\marginnote{While modern graphical \glspl{desktop environment} have generally replaced early command-line interfaces, the command line can still be a quick and efficient way of performing many tasks. See \chaplink{ch:command-line} for more information, and \chaplink{ch:the-ubuntu-desktop} to learn more about \gls{GNOME} and other desktop environments.} Linux was designed from the ground up with security and hardware compatibility in mind, and is currently one of the most popular \Index{Unix}-based operating systems. One of the benefits of Linux is that it is incredibly flexible and can be configured to run on almost any device\dash from the smallest micro-computers and cellphones to larger super-computers. \Index{Unix} was entirely command line--based until graphical user interfaces (\glspl{GUI}) began to emerge in the early 1990s.

The \window{Appearance Preferences} window will initially display the \button{Theme} tab when it opens. Here you can select a theme that will control the appearance of your windows, buttons, scroll bars, panels, icons, and other parts of the desktop. The ``Ambiance'' theme is used by default, but there are seven other themes you can choose from. Just click once on the theme you want to try, and the changes will take effect immediately.

To save energy, you can put your computer into suspend mode, which will save its current condition and allow you to start more quickly while remaining on but using very little energy. Suspending the computer spins down the hard disk and saves your session to memory, so it is very quick to suspend and resume from suspension.

\marginnote{You can lock your screen quickly by using the keyboard shortcut \keystroke{Ctrl+Alt+L}. Locking your screen is recommended if you move away from your computer for a short amount of time.} From the session menu, you can also select \menu{Lock Screen} to require a password before using the computer again \dash this is useful if you need to leave your computer for some duration. You can also use the session menu to set up a guest session for a friend to try Ubuntu, or to \emph{switch users} to log into another user account without closing your applications.

If you can't find an answer to your question in this manual or in the \application{Ubuntu Help Center}, you can contact the Ubuntu community through the Ubuntu Forums (\url{http://ubuntuforums.org}). \marginnote{We encourage you to check any information you find on other websites with multiple sources when possible, but only follow directions if you understand them completely.} 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 (\url{https://wiki.ubuntu.com}), a website maintained by the Ubuntu community.

This margin note is confusing to me - are you saying that to connect to a network (\ie, access files from my home computer with my laptop) I do the same thing as connecting to the Internet? This is not the case and will probably confuse people so have removed it for now. \marginnote{In this guide we will limit our discussion to connecting to the Internet. However, connecting to a home or office network is usually performed in a similar manner.}

\marginnote{If you are unsure whether your computer has a wireless card, check with your manufacturer.} In order to connect to the Internet in Ubuntu, you need to use the \application{NetworkManager} utility. NetworkManager allows you to turn all networking on or off, and helps you manage your wired, wireless, and other connections.

You can also right-click on the \application{NetworkManager} icon. This will open a menu allowing you to enable or disable networking, view technical details about your current connection, or edit all connection settings. In the image above, the check box next to ``Enable Networking'' is currently selected; you can deselect it to disable all network connections. This may be useful if you need to shut off all wireless communication, such as when in an airplane.

\gltodo{``\acronym{DHCP},'' ``\acronym{ISP}''} \marginnote{Are you already online? If the NetworkManager icon in the top panel shows a connection, then you may have successfully connected during the installation process. If so, you do not need to follow the rest of this section.} In order to connect with a wired connection, you need to know whether your network connection supports \gls{DHCP}. This stands for ``Dynamic Host Configuration Protocol,'' and is a way for computers on your network to automatically receive configuration information from your Internet service provider (\gls{ISP}). This is usually the quickest and easiest way of establishing a connection between your computer and your \acronym{ISP} in order to access the Internet, although some \acronym{ISP}s may provide what is called a \emph{static address} instead. If you are unsure whether your \acronym{ISP} supports \acronym{DHCP}, you may wish to contact their customer service line to check. They will also be able to provide you with information on your static address if one has been allocated to you (in many cases \acronym{ISP}s only allocate static addresses to customers upon request).
