Salut à tous ! Encore un boulet qui comprend rien à comment marchent les drivers sous linux 
!
J’ai un notebook asus R409L avec une carte graphique nvidia 820M .
J’ai installé debian avec le DVD “complet” (la dernière version dispo sur le site).
Mon problème est que je n’arrive pas à installer le driver propriétaire de nvidia.
Voici mon xorg.conf actuellement avec le driver libre :

Seulement dès que je met
Driver "nvidia"ou
Driver "nv"au lieu de
Driver "fbdev"j’ai un écran noir quand je lance x mais pas d’erreur.
J’ai l’erreur “no screen found” si je met en driver nvidia et que j’enlève
BusID "4:00:00" Voici le log de ladite erreur dans /etc/X11/xorg.0.log:

Je précise que j’ai installé le driver proprio via les paquets officiels et trois éexécutables différents du site et que dans tous les cas ça a pas marché (même en utilisant nvidia-xconfigure) (et oui j’ai supprimé l’un avant de rajouter l’autre).
Donc voilà ça m’emmerde un peu : j’aimerais bien utiliser le driver propriétaire car là j’ai un affichage dégueu notamment avec ma souris qui disparaît sans raison, et je pense que passer sur le driver proprio pourrait résoudre le problème 
!
Merci d’avance pour vos réponses des gros bisous
