J'ai installé une Ubuntu Gutsy sur un iMac G5. L'écran est un 20 pouces , avec une résolution de 168x1050. à‡a s'est bien passé sauf que l'affichage dans Xorg est un peu décalé: les (environ) vingt premières colonnes de pixels affichées à partir du bord gauche de l'écran sont en fait les colonnes du bord droit de l'affichage normal.
Quand je passe en console (ctrl+alt+f1), l'affichage par framebuffer est impeccable.
Dans le xorg.conf, je vois que le pilote utilisé est "nv" . J'ai essayé de démarrer xorg avec le pilote "vesa" mais ça n'a pas démarré.
Voilà ce que dit lspci sur la carte graphique :
0000:f0:10.0 VGA compatible controller: nVidia Corporation NV34M [GeForce FX Go5200] (rev a1)
Quelqu'un a déjà eu ce problème ?
