All \acronym{GUI}-based operating systems use a \emph{desktop environment}. Desktop environments encompass many things, such as the look and feel of your system, as well as how the desktop is organized, laid out, and navigated by the user. In Linux distributions (such as Ubuntu), there are a number of desktop environments available for use. One of the most popular desktop environments is called \acronym{GNOME}, which is used by default in Ubuntu. \acronym{KDE}, \acronym{XFCE}, and \acronym{LXDE} are other popular desktop environments (used in Kubuntu, Xubuntu, and Lubuntu, respectively), and there are many more. As Ubuntu is based on \acronym{GNOME}, we will limit our discussion in this guide to exploring your \acronym{GNOME} desktop.

When you first log in to Ubuntu after installing it to your hard drive, you will see the \acronym{GNOME} desktop. Ubuntu is highly customizable, as is the \acronym{GNOME} desktop, but for now let's just explore the default layout that is in front of you.

At first glance, you will notice many similarities between Ubuntu and other operating systems such as Windows or Mac \acronym{OS~X}. This is because they are all based on the concept of a graphical user interface (\gls{GUI})\dash that is, you use your mouse to navigate the desktop, open programs, move files, and perform most other tasks. In short, things are very visually oriented, which means it is important for you to become familiar with where and what to click in Ubuntu.

Next, choose a password and enter it into the first password field on the left, then type the same again into the right field to verify. When both passwords match, a strength rating will appear on the right that will tell 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, however, for security reasons it is best to choose a strong one. This is best achieved by having a password that is at least six characters long, and is a mixture of letters, numbers, symbols, and uppercase/lowercase. For extra security, avoid obvious passwords like your birth date, spouse's name, or the name of your pet.

This option provides you with an extra layer of security. Your home folder is where your personal files are stored. By selecting this option, Ubuntu will automatically enable encryption on your home folder, meaning that files and folders must be \emph{decrypted} using your password before they can be accessed. Therefore if someone had physical access to your hard drive (for example, if your computer was stolen and the hard drive removed), they would still not be able to see your files without knowing your password. \warning{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 files.}

This option is selected by default, as it will prevent unauthorized people from accessing your computer without knowing the password you created earlier. This is a good option for those that, 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.

Now you need to decide on your computer's name. Again, this will be filled in for you automatically using the login name you entered above (it will say something like ``john-desktop'' or ``john-laptop.''), however, it can be changed if you prefer. Your computer name will mainly be used for identifying your computer if you are on a home or office network with multiple other computers. To learn more about setting up a network, refer to \chaplink{ch:default-applications}.

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. This makes your login experience quicker and more convenient, however, if privacy or security are important to you, this option is not recommended. Anyone who can physically access your computer will be able to turn it on and also access your files.

Next, choose a password and enter it into the first password field on the left, then type the same again into the right field to verify. When both passwords match, a strength rating will appear on the right that will tell 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, however, for security reasons it is best to choose a strong one. This is best achieved by having a password that is at least six characters long, and is a mixture of letters, numbers, symbols, and uppercase/lowercase. For extra security, avoid obvious passwords like your birth date, spouse's name, or the name of your pet.

Finally, at the bottom of this screen you have three options to choose from regarding how you want to log in to Ubuntu.

Require my password to login

Require my password to login and decrypt my home folder

The last screen summarizes your install settings, including any changes that will be made to the partitions on your hard drive. Note the warning about data being destroyed on any removed or formatted partitions\dash if you have important information on your hard drive that is not backed up, now would be a good time to check that you have set up your partitions correctly. \marginnote{You should not need to click the \button{Advanced} button unless you wish to change your bootloader settings or network proxy. These are more advanced tasks and beyond the scope of this guide.} Once you have made sure that all the settings are correct, click on \button{Install} to begin the installation process.

Ubuntu will now install. As the installation progresses, a slideshow will give you an introduction to some of the default applications included with Ubuntu. These applications are covered in more detail in \chaplink{ch:default-applications}.

After approximately twenty minutes, the installation will complete and you will be able to click \button{Restart Now} to restart your computer and start Ubuntu. The \acronym{CD} will be ejected, so remove it from your \acronym{CD} drive and press \keystroke{Enter} to continue.

Wait while your computer restarts, and you will then see the login window (unless you selected automatic login).

Click your username and enter your password, then press \keystroke{Enter} or click \button{Log in}. You will then be logged in to Ubuntu and will be presented with your new desktop!

The \menu{Accessories} sub-menu has many programs that are suited for productivity, including \application{Calculator} and \application{Tomboy Notes}.

Ubuntu has several games built in for your entertainment. If you enjoy card games, check out \application{AisleRiot Solitaire}. Perhaps you're looking for more of a challenge: in that case, there's \application{gBrainy} and \application{Sudoku}. The \menu{Games} menu also includes \application{Mahjongg}, \application{Mines} (similar to Windows' Minesweeper game) and \application{Quadrapassel} (similar to Tetris).
