, and get a general feel for the operating system. It’s also useful for checking that your computer hardware works properly in Ubuntu and that there are no major compatibility issues. To try out Ubuntu using the Live ??? /??? stick, insert the Ubuntu ??? into your ??? drive, or connect the ??? drive and restart your computer. A? r your computer ? nds the Live ??? /??? stick, and a quick loading screen, you will be presented with the “Welcome” screen. Using your mouse, select your language from the list on the le? , then click the bu? on labeled Try Ubuntu. Ubuntu will then start up, running directly from the Live ??? /??? drive. Once Ubuntu is up and running, you will see the default desktop. We will talk more about how to actually use Ubuntu in Chapter ? : ? e Ubuntu Desktop, but for now, feel free to test things out. Open some applications, change se? ings and generally explore—any changes you make will not be
In some cases, your computer will not recognize that the Ubuntu DVD or USB is present as it starts up and will start your existing operating system instead. Generally, this means that the priority given to boot devices when your computer is starting needs to be changed. For example, your computer might be set to look for information from your hard drive, and then to look for information on a DVD or USB. To run Ubuntu from the Live DVD or USB, we want the computer to look for information from the appropriate device ? rst. Changing your boot priority is usually handled by BIOS settings; this is beyond the scope of this guide.
If you need assistance with changing the boot priority, see your computer manufacturer’s documentation for more information. ???????????? ?? Figure 1. 1: The “Welcome” screen allows you to choose your language. saved once you exit, so you don’t need to worry about accidentally breaking anything. When you are ? nished exploring, restart your computer by clicking the “Power” bu? on in the top right corner of your screen (a circle with a line through the top) and then select Restart. Follow the prompts that appear on screen, including removing the Live ??? and pressing Enter when instructed, and then your computer will restart.
As long as the Live ??? is no longer in the drive, your computer will return to its original state as though nothing ever happened! Installing Ubuntu—Getting started Alternatively, you can also use your mouse to double-click the “Install Ubuntu 13. 04” icon that is visible on the desktop when using the Live DVD. This will start the Ubuntu installer. At least ? ?? of free space on your hard drive is required in order to install Ubuntu. We recommend ?? ?? or more. ?is will ensure that you will have plenty of room to install extra applications later on, as well as store your own documents, music, and photos.
To get started, place the Ubuntu ??? in your ??? drive and restart your computer. Your computer should load Ubuntu from the ???. When you ? rst start from the ??? , you will be presented with a screen asking you whether you want to ? rst try out Ubuntu or install it. Select the language you want to view the installer in and click on the Install Ubuntu bu? on. ?is will start the installation process. If you have an Internet connection, the installer will ask you if you would like to “Download updates while installing. ” We recommend you do so. ?e second option, “Install this third-party so? ware,” includes the Fluendo ??? odec, and so? ware required for some wireless hardware. If you are not connected to the Internet, the installer will help you set up a wireless connection. ?e “Preparing to install Ubuntu” screen will also let you know if you have enough disk space and if you are connected to a power source (in case you are installing Ubuntu on a laptop running on ba? ery). Once you have selected your choices, click Continue. Clicking on the underlined “release notes” link will open a web page containing any important information regarding the current version of Ubuntu. ?? ??????? ??????? ???? ?????? ??.?? Figure 1. 2: Preparing to install.
Internet connection If you are not connected to the Internet, the installer will ask you to choose a wireless network (if available). ?. Select Connect to this network, and then select your network from the list. ?. If the list does not appear immediately, wait until a triangle/arrow appears next to the network adapter, and then click the arrow to see the available networks. ?. In the Password ? eld, enter the network ??? or ??? key (if necessary). ?. Click Connect to continue. We recommend that you connect to the Internet during install, although updates and third-party software can be installed after installation completes.
Figure 1. 3: Set up wireless. Allocate drive space ?is next step is o? en referred to as partitioning. Partitioning is the process of allocating portions of your hard drive for a speci? c purpose. When you create a partition, you are essentially dividing up your hard drive into sections that will be used for di? erent types of information. Partitioning can sometimes seem complex to a new user; however, it does not have to be. In If you are installing on a new machine with no operating system, you will not get the ? rst option. The upgrade option is only available if you are upgrading from a previous version of Ubuntu. ???????????? ?? act, Ubuntu provides you with some options that greatly simplify this process. ?e Ubuntu installer will automatically detect any existing operating system installed on your machine, and present installation options suitable for your system. ?e options listed below depend on your speci? c system and may not all be available: ? ? ? ? Install alongside other operating systems Upgrade Ubuntu … to ??.?? Erase … and install Ubuntu Something else Install alongside other operating systems. If you are a Windows or Mac user and you are trying to install Ubuntu for the ? rst time, select the Install alongside other operating systems option. is option will enable you to choose which operating system you wish to use when you computer starts. Ubuntu will automatically detect the other operating system and install Ubuntu alongside it. For more complicated dual-booting setups, you will need to con? gure the partitions manually. Ubuntu provides you with the option of either replacing your existing operating system altogether, or installing Ubuntu alongside your existing system. The latter is called dualbooting. Whenever you turn on or restart your computer, you will be given the option to select which operating system you want to use for that session.
Figure 1. 4: Choose where you would like to install Ubuntu. Upgrade Ubuntu … to 13. 04 ?is option will keep all of your Documents, music, pictures, and other personal ? les. Installed so? ware will be kept when possible (not all your currently installed so? ware may be supported on the new version). Systemwide se? ings will be cleared. Erase disk and install Ubuntu Use this option if you want to erase your entire disk. ?is will delete any existing operating systems that are installed on that disk, such as Microso? Windows, and install Ubuntu in its place. is option is also useful if you have an empty hard drive, as Ubuntu will automatically create the necessary partitions for you. ?? ??????? ??????? ???? ?????? ??.?? Forma? ing a partition will destroy any data currently on the partition. Be sure to back up any data you want to save before forma? ing. A? er you have chosen the installation type, click Continue, or Install Now. Con? rm Partition choices and start install More information and detailed instructions on partitioning are available at: https://help. ubuntu. com/community/HowtoPartition. If you chose Something else, con? gure the partitions as you need.
