2.5. Customizing your GNOME
The sub-menu of the
menu offers many customization
options for your GNOME session. Below are some of the highlights.
2.5.1. Configuring your Background
Figure 2-16. The Desktop Background Preferences tool
One way to dramatically alter the appearance of your graphical
desktop is to change the background using the
Desktop Background Preferences
tool. You can choose from several background images included
with Red Hat Enterprise Linux in the
directory, or you can use your own image. To start the
Desktop Background Preferences
tool, right-click on the desktop and choose
The Desktop Background Preferences
tool allows you to load a background from a directory of
To add images to the list of available backgrounds, you can
either drag them from your directory into the list (which does
not move the file) or you can click the Add
Wallpaper button and select image files on your
There are several ways to display your images. The
Tiled option displays multiple instances
of your image across the desktop, which is useful if you use a
small image or if you use a tile (or pattern) image from
(or from your own image collection). The
Centered option places your image in the
center of the desktop, leaving the default background colors
to fill in any remaining desktop space. To fill the desktop
with an image without tiling it, use the
Scaled or Stretched
To create a background with your own custom colors
and no images, choose the No Wallpaper
option and adjust your colors below Desktop
Colors. You can choose either a solid
color or a gradient of two colors. Clicking on the color
buttons allows you to change the colors. Click

2.5.2. Keyboard Shortcuts
Figure 2-18. The Keyboard Shortcuts application
You can create keyboard shortcuts — pressing a combination of
keys on the keyboard — to perform actions within an
application or on your desktop. Open the
Keyboard Shortcuts application from
sub-menu. The application
provides a list of every action to which you can assign a
shortcut. It might be helpful to spend a few moments looking
at the default shortcuts; using them can be a great
time-saver. Scroll through the list until you find the action
you would like to assign a shortcut. Click once on the
description of the action, and then press the keystrokes that
you would like to use as a shortcut.
To create a keyboard shortcut to switch between workspaces
by pressing [Ctrl]-[Alt]
and workspace number:
Click on Switch to workspace
The Keyboard Shortcut
application records that these were the keys pressed, and
lists that under the Shortcut column.
(The application notifies you if the keystrokes you have
chosen are already used for another action.)
Repeat this process for workspaces 2-4, assigning
each of them similar keystrokes.
Close the Keyboard
Shortcuts application to save your
at any time takes you to Workspace 2. Likewise, pressing
takes you to workspace 3,
takes you to workspace 4, and
takes you back to workspace 1.
The Sound preference tool allows
you to set sounds to accompany events. For example, your
system can play a certain sound every time you login. When you
first open this tool, you should see a series of tabs across
the top of the window. Under the General
tab, check that the Enable sound server
startup box is checked.
Figure 2-19. The Sound Configuration tool
Click on the Sound Events tab, to display a list
of actions that can be accompanied by a sound. To change or
add a sound to an event, click on the description of the
event, then click on the Browse...
button. Choose a sound located in the file system, and then
click Open. Sound files installed with
Red Hat Enterprise Linux are located in
/usr/share/sounds/. You may
also choose a sound file from your home directory. Any file
with a .wav extension can be used for an event sound. To
listen to a sound that has been selected, click the
Play button. (If you do not hear a
sound, follow the steps in Section 10.3 Troubleshooting Your Sound Card.) When you are finished,
close the Sound tool, and your
changes are saved.

Figure 2-21. The screensaver tool
Double-click the Screensaver icon to launch
the Screensaver Preferences tool.
The list on the left displays the available screensavers.
Nearly all screensavers can be customized by clicking on the
Settings... button. To see if this is
the screensaver you would like to use, click on the
Preview button. When you have seen
enough, click the mouse anywhere on the screen and you will
return to Screensaver Preferences.
When you are finished, close the window to save your
changes and exit.
2.5.5. Removable Storage
Figure 2-22. Options for usage of removable storage
Launch the tool from the
=> sub-menu. The application opens a
list of options for the way your system handles removable
storage media such as floppy diskettes and CD-ROMs. One
default option is auto-mounting.
Auto-mount means that the data on your removable media is
automatically available a few moments after you insert it;
manual mounting is not necessary. For more information on
removable media, refer to Chapter 13 Diskettes and CD-ROMs or the
Red Hat Enterprise Linux System Administration Guide.
