Forum Linux.gui Configuration de Xorg

Bonjour,

je suis en train de me battre avec Xorg sur un portable Toshiba s3000-x4 contenant une carte mère Intel 82830 m. La configuration automatique (sous ubuntu 6.06.1 LTS) ne donne rien de bon, le mieux que j'ai réussi à obtenir est d'avoir un affichage correct uniquement si un écran est branché sur la sortie VGA :

Quelqu'un a une idée de ce qui cloche ?