Once you are happy with the way the partitions are going to be set up, click the Install Now bu? on at the bo? om right to move on. To reduce the time required for installation, Ubuntu will continue the installation process in the background while you con? gure important user details—like your username, password, keyboard se? ings and default timezone. Where are you? Figure 1. 5: Tell Ubuntu your location. ?e next screen will display a world map. Using your mouse, click your geographic location on the map to tell Ubuntu where you are. Alternatively, you can type your location in the ? ld below the map. ?is allows Ubuntu to con? gure your system clock and other location-based features. Click Continue when you are ready to move on. Keyboard layout Next, you need to tell Ubuntu what kind of keyboard you are using. In most cases, you will ? nd the suggested option satisfactory. If you are unsure which keyboard option to select, you can click the Detect Keyboard Layout bu? on to have Ubuntu determine the correct choice by asking you to press a series of keys. You can also manually choose your keyboard layout from the list of options. If you like, enter text into the box at the bo? m of the window to ensure you are happy with your selection, then click Continue. Who are you? Ubuntu needs to know some information about you so it can set up the primary user account on your computer. When con? gured, your name will ???????????? ?? Figure 1. 6: Verify that your keyboard layout is correct. appear on the login screen as well as the user menu, which we discuss in Chapter ? : ? e Ubuntu Desktop. On this screen you will need to tell Ubuntu: ? ? ? ? ? your name what you want to call your computer your desired username your desired password how you want Ubuntu to log you in
Figure 1. 7: Setup your user account. Enter your full name under Your name. ?e next text ? eld is the name your computer uses, for terminals and networks. You can change this to what you want, or keep the predetermined name. Next is your username, the name that is used for the user menu, your home folder, and behind the scenes. You will see this is automatically ? lled in for you with your ? rst name. Most people ? nd it easiest to stick with this. However, it can be changed if you prefer. Next, choose a password and enter it into both password ? elds.
When both passwords match, a strength rating will appear to the right that will show you whether your password is “too short,” “weak,” “fair,” or “strong. ” ?? ??????? ??????? ???? ?????? ??.?? You will be able to continue the installation process regardless of your password strength, but for security reasons it is best to choose a strong one. ?is is best achieved by having a password that is at least six characters long, and is a mixture of le? ers, numbers, symbols, and uppercase/lowercase. Avoid obvious passwords that include your birth date, spouse’s name, or the name of your pet. Login Options Finally, at the bo? m of this screen you have two options regarding how you wish to log in to Ubuntu. You may also choose to have Ubuntu encrypt your home folder. ? Log in automatically ? Require my password to log in – Encrypt my home folder Log in automatically Ubuntu will log in to your primary account automatically when you start up the computer so you won’t have to enter your username and password. ?is makes your login experience quicker and more convenient, but if privacy or security are important to you, we don’t recommend this option. Anyone who can physically access your computer will be able to turn it on and also access your ? es. Require my password to login ?is option is selected by default, as it will prevent unauthorized people from accessing your computer without knowing the password you created earlier. ?is is a good option for those who, for example, share their computer with other family members. Once the installation process has been completed, an additional login account can be created for each family member. Each person will then have their own login name and password, account preferences, Internet bookmarks, and personal storage space. Encrypt my home folder ?is option provides you with an added layer of security.
Your home folder is where your personal ? les are stored. By selecting this option, Ubuntu will automatically enable encryption on your home folder, meaning that ? les and folders must be decrypted using your password before they can be accessed. ?erefore if someone had physical access to your hard drive (for example, if your computer was stolen and the hard drive removed), they would not be able to see your ? les without knowing your password. If you choose this option, be careful not to enable automatic login at a later date. It will cause complications with your encrypted home folder, and will potentially lock you out of important ? es. Finishing Installation Ubuntu will now ? nish installing on your hard drive. As the installation progresses, a slideshow will give you an introduction to some of the default ???????????? ?? applications included with Ubuntu. ?ese applications are covered in more detail in Chapter ? : Working with Ubuntu. ?e slideshow will also highlight the Ubuntu support options: Figure 1. 8: Ubuntu community support options. Where to get help for Ubuntu. A? er approximately twenty minutes, the installation will complete and you will be able to click Restart Now to restart your computer and start Ubuntu. e ??? will be ejected, so remove it from your ??? drive and press Enter to continue. Figure 1. 9: You are now ready to restart your computer. Wait while your computer restarts, and you will then see the login window (unless you selected automatic login). ?? ??????? ??????? ???? ?????? ??.?? Login Screen A? er the installation has ? nished and your computer is restarted, you will be greeted by the login screen of Ubuntu. ?e login screen will present you with your username and you will have to enter the password to get past it. Click your username and enter your password.
Once done, you may click the arrow or press Enter to get into the Ubuntu desktop. Ubuntu’s login screen supports multiple users and also supports custom backgrounds for each user. In fact, Ubuntu automatically will pick up your current desktop wallpaper and set it as your login background. Ubuntu’s login screen also lets you select the di? erent environments to login. ?e login screen allows you to update your keyboard language, volume intensity and enable/disable accessibility se? ings before you log in to your desktop. It also displays date/time and ba? ery power for laptops.
You can also shut down or restart your system from the login screen. A guest session is also available at the login screen. You can activate this session for guests using your laptop or desktop. Figure 1. 10: Login Screen. 2 The Ubuntu Desktop Understanding the Ubuntu desktop Initially, you may notice many similarities between Ubuntu and other operating systems, such as Microso? Windows or Mac ?? ?. ?is is because they are all based on the concept of a graphical user interface (??? )—i. e. , you use your mouse to navigate the desktop, open applications, move ? les, and perform most other tasks.
In short, things are visually-oriented. ?is chapter is designed to help you become familiar with various applications and menus in Ubuntu so that you become con? dent in using the Ubuntu ???. Figure 2. 1: The Ubuntu 13. 04 default desktop. Unity All ??? -based operating systems use a desktop environment. Desktop environments encompass many things, including (but not limited to): ? ?e look and feel of your system ? ?e way the desktop is laid out ? How the desktop is navigated by the user In Linux distributions (such as Ubuntu), a number of desktop environments are available. Ubuntu uses Unity as the default desktop environment.
A? er installing and logging in to Ubuntu, you will see the Unity desktop. ?is initial view is comprised of the desktop background and two bars—a horizontal one located at the top of your desktop called the menu bar and a vertically-oriented bar at the far le? called the Launcher. To read more about other variants of Ubuntu, refer to Chapter 8: Learning More. ?? ??????? ??????? ???? ?????? ??.?? The Desktop Background Below the menu bar at the top of the screen is an image covering the entire desktop. ?is is the default desktop background, or wallpaper, belonging to the default Ubuntu ??.?? heme known as Ambiance. To learn more about customizing your desktop (including changing your background), see the section on Customizing your desktop below. The Menu Bar ?e menu bar incorporates common functions used in Ubuntu ??.??. ?e icons on the far-right of the menu bar are located in an area of the menu bar called the indicator area. Each installation of Ubuntu may contain slightly di? erent types and quantities of icons based on a number of factors, including the type of hardware and available on-board peripherals upon which the Ubuntu installation is based. e most common indicators are (starting from the le? ): Keyboard indicator ( ) allows you to select a keyboard layout and change your keyboard preferences. ?e keyboard indicator will only appear if you have chosen more than one keyboard layout in the keyboard se? ings during installation. Messaging indicator ( ) incorporates your social applications. From here, you can access instant messenger and email clients, a microblogging application, and Ubuntu One, your personal cloud. Network indicator ( ) manages network connections, allowing you to connect quickly and easily to a wired or wireless network.
