Bonjour,

je viens d'installer mandriva sur mon laptop,
quand je voudrais changer de résolution par exemple utiliser le 1280x800,
puis quand je test j'ai plein de couleur genre Arc-en-Ciel ?

je suis obliger de rester en mode : 1440x900 ?

j'ai une carte graphique GeForce GO 6100 et sur le panel c'est indiqué : nvidia gforce FX to gforce 8800, c'est normal ?

j'ai ceci dans le configurer le serveur d'affichage :

carte graphique : nvidia gforce FX to gforce 8800
Moniteur : Flat Panel 1440x900
Résolution : 1440x900 24Bpp
