J'ai ajouté un Modeline et j'ai le xorg.conf suivant.

Je progresse parce que maintenant je peux sélectionner la résolution 1280x1024. Par contre, ça me coupe le haut de l'écran... Bizarre non?
Et puis 1024x768 reste la résolution par défaut.
Et si je passe en 1280x1024 et que je sauvegarde xorg.conf, la partie "Screen" est modifiée comme ça :