Sound indicator ( ) provides an easy way to adjust the sound volume as well as access your music player and sound se? ings. Clock displays the current time and provides a link to your calendar and time and date se? ings. Session indicator ( ) is a link to the system se? ings, so? ware updates, printers, and session options (like locking your computer, logging out of a session, restarting the computer, or shu? ing down completely). Every application has a menuing system where di? erent actions can be executed in an application (like File, Edit, View, etc. ; the menuing system for an application is appropriately called the application menu. In Unity, the application menu isn’t on the title bar of the application as is commonly the case in other ??? environments. Instead, it is located to the le? area of the menu bar. To show an application’s menu, just move your mouse to the desktop’s menu bar (at the top of the screen). While your mouse is positioned here, the active application’s menu options will appear in the desktop’s menu bar, allowing you to use the application’s menuing options. Move your mouse away from the menu bar, and the desktop’s menu bar reappears. is capability in Unity to display the application’s menu only when needed is especially bene? cial for netbook and laptop users with limited viewable screen space. Apple uses a similar approach in ?? ? where all application menus appear on a bar at the top of the screen. It di? ers, however, in that the menus in Ubuntu appear only when the mouse is over the desktop’s menu bar. For more about: ? the Messaging Indicator see Using instant messaging; ? the Network Indicator see Getting online; ? the Session Indicator see Session options. Figure 2. 2: The indicators of the menu bar.
Note that some older applications may still display their menu within the application window. ??? ?????? ??????? ?? In previous versions of Ubuntu, the Nautilus ? le manager contained menu options in the title bar. In Ubuntu ??.?? , Nautilus received a fairly substantial overhaul. For one, Nautilus is now known as Files. Additionally, the menu bar was replaced with “always on” bu? ons in the upper-right hand portion of the window. ?ese “always on” bu? ons allow easier access to features and capabilities in the Files ? le manager without requiring the extra action of moving the mouse to the very top of the desktop.
A menu bar still exists with the Files ? le manager, but it only contains the menu Files. It looks like the title of the window, but it is actually a pull-down menu. The Launcher Figure 2. 3: The Ubuntu 13. 04 Launcher on the left with a sample of applications on it. ?e vertical bar of icons on the le? side of the desktop is called the Launcher. ?e Launcher provides easy access to applications, mounted devices, and the Trash. All running applications on your system will place an icon in the Launcher while the application is running. ?e ? rst icon at the top of the Launcher is the Dash, a component of Unity.
We will explore the Dash in a later section of this chapter. By default, other applications appear on the Launcher, including the Files ? le manager, LibreO? ce, Firefox, the workspace swit? er, any mounted devices, and, of course, the always-important Trash at the bo? om of the Launcher. If you open more applications than can be shown in the Launcher, the Launcher will “fold” the application icons at the bo? om of the Launcher. Simply move your mouse to the bo? om of the Launcher, and you’ll see the Launcher icons “slide” and the folded application icons unfold for easy access. Using the Launcher
Running applications The workspace switcher helps you navigate between workspaces. Trash contains deleted ? les. Tip: Pressing Super+S will show the content of the workspaces on one screen. Super key is also known as the Windows key (Win key). It is located between the left Ctrl key and Alt key. Furthermore, holding the Super key will cause Ubuntu to superimpose a number onto the ? rst ten applications in the Launcher and also display screen full of useful shortcuts (known as the Heads-Up Display discussed later in this chapter). You can launch an application with a number n on it by typing Super+n.
To run an application from the Launcher (or cause an already-running application to appear), just click on the application’s icon. Applications ?? ??????? ??????? ???? ?????? ??.?? that are currently running will have one or more triangles on the le? side of the icon indicating the number of application windows open for this application. Running applications also have a back-lit icon on the Launcher. ?e application in the foreground is indicated by a single white triangle on the right side of its icon. You can also run an application through the Dash which will be explored in the upcoming ? Dash section. An application is in the foreground when the application is on top of all other open application windows. Some also refer to an application in the foreground as being in focus. Figure 2. 4: Just below the Files icon, you will see the Firefox icon. Notice the triangle on the right side indicating it is the application in the foreground and the triangle on the left side indicating there’s only one window associated with Firefox at this time. Adding and removing applications from the Launcher ?ere are two ways to add an application to the Launcher: ? Open the Dash, ? d the application you wish to add to the Launcher, and drag its icon to the Launcher. ? Run the application you want to add to the Launcher, right-click on the application’s icon on the Launcher, and select Lo? to Laun? er. To remove an application from the Launcher, right-click on the application’s icon, then select Unlo? from Laun? er. The Dash ?e Dash helps you quickly ? nding applications and ? les on your computer. If you’ve used Windows in the past, you’ll ? nd the Dash to be similar to the Windows Start menu or the Start Screen in Windows ?. Mac users will ? nd the Dash similar to Launchpad in the dock.
If you’ve used a previous version of Ubuntu or another ????? Linux distribution, the Dash serves as a replacement for the various ????? ? menus. To explore the Dash, click on the top-most icon on the Launcher; the icon contains the Ubuntu logo on it. A? er clicking the Dash icon, the desktop will be overlaid by a translucent window with a search bar on top as well as a grouping of recently accessed applications, ? les, and downloads. Ubuntu also includes results from popular web services. ?e search bar provides dynamic results as you enter your search terms. ?e six lenses installed by default at the bo? m are links to your Home lens ( ), Applications lens ( ), Files and Folders lens ( ), Music lens ( ), Photo lens ( ), and Videos lens ( ). Lenses act as specialized search categories in the Dash. From the user’s perspective, lenses are simply icons. You’ll see the term lens and icon used interchangeably throughout this manual. To the Ubuntu purist, the pictures that appear horizontally at the bo? om of the Dash are lenses; to the rest, these are icons. The Dash allows you to search for information, both locally (installed applications, recent ? les, bookmarks, etc. ) as well as remotely (Twitter, Google Docs, etc. ).
This is accomplished by utilizing one or more lenses; each lens is responsible for providing a category of search results for the Dash. For more information about the Dash and its lenses, see: https://wiki. ubuntu. com/Unity. Many sites exist on the Internet dedicated to creating and releasing lenses for the Ubuntu Unity desktop. Some sites even teach you how to make your own lenses in order to maximize the operational e? ciencies of the Ubuntu Unity interface. Search for ? les and applications with the Dash ?e Dash is an extremely powerful tool allowing you to search your computer for applications and ? les. ??? ?????? ?????? ?? Figure 2. 5: The Dash Find ? les/folder ?e Dash can help you ? nd names of ? les or folders. Simply type a portion of the ? le or folder name. As you type, results will appear in the Dash. ?e Applications lens will also assist in ? nding ? les or folders—showing you the most recently accessed ? les as well as the most recent downloads. You can use the ? lter results bu? on in the top-right corner of the Dash to ? lter results by a? ributes such as ? le or folder modi? cation times, ? le type (. odt, . pdf, . doc, . txt, etc. ), or size. Find applications A standard Ubuntu installation comes with many applications.
