Mais j'ai peur que la ne soit pas le probleme, car mon X marche parfaitement, c'est quand je veux passer a une console (ctrl-alt-F*) ou quand je quitte qu'il me met 'out of frequency'. J'en deduit donc que c'est le 'framebuffer' ou je ne sais quoi qui est configuré avec une résolution trop basse .... (quand je reviens sur X, X fonctionne normalement ...)
