Resolution ecran qui "saute"

Bonjour à tous,

Voic un decriptif rapide de ma configuration... J'ai un PC (Ubuntu 6.06) équipé d'une CM D845GBF et donc d'un chipset graphique Intel intégré 82865G le tout sur un ecran LG 19" TFT en résolution 1280x1024.
Je précise (je ne sais pas si justement il y a un lien) que j'ai 3 PC relié à cet écran par l'intermédiaire d'un KVM qui gère le 1280x1024...

Voici maintenant mon problème : Il arrive, assez aléatoirement, qu'après un reboot ma résolution repasse en 640x480 et impossible de basculé en 1280x1024 via l'interface graphique (choix des résolutions bridé à 640x480).
Si je fais un CTRL + ALT + Return... Poufff... je repasse bien en 1280x1024 ...

Any idea ??

Ci-dessous mon xorg.conf :

Re : Resolution ecran qui "saute"

Bonjour,
peut-être en ajoutant les lignes

HorizSync    28.0 - 64.0
VertRefresh  43.0 - 60.0

dans la section "Monitor" du fichier xorg.conf ...
Pour l'éditer, utiliser la commande 'sudo nano /etc/X11/xorg.conf' dans un terminal
puis relancer le serveur X avec un Ctrl+Alt+BckSpc.
