If you have a supported video card, but find that you are not able to turn on the Desktop Effects,
check that your X server started properly. In particular, make sure that your /etc/X11/xorg.conf
file is properly configured. Make sure that DRI and GLX are loaded in the Module section. Also, add
an extensions section anywhere in the file (typically at the end of the file) that appears as follows:
Section ???extensions???
Option ???Composite???
EndSection

Getting into the Desktop 3
FIGURE 3-13
Alt+Tab through thumbnails of active windows with AIGLX desktop effects enabled.
Another option is to add the following line to the /etc/X11/xorg.conf file in the Device section:
Option ???XAANoOffscreenPixmaps???
The XAANoOffscreenPixmaps option will improve performance. Check your /var/log/
Xorg.log file to make sure that DRI and AIGLX features were started correctly. The messages in
that file can help you debug other problems as well.
Changing GNOME Preferences
There are many ways to change the behavior, look, and feel of your GNOME desktop. Most
GNOME preferences can be modified from selections on the Preferences menu (select System???
Preferences).
Unlike earlier versions of GNOME for Fedora, boundaries between preferences related to the
window manager (Metacity), file manager (Nautilus), and the GNOME desktop itself have been
blurred.
