ati X700 probleme resolution ecran, driver libre/propriétaire

:)Bonjour,

Je viens d'installer ubuntu feisty fawn sur un acer aspire 5020 avec une ati X700, et j'ai quelques petits problèmes , que je viens vous exposez après avoir chercher aide et réconfort sur le forum en vein .

Ma résolution d'écran est actuellement de 800x600 lorsque j'utilise le driver libre ati et je n'arrive pas à passer en 1200x800 même en le spécifiant dans le xorg. Alors que quand j'utilise le driver proprio aucun problème pour passer en 1200x800. Mais bon quitte à être sur ubuntu autant éssayer d'utiliser le plus de libre possible ^^.

Je vous poste mon xorg en espérant que quelqu'un puisse venir m'éclairer, merci d'avance:
