D’après les infos que j’ai trouvé, ça devrait venir du fichier xorg.conf
Je l’ai modifié, et ça donne ceci:
[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

Malheureusement j’ai toujours le même soucis…
D’autres pistes à me conseiller?!