Users can also download thousands more applications from the Ubuntu So? ware Center. As you collect an arsenal of awesome applications (and get a bonus point for alliteration! ), it may become di? cult to remember the name of a particular application; the Applications lens on the Dash can assist with this search. ?is lens will automatically categorize installed applications under “Recently Used,” “Installed,” or “More Suggestions. ” You can also enter a name of the application (or a part of it) into the search bar in the Dash, and the names of applications matching your search criteria will appear.
Even if you don’t remember the name of the application at all, type a keyword that is relevant to that application, and the Dash will ? nd it. For example, type music, and the Dash will show you the default music player and any music player you’ve used. External search results Ubuntu Software Center and software management will be discussed in detail at Chapter 5: Software Management. If you are new to the world of Ubuntu, be sure to read the Chapter 3: Working with Ubuntu. It will provide you assistance in choosing application(s) to suit your needs. In addition to searching your local computer for applications and ? es, the Dash will also search various online resources (e. g. , Amazon. com). Results pertinent to your search criteria are returned to you in the Dash. If you are concerned about local search terms being sent over the Internet, you can disable this feature in the Privacy section of the System Se? ings. ?? ??????? ??????? ???? ?????? ??.?? Figure 2. 6: You can see the default results when you press the Applications lens. ?e online search results within the Dash are turned on by default during installation. If you do not want external search results, go to System Settings ? Privacy ? Sear?
Results and set the “Include online search results” switch to the O? position.. As an added layer of privacy, you can also prevent any search activity from being recorded. Workspaces Workspaces are also known as virtual desktops. ?ese separate views of your desktop allow you to group applications together, and by doing so, help to reduce clu? er and improve desktop navigation. For example, you can open all of your media applications in one workspace, your o? ce suite in another, and your web browser in a third workspace. Ubuntu has four workspaces by default. ?e workspaces feature is not activated by default in Ubuntu ??.??.
To activate workspaces, click on System Indicator ? System Settings ? Appearance then click on the Behavior tab and click on the Enable workspaces box. When this box is checked, you’ll notice another icon is added to the bo? om of the Launcher that looks like a window pane. ?is is the workspaces switcher. Switching between workspaces If you’ve activated the workspace switcher as described above, you can switch between workspaces by clicking on the workspace switcher icon located on the Launcher. ?is utility allows you to toggle through the workspaces (whether they contain open applications or not) and choose the one you want to use.
Figure 2. 7: The workspace switcher on the Launcher. ??? ?????? ??????? ?? Managing windows When opening a program in Ubuntu (such as a web browser or a text editor —see Chapter ? : Working with Ubuntu for more information on using applications)—a window will appear on your desktop. ?e windows seen in Ubuntu are very similar to those in Microso? Windows or Mac ?? ?. Simply stated, a window is the box that appears on your screen when you start a program. In Ubuntu, the top part of a window (the title bar) will have the name of the application to the le? (most o? en, the title will be the same as the application’s name).
A window will also have three bu? ons in the top-le? corner. From le? to right, these bu? ons represent close window, minimize window, and maximize window. Other window management options are available by right-clicking anywhere on the title bar. Closing, maximizing, restoring, and minimizing windows To close a window, click on the close bu? on ( ) in the upper-le? corner of the window—the ? rst bu? on on the le? -hand side. ?e bu? on immediately to the right of the close bu? on is the minimize bu? on ( ) which removes the window from the visible screen and places it in the Launcher. ?is bu? n doesn’t close the application; it just hides the application from view. When an application is minimized to the Launcher, the le? -side of the icon in the Launcher will display a triangle showing you the application is still running. Clicking the icon of the minimized application will restore the window to its original position. Finally, the right-most bu? on is the maximize bu? on ( ) which causes the application to completely ? ll the unused displayable space on the desktop. Clicking the maximize bu? on again will return the window to its original size. If a window is maximized, its tople? bu? ns and menu are automatically hidden from view. To make them appear, just move your mouse to the menu bar. Moving and resizing windows Figure 2. 8: This is the top bar of a window, named title bar. The close, minimize, and maximize buttons are on the top-left corner of window. To move a window around the workspace, place the mouse pointer over the window’s title bar, then click and drag the window while continuing to hold down the le? mouse bu? on. To resize a window, place the pointer on an edge or corner of the window so that the pointer turns into a larger, two-sided arrow (known as the resize icon).
You can then click and drag to resize the window. Switching between open windows You can also move a window by holding the Alt key and then clicking and holding the left mouse button while pointing at title bar of the window and dragging the window to a new location. In Ubuntu, there are many ways to switch between open windows. ?. If the window is visible on your screen, click any portion of it to raise it above all other windows. ?. Use Alt+Tab to select the window you wish to work with. Hold down the Alt key, and keep pressing Tab until the window you’re looking for appears highlighted in the popup window. en, release the Alt key, and the application highlighted in the popup will move to the foreground of your desktop. Press Ctrl+Super+D to hide all windows and display the desktop; the same works to restore all windows. ?? ??????? ??????? ???? ?????? ??.?? ?. Click on the corresponding icon on the Launcher by moving your mouse to the le? side of the screen and right-clicking on the application’s icon. If the application has multiple windows open, double-click on the icon in order to select the desired window. Moving a window to di? erent workspace To move a window to a di? rent workspace, verify that the window isn’t maximized. If it is maximized, click on the right-most bu? on on the le? side of the title bar to restore it to its original size. ?en right-click on the window’s title bar and select: ? ? ? ? Move to Workspace Le? , to move the window to the le? workspace Move to Workspace Right, to move the window to the right workspace Move to Workspace Down, to move the window to the bo? om workspace Move to Another Workspace, and then choose the workspace to where you wish to move the window. The options available when moving windows to di? rent workspaces depends on which workspace contains the window you are moving. If the window exists in the lowerright workspace, you will not see a Move to Workspace Down because there is no workspace available below the lower-right quadrant of a four quadrant workspace. Window always on the top or on visible workspace At times, you may want to force a window to always be in the foreground so that it can be seen or monitored while you work with other applications. For example, you may want to browse the web and, at the same time, view and answer incoming instant message.
