Using X Compositing
To use the X Compositing method, the X Composite Extension must be
enabled, and your window manager must have compositing enabled. This
method removes flickering that occurs with Internal Software Compositing.
To turn on X Compositing
NOTE X Compositing is turned on by default on Red Hat 6 and Fedora 14 systems,
so you do not have to modify the xorg.conf file.
1 Open the /etc/X11/xorg.conf file.
2 Turn on X Compositing as follows:
Section "Extensions"
Option "Composite" "true"
EndSection
3 Save the xorg.conf file.
