Salut tout le monde,
Suite à l’acquisition d’un laptop vaioVGN-B1XP avec un chipset graphique i855GME, je me trouve en face du problème suivant : l’affichage et le défilement des fenêtres ou avec le navigateur internet saccadent.
J’ai lu pas mal de doc et parcouru le forum sans vraiment trouver comment régler mon souci.
J’utilise le driver i810, et le module i915 est chargé :
debian:/home/drunkenboxing# lsmod |grep i915
i915 21280 1
drm 73908 2 i915
glxgears me retourne 250fps en moyenne.
debian:/home/drunkenboxing# glxinfo |grep rendering
direct rendering: No
Je vous laisse mon xorg.conf :

Si j’active “composite” “enable” dans la section extensions glxgears me retourne une image saccadée et 100 fps environ.
Je ne sais plus trop quoi tester ou quoi ajouter comme option.
Merci de m’éclairer si quelqu’un possède ce circuit video et parvient à le faire fonctionner parfaitement.
Je précise c’est un centrino avec 1 Go de ram, donc de problème côté mémoire vive.