To keep a window always in the foreground, right-click on the window’s title bar, then select Always On Top. ?is window will now be on the top of all windows opened in the current workspace. If you want to have a window always on the top regardless of the workspace, right-click on the window’s title bar, then select Always on Visible Workspace. ?is window will now be on top of all other windows across all workspaces. Browsing ? les on your computer ?ere are two ways to locate ? les on your computer—search for them or access them directly from their folder. You can search for a ? le using the Dash or the Files ? e manager. You can also use the Dash or Files ? le manager to access commonly used folders (such as Documents, Music, Downloads) as well as the most recently accessed ? les. Your Home Folder You can open your Home folder from the Launcher. ?e Home folder is used to store personal ? les. Your Home folder matches your login name and is created when your user account is created. When opening your personal folder, you will see a collection of several folders, including Desktop (which contains any ? les that are visible on the desktop), Documents, Downloads, Music, Pictures, Public, Templates, and Videos. ese folders are created automatically during the installation process. You can add more ? les and folders as needed. Files ? le manager Just as Windows has Windows Explorer and Mac ?? ? has Finder to browse ? les and folders, Ubuntu ??.?? uses the Files ? le manager by default. In previous versions of Ubuntu, this ? le manager was called Nautilus. ??? ?????? ??????? ?? The Files ? le manager window When you select the Home Folder shortcut in the Launcher, click on a folder in the Dash, or double-click on a folder on the desktop, the Files ? le manager window opens. e default window contains the following features: menu bar ? e menu bar is located at the top of the screen. ?e Files menu allows you to modify the layout of the browser, show, browse and remove bookmarks, open a Help document, open a new window, connect to a server, or quit. Choosing Enter Location will open the Locations text ? eld where you can enter any location directly. title bar ? e title bar shows the name of the currently selected folder. It also contains the Close, Minimize, and Maximize bu? ons. tool bar On the right side of the tool bar, there are ? ve bu? ons:Sear? represented by a magnifying glass), View items as a grid, View items as a list, View options (represented by a down arrow), and Location options (represented by a cog); clicking on the Sear? icon opens a ? eld so you can search for a ? le or folder by name. Clicking on the options bu? ons Location options or View options opens a menu with options. On the le? side of the toolbar, you will see a representation of your current browsing. ?is is similar to the history function in most browsers; it keeps track of where you are and allows you to backtrack if necessary. You can click on any of the locations to navigate back through the ? e browser. ?e bu? ons Previous location and Next location allow you to navigate through previously visited locations. le? pane ? e le? pane of the ? le browser has shortcuts to commonly used folders. When a folder is bookmarked, it appears in the le? pane. No ma? er what folder is open, the le? pane will always contain the same folders. central pane ? e largest pane shows the ? les and folders in the directory that you are currently browsing. If you bookmark a folder, it will appear in the Bookmarks menu as well as in the left pane. You can use the option hide/show sidebar from the View options menu. Figure 2. 9: Files ? e manager displaying your home folder. Navigating Files To navigate between folders, use the bookmarks in the le? pane of the Files ? le manager. You can also retrace your steps by clicking on the name of a folder in the path bar. Double-clicking on a visible folder will cause you to navigate to it. What is a Directory? Or a Folder? A directory is a division of space in a ? le system used to organize ? les. A folder is the name given to a directory in a Graphical User Interface (GUI) environment like the Files ? le manager. ?? ??????? ??????? ???? ?????? ??.?? Opening ? les A ? le, in its simplest form, is data.
Data can represent a text document, database information, or data that will be used to produce music or videos. To open a ? le, you can either double-click on its icon or right-click the icon and select one of the Open With options. Ubuntu a? empts to determine the best application to use when opening the selected ? le, and most of the time, Ubuntu chooses correctly. However, if you want to open the ? le using an application other than what is selected, choose Open With ? Other Application. A selection of installed applications will appear. Make your selection, and the ? le will a? empt to open using the selected application.
Creating new folders To create a new folder from within the Files ? le manager, right-click in a blank area in the ? le manager and select New Folder from the popup menu (this action will also work on the desktop). Replace the default “Untitled Folder” title with your desired label (e. g. , “Personal Finances”). You can also create a new folder by pressing Ctrl+Shift+N. Hidden Files and Folders If you wish to hide certain folders or ? les, place a dot (. ) in front of the name (e. g. , “. Personal Finances”). In some cases, it is impossible to hide ? les and folders without pre? xing them with a dot. Copying and moving ? es and folders You can easily view hidden ? les by clicking View options ? Show Hidden Files or by pressing Ctrl+H. Hiding ? les with a dot (. ) is not a security measure—it simply provides a way to keep folders organized and tidy. You can copy ? les or folders in the Files ? le manager by right-clicking on the item and selecting Copy from the popup menu. When using the Edit menu in the Files ? le manager, make sure you’ve selected the ? le or folder you want to copy ? rst (by le? -clicking on it once). Multiple ? les can be selected by le? -clicking in an empty space (i. e. , not on a ? le or folder), holding the mouse bu? n down, and dragging the cursor across the desired ? les or folders. ?is “click-drag” action is useful when you are selecting items that are grouped closely together. To select multiple ? les or folders that are not positioned next to each other, hold down the Ctrl key while clicking on each item individually. Once the desired ? les and/or folders are selected, right-click on any of the selected items to perform an action just like you would for a single item. When one or more items have been “copied,” navigate to the desired location, then right-click in an empty area of the window and select Paste to copy them to the new location.
While the copy command can be used to make a duplicate of a ? le or folder in a new location, the cut command can be used to move ? les and folders. ?at is, a copy will be placed in a new location, and the original will be removed from its current location. To move a ? le or folder, select the item to move, then click Edit ? Cut. Navigate to the desired location, then click Edit ? Paste. As with the copy command above, you can also perform this action using the right-click menu, and it will work for multiple ? les or folders at once. An alternative way to move a ? e or folder is to click on the item, and then drag it to the new location. You can also use the keyboard shortcuts Ctrl+X, Ctrl+C, and Ctrl+V to cut, copy, and paste ? les and folders respectively. When you “cut” or “copy” a ? le or folder, nothing will happen until you “paste” it somewhere. Paste will only a? ect the most recent item that was cut or copied. If you click on a ? le or folder, drag it, then hold down the Alt key and drop it to your destination folder, a menu will appear asking whether you want to copy, move, or link the item. ??? ?????? ??????? ?? Using multiple tabs and multiple Files windows
Opening multiple Files ? le manager windows can be useful for dragging ? les and folders between locations. ?e option of tabs (as well as panes) is also available in the Files ? le manager. To open a second windows when browsing a folder in Files, select File ? New Window or press Ctrl+N. ?is will open a new window, allowing you to drag ? les and/or folders between two locations. To open a new tab, click File ? New Tab or press Ctrl+T. A new row will appear above the space used for browsing your ? les containing two tabs—both will display the directory you were originally browsing.
