Salut,
Alors, j’ai réinstallé tout le système Debian à neuf, comme ça je suis reparti sur une machine saine.
J’ai compris le problème avec l’installation de “xserver-xorg-video-nividia”.
Je n’avais ni installé ni paramétré les dépots “non free” et “contrib”.
Cette fois c’est fait plus de problème de ce côté.
Cependant, j’ai toujours les mêmes erreurs qui reviennent:
[ 73.316967] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) /dev/dri/card0: failed to set DRM interface version 1.4: Permission denied
[ 73.316994] [ERROR]Aborting because fallback start is disabled.
j’ai modifié le fichier xorg.conf.nvidia avec vi en ajoutant la section:
Section "Screen"
Identifier "Default Screen"
Device "DiscreteNvidia"
EndSection
ce qui devait corriger le problème mais après redémarrage de Bumblebee et redémarrage de la machine, l’erreur persiste.
Voici ce qu’il y a dans mon xorg.conf.nvidia:
Section "Screen"
Identifier "Default Screen"
Device "DiscreteNvidia"
EndSection
Section "ServerLayout"
Identifier "Layout0"
Option "AutoAddDevices" "false"
Option "AutoAddGPU" "false"
EndSection
Section "Device"
Identifier "DiscreteNvidia"
Driver "nvidia"
VendorName "NVIDIA Corporation"
# If the X server does not automatically detect your VGA device,
# you can manually set it here.
# To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
# as you see in the commented example.
# This Setting may be needed in some platforms with more than one
# nvidia card, which may confuse the proprietary driver (e.g.,
# trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
# BusID "PCI:01:00:0"
# Setting ProbeAllGpus to false prevents the new proprietary driver
# instance spawned to try to control the integrated graphics card,
# which is already being managed outside bumblebee.
# This option doesn't hurt and it is required on platforms running
# more than one nvidia graphics card with the proprietary driver.
# (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
# If this option is not set, the new Xorg may blacken the screen and
# render it unusable (unless you have some way to run killall Xorg).
Option "ProbeAllGpus" "false"
Option "NoLogo" "true"
Option "UseEDID" "false"
Option "UseDisplayDevice" "none"
