Bref je lai decommentee et ca demarre. Mais en mode restreint seulement, et je ne sais pas pourquoi.
Le demon dbus est bien lance au demarrage de la machine. Comment voir si il y a un probleme avec pulseaudio ?
je me permets de mettre une partie du fichier log de xorg, si ca peut vous aider (moi ca ne dit pas grand chose