You can click these tabs to switch between them to click and drag ? les or folders between tabs the same as you would between windows. You can also open a second pane in Files so you can see two locations at once without having to switch between tabs or windows. Dragging ? les and folders between panes is a quick way to move or copy items. Searching for ? les and folders on your computer When dragging items between Files windows, tabs, or panes, a small symbol will appear over the mouse cursor to let you know which action will be performed when you release the mouse button.
A plus sign (+) indicates you are about to copy the item, whereas a small arrow means the item will be moved. The default action will depend on the folders you are using. You can search for ? les and folders using the Dash or the Files ? le manager. Search using the Dash Search for ? les and folders quickly by pressing Ctrl+F in Files and then typing what you want to ? nd. In the Dash, simply type your search terms in the search bar at the top of the Dash. Alternatively, you may use the Applications or Files & Folders lenses; here you can use a ? lter to narrow down your search.
Open the drop-down menu on the right side of the search bar. If you’ve selected Applications, you will be able to ? lter by application type. If you’ve chosen Files & Folders, you can ? lter by a host of options, including Last modi? ed, Type (e. g. , Documents), or Size. It is su? cient to type the ? rst few le? ers of the ? le or folder for which you are searching. Search using Files ? le manager In Files ? le manager, click on the magnifying glass bu? on or press Ctrl+F. ?is opens the search ? eld where you can type the name of the ? le or folder you want to ? nd. Customizing your desktop
One of the advantages to a windowed environment through Unity is the ability to change the look and feel of your desktop. Don’t like the default Ubuntu theme? Do you have a picture of your third cousin’s aunt’s uncle’s nephew’s pet chihuahua that you’d love to see on your desktop as wallpaper? All of this (and more) is possible through desktop customizations in Unity. Most customizations can be reached via the Session Indicator and then selecting System Settings to open the System Se? ings application window. ?e Dash, desktop appearance, themes, wallpapers, accessibility, and other con? guration se? ngs are available here. For more information see Session options. ?? ??????? ??????? ???? ?????? ??.?? Figure 2. 10: You can change most of your system’s settings here. Figure 2. 11: You can change the theme in the Look tab of the “Appearance” window. Appearance The Look tab ?rough the Look tab you can change the background, fonts, and window theme to further modify the look and feel of your desktop. To begin, open Appearance by either right-clicking on your background and selecting Change Desktop Ba? ground or selecting Session Indicator ? System Settings ? Appearance. Select the Look tab. ?eme ? “Appearance” window will display the current selected background wallpaper and theme. ?emes control the appearance of your windows, bu? ons, scroll bars, panels, icons, and other parts of the desktop. ?e Ambiance theme is used by default, but there are other themes from which you can choose. Just click once on any of the listed themes to give a new theme a try. ?e theme will change your desktop appearance immediately. Desktop background Under Ba? ground, you may choose from Wallpapers, Pictures Folder, or Colors and Gradients. When Wallpapers is selected, you will see Ubuntu’s default selection of backgrounds.
To change ??? ?????? ??????? ?? the background simply click the picture you would like to use. You’re not limited to this selection. To use one of your own pictures, click the + button and navigate to the image you would like to use. ?en double-click the image, and the change will take e? ect immediately. ?is image will then be added to your list of available backgrounds. Selecting Pictures Folder opens your Pictures folder where you can choose a picture for the background. ?e Colors and Gradients bu? on allows you to set the background to a solid or gradient color. Click on the Solid Color bu? on, then the Pi? Color to choose a solid color. ?e Vertical Gradient and Horizontal Gradient bu? ons bring up two Pi? a Color bu? ons. Just choose any two colors you like and see if you have achieved the desired result. Launcher icon size At the bo? om of the Look tab you ? nd a slider to change the size of icons on the Launcher. You may choose from a range between ?? and ?? pixels. The Behavior tab ?rough the behavior tab there are several options to change the behavior of your desktop. Auto-hide the Launcher Switch the Auto-hide the Laun? er to either show the Launcher or revealing it when moving the pointer to the de? ed hot spot. When turned on, you can choose the reveal location—Le? side or Top le? corner—and the reveal sensitivity. Enable workspaces By default, workspaces are not enabled. You can enable workspaces by checking this option. Add show desktop icon to the launcher Check this option if you want to show the desktop icon on the Launcher. Accessibility Ubuntu has built-in tools that make using the computer easier for people with certain physical limitations. You can ? nd these tools by opening the Dash and searching for “Universal Access” or by selecting Session Indicator ?
System Settings ? Universal Access. On the Seeing tab you can manage the text size, the contrast of the interfaces, enable a zoom tool or even a screen reader. Selecting high-contrast themes and larger on-screen fonts can assist those with vision di? culties. You can activate “Visual Alerts” through the Hearing tab if you have hearing impairment. Also you can adjust keyboard and mouse se? ings to suit your needs through the Typing and Pointing and Cli? ing tabs, respectively. Orca screen reader Orca is a useful tool for people with visual impairments. Orca comes preinstalled in Ubuntu.
To run Orca, click on the Dash, type Orca, and click on the displayed result. Orca is the “Screen Reader” part of Universal Access and can be launched once the “Screen Reader” is activated. Orca’s voice synthesizer will activate and assist you through the various options such as voice type, voice language, Braille, and screen magni? cation. Once ?? ??????? ??????? ???? ?????? ??.??

When you log back in, the Orca se? ings you selected will automatically run every time you use your computer. Session options When you have ? nished working on your computer, you can choose to log out, suspend, restart, or shut down through the Session Indicator on the far right side of the top panel. Logging out Logging out will leave the computer running but return the desktop to the login screen. ?is is useful for switching between users, such as when a di? erent person wishes to log in to their account or if you are ever instructed to “log out and back in again. You can also log out by pressing Ctrl+Alt+Del. Suspend Before logging out, you should always verify that you have saved your work in any open application. To save energy, you can put your computer into suspend mode which will save the current opened applications to internal memory, power o? all internal devices and hardware, and allow you to start back up more quickly. While in a suspended state, the computer will use just a trickle of energy; this is required because the session is saved to internal memory, and if no power goes to internal memory, the data will be lost. Rebooting
To reboot your computer, select Shut Down… from the “Session Indicator” and click the Restart icon. Shut down To totally power down your computer, select Shut Down… from the “Session Indicator” and click Shutdown. ??? ?????? ??????? ?? Other options From the Session Indicator, you can select Start Screensaver to require a password before using the computer again—this is useful if you need to leave your computer for some duration. Getting help General Help You can lock your screen quickly by using the keyboard shortcut Ctrl+Alt+L. Locking your screen is recommended if you move away from your computer for a short amount of time.
