Extrait de mon tuto EeePC :
Le fichier xorg.conf est vraiment minimal dans le nouveau Xorg 7.3
Voilà ce que j’ai ajouté pour que Compiz et Cie fonctionne au mieux :
/etc/X11/xorg.conf :
[code]
xorg.conf (X.Org X Window System server configuration file)
This file was generated by dexconf, the Debian X Configuration tool, using
values from the debconf database.
Edit this file with caution, and see the xorg.conf manual page.
(Type “man xorg.conf” at the shell prompt.)
This file is automatically updated on xserver-xorg package upgrades only
if it has not been modified since the last upgrade of the xserver-xorg
package.
If you have edited this file but would like it to be automatically updated
again, run the following command:
sudo dpkg-reconfigure -phigh xserver-xorg

Enfin, pour que l’accélération 3D soit activée :
On peut le vérifier ensuite par :
$ glxinfo | grep direct
direct rendering: Yes
Les options composite, dri 666 et Cie, c’est pour compiz.
L’option DPMS dans la section monitor, c’est pour la gestion de l’économie d’energie de l’écran. Si cette option est absente, l’extinction automatique de l’écran ne fonctionnera pas.
