ce problème semble s'être éteint
et je ne sais pas comment
mais maintenant mon pilote nvidia pose problème
j'ai lancé le NVIDIA X server settings et il me dit:
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
phil@phil-laptop:~$ sudo su
[sudo] password for phil:
root@phil-laptop:/home/phil# nvidia-xconfig
Using X configuration file: "/etc/X11/xorg.conf".
VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.
Device section "Configured Video Device" must have a Driver
line.
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf'
root@phil-laptop:/home/phil#
comment le réactiver?