Like with any other operating system, Ubuntu has a built-in help reference called the Ubuntu Desktop Guide. To access it, click on the Dash and type Help. Alternatively, you can press F1 while on the desktop, or select Ubuntu Help from the Help menu in the menu bar. Heads-Up Display help Many applications have their own help section which can be accessed by clicking the Help menu within the application window. Figure 2. 13: The HUD (heads-up display) shows application-speci? c help information based on your general input. ?e ??? (heads-up display) is a keyboard-friendly utility to help you ? d commands, features, and preferences embedded deep within the stacked menu structure of an application. Activate the ??? by tapping the le? Alt key on the keyboard. If you want to know how to load Rhythmbox, the default music player in Ubuntu, then just type rhythmbox in the ??? and the options related to Rhythmbox will come up in the list of matching results. You can press the Enter key to active the command. ?e ??? also works for some applications running under WINE. ??? comes in handy in applications with deep menus such as LibreO? ce and Gimp. Online Help WINE is an acronym for Wine Is Not an Emulator.
It allows you to run some Windows-based applications in Ubuntu. Discussion of how to use WINE is beyond the scope of this manual, but it is worth checking out if you need to run Windows applications under Ubuntu. If you can’t ? nd an answer to your question in this manual or in the Ubuntu Desktop Guide, you can contact the Ubuntu community through the Ubuntu Forums (http://ubuntuforums. org). Many Ubuntu users open an account on the forums to receive help, and in turn provide support to others as they gain more knowledge. Another useful resource is the Ubuntu Wiki (https://wiki. ubuntu. com), a website maintained by the Ubuntu community.
We encourage you to check any information you ? nd on other websites with multiple sources when possible, but only follow directions if you understand them completely. ?? ??????? ??????? ???? ?????? ??.??

Getting online ?is section of the manual will help you to check your connection to the Internet and help you con? gure it where needed. Ubuntu can connect to the Internet using a wired, wireless, or dialup connection. Ubuntu also supports more advanced connection methods, which will be brie? y discussed at the end of this section. ?? ??????? ??????? ???? ?????? ??.?? A wired connection is when your computer connects to the Internet using an Ethernet cable. ?is is usually connected to a wall socket or a networking device—like a switch or a router.
A wireless connection is when your computer connects to the Internet using a wireless radio network—usually known as Wi-Fi. Most routers now come with wireless capability, as do most laptops and netbooks. Because of this, Wi-Fi is the most common connection type for these types of devices. Wireless connectivity makes laptops and netbooks more portable when moving to di? erent rooms of a house and while traveling. A dialup connection is when your computer uses a modem to connect to the Internet through a telephone line. NetworkManager In order to connect wirelessly, you must be in a location with a working wireless network.
To set up your own wireless network, you will need to purchase and install a wireless router or access point. Some locations may already have a publicly accessible wireless networks available. If you are unsure whether your computer has a wireless card, check with your manufacturer. In order to connect to the Internet using Ubuntu, you need to use the NetworkManager utility. NetworkManager allows you to turn network connections on or o? , manage wired and wireless networks, and make other network connections, such as dial up, mobile broadband, and ??? s. You can access NetworkManager by using its icon found the top panel. is icon may look di? erent depending on your current connection state. Clicking this icon will reveal a list of available network connections. ?e current connection (if any) will have the word “disconnect” underneath it. You can click on “disconnect” to manually disconnect from that network. ?is menu also allows you to view technical details about your current connection or edit all connection se? ings. In the image to the right you will see a check mark next to “Enable Networking. ” Deselect “Enable Networking” to disable all network connections. Select “Enable Networking” to enable networking again. is can be very useful when you are required to turn o? all wireless communications, like in an airplane. Establishing a wired connection (a) (b) (c) Figure 3. 1: The network connection states: (a) disconnected, (b) wired, and (c) wireless. Figure 3. 2: Here you can see the currently active connection is “Wired connection 1. ” If you have an Ethernet cable running from a wall socket or networking device, such as a switch or router, then you will want to setup a wired connection in Ubuntu. In order to connect to the Internet with a wired connection, you need to know whether your network supports ???? (Dynamic Host Con? uration Protocol). ???? is a way for your computer to automatically be con? gured to access your network and/or Internet connection. ???? is usually automatically con? gured on your router. ?is is usually the quickest and easiest way of establishing a connection to the Internet. If you are unsure whether your router is setup to use ???? , you may wish to contact your ??? ’s (Internet Service Provider) customer service line to check. If your router isn’t con? gured to use ???? then they will also be able to tell you what con? guration se? ings you need in order to get online. Automatic connections with DHCP
Are you already online? If the NetworkManager icon in the top panel shows a connection then you may have successfully connected during the Ubuntu setup process. You can also simply open a browser and see if you have access to the Internet. If so, you do not need to do anything for the rest of this section. If your network supports ???? then you may already be set up for online access. To check this, click on the NetworkManager icon. ?ere should be a “Wired Network” heading in the menu. If “Wired connection ? ” appears directly underneath, then your machine is currently connected and probably setup for ????.
If “Disconnected” appears in gray underneath the wired network section, look below to see if an option labeled “Wired connecFigure 3. 3: This window displays your IP address and other connection information. ??????? ???? ?????? ?? tion ? ” appears in the list. If so, click on it to a? empt to establish a wired connection. To check if you are online, click on the NetworkManager icon in the top panel and select the Connection Information option. You should see a window showing details of your connection. If your ?? address is displayed as ?.?.?.? or starts with ???.??? then your computer was not successfully assigned connection information through ????. If it shows another address (e. g. , ???.???.???.??? ), then it is likely that your ???? connection to the router was successful. To test your Internet connection, you may want to open the Firefox web browser to try loading a web page. More information on using Firefox can be found later in this chapter. Manual con? guration with static address An IP (Internet Protocol) address is a unique number assigned to your machine so that your router can identify you on the network. Think of it like a phone number for your computer.
Having this unique address allows the router to speak to your computer, and therefore send/receive data. If you are still not online after following these steps, you may need to try setting up your network connection manually using a static IP address. If your network does not support ???? then you need to know a few items of information before you can get online. If you do not know any of this information, then you call your ???. ? An ?? address—? is is a unique address used for identifying your computer on the network. An ?? address is always given in four numbered groups, separated by dots, for example, ???.???.???.??.
When connecting using ???? , this address will periodically change (hence, the name “dynamic”). However, if you have con? gured a static ?? address, your ?? address will never change. ? A network mask—? is tells your computer the size of the network to which it is being connected. It is forma? ed the same way as the ?? address, but usually looks something like ???.???.???.?. ? A gateway—? is is the ?? address of the device that your machine looks to for access to the Internet. Usually, this will be the router’s ?? address. ? ??? server—? is is the ?? address of the ??? (Domain Name Service) server. ??? s what your computer uses to resolve ?? addresses to domain names. For example http://www. ubuntu. com resolves to ??.???.??.???. ?is is the ?? address of the Ubuntu website on the Internet. ??? is used so you don’t have to remember ?? addresses. Domain names (like ubuntu. com) are much easier to remember. You will need at least one ??? server address but you can enter up to three addresses in case one server is unavailable. To manually con? gure a wired connection, click on the NetworkManager icon and select Edit Connections. Make sure you are looking at the “Wired” tab inside the “Network Connections” window. e list may already have an entry, such as “Wired connection ? ” or a similar name. If a connection is listed, select it and click the Edit bu? on. If no connection is listed, click the Add bu? on. If you are adding a connection, you need to provide a name for the connection. ?is will distinguish the connection being added from any other connections added in future. In the “Connection Name” ? eld, choose a name such as “Wired Home. ” To setup the connection: ?. Make sure that the Connect automatically option is selected under the connection name. ?. Switch to the ?? v? Settings tab. ?.
Change the Method to “Manual. ” ?. Click on the Add bu? on next to the empty list of addresses. If you do not know your ISP’s DNS server addresses, Google has DNS servers that anyone in the world can use for free. The addresses of these servers are: Primary—8. 8. 8. 8 Secondary—8. 8. 4. 4. ?? ??????? ??????? ???? ?????? ??.?? Figure 3. 4: In this window you can manually edit a connection. ?. Enter your ?? address in the ? eld below the Address header. ?. Click to the right of the ?? address, directly below the Netmask header and enter your network mask. If you are unsure, “???.???.???.? ” is the most common. . Click on the right of the network mask directly below the Gateway header and enter the address of your gateway. ?. In the ??? Servers ? eld below, enter the address of your ??? server(s). If you are entering more than one, separate them with commas—for example, “?.?.?.? , ?.?.?.? ”. ?. Click Save to save your changes. When you have returned to the Network Connections screen, your newly added connection should now be listed. Click Close to return to the desktop. If your connection was con? gured correctly, the NetworkManager icon should have changed to show an active wired connection.
To test if your connection is properly set up, simply open a web browser. If you can access the Internet, then you are connected! Wireless If your computer is equipped with a wireless (Wi-Fi) card and you have a wireless network nearby, you should be able to set up a wireless connection in Ubuntu. Connecting to a wireless network for the ? rst time If your computer has a wireless network card, you can connect to a wireless network. Most laptops and netbooks have a built-in wireless networking card. Ubuntu is usually able to detect any wireless network in range of your computer.
To see a list of wireless networks, click on the NetworkManager icon. Under the “Wireless Networks” heading you should see a list of available wireless networks. Each network will be shown by its name and a signal meter to the le? showing its relative signal strength. ?e signal meter looks like a set of bars similar to what is seen when viewing signal strength of a cell phone. Simply put, the more bars, the stronger the signal. A wireless network can be open to anyone, or it can be protected with a password. A small padlock will be displayed by the signal bar if any wireless network within range are password-protected.
You will need to A MAC address is a hardware address for your computer’s network card. Entering this information is sometimes important when using a cable modem connection. If you know the MAC address of your network card, this can be entered in the appropriate text ? eld in the Wired tab of the editing window. To ? nd the MAC addresses for all installed networking devices, open a terminal window, and at the command line prompt, type ifconfig. This will display a lot of information about each of the network devices installed on the computer. The wired devices will be labeled as LAN0, LAN1, etc.
The wireless devices will appear as WLAN0, WLAN1, etc. To improve speed and reliability of your wireless connection, try moving closer to your router or wireless access point. ??????? ???? ?????? ?? know the correct password in order to connect to these secured wireless networks. To connect to a wireless network, select the desired network by clicking on its name within the list. ?is will be the name that was used during the installation of the wireless router or access point. Most ??? s (Internet service providers) provide pre-con? gured routers with a sticker on them detailing the current wireless network name and password.
Most publicly accessible wireless networks will be easily identi? able by the name used for the wireless network—for example “Starbucks-Wireless. ” If the network is unprotected (i. e. , the signal meter does not show a padlock), a connection should be established within a few seconds—and without a password required. ?e NetworkManager icon in the top panel will animate as Ubuntu a? empts to connect to the network. If the connection is successful, the icon will change to display a signal meter. An on-screen noti? cation message will also appear informing you that the connection was successful.
If the network is password-protected, Ubuntu will display a window called “Wireless Network Authentication Required” as it tries to make a connection. ?is means that a valid password is required to make a connection. ?is is what the screen should look like: Figure 3. 5: Enter your wireless network password. If you know the password, enter it in the Password ? eld and then click on the Connect bu? on. As you type the password, it will be obscured from view to prevent others from reading the password as you type it. Once the password is entered, click on the Connect bu? on. e NetworkManager icon in the top panel will animate as Ubuntu a? empts to connect to the network. If the connection is successful, the icon will change to display a signal meter. An on-screen noti? cation message will also appear informing you that the connection was successful. If you entered the password incorrectly, or if it doesn’t match the correct password (for example if it has recently been changed and you have forgo? en), NetworkManager will make another a? empt to connect to the network, and the “Wireless Network Authentication Required” window will re-appear so that you can re-type the password.
You can hit the Cancel button to abort the connection. If you do not know the correct password, you may need to call your ??? ’s customer support line or contact your network administrator. Once you have successfully established a wireless connection, Ubuntu will store these se? ings (including the password) to make it easier to connect to this same wireless network in the future. You may also be prompted to select a keyring password here. ?e keyring stores passwords in one place so you can access them all in the future by remembering just the keyring password.
To verify the characters you are entering for the password, you can view the password by selecting the Show Password check box. Then, you can make the password obscure again by deselecting the Show password check box. ?? ??????? ??????? ???? ?????? ??.?? Connecting to a saved wireless network Ubuntu will automatically try to connect to a wireless network in range if it has the se? ings saved. ?is works on both open and secure wireless networks. If you have numerous wireless networks in range that are saved on your computer, Ubuntu may choose to connect to one network while you may want to connect to another network.
To remedy this action, click on the NetworkManager icon. A list of wireless networks will appear along with their signal meters. Simply click on the network to which you wish to connect, and Ubuntu will disconnect from the current network and a? empt to connect to the one you have selected. If the network is secure and Ubuntu has the details for this network saved, Ubuntu will automatically connect. If the details for this network connection are not saved, are incorrect, or have changed, then you will be prompted to enter the network password again.
If the network is open (no password required), all of this will happen automatically and the connection will be established. Connecting to a hidden wireless network In some environments, you may need to connect to a hidden wireless network. ?ese hidden networks do not broadcast their names, and, therefore, their names will not appear in the list of available wireless networks even if they are in range. In order to connect to a hidden wireless network, you will need to get its name and security details from your network administrator or ???. To connect to a hidden wireless network: ?. Click on
