Bonjour,
Tout nouveau, je poste car il m’est impossible d’activer l’accélération matérielle de ma carte vidéo.
J’ai utilisé le tuto Nvidia Facile - Installation des pilotes nvidia pour Debian mais rien n’y fait 
.
La machine est à base de carte mère ASUS AT5ION-I. La distribution est la Debian Squeeze (cat /etc/debian_version -> 6.0.2).
Un petit coup d’uname -a donne :
root@casimir:~# uname -a
Linux casimir 2.6.32-5-686 #1 SMP Mon Jun 13 04:13:06 UTC 2011 i686 GNU/Linux
La carte vidéo est la ION2 (lspci | grep VGA) :

Et malheureusement, quand je fais le test glxinfo 
:
root@casimir:~# glxinfo
name of display: :1.0
display: :1 screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

server glx version string: 1.2
server glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
client glx vendor string: NVIDIA Corporation
client glx version string: 1.4
...
La conf xorg est présente (ls /etc/X11) :
root@casimir:~# ls /etc/X11
app-defaults rgb.txt xinit xorg.conf.backup Xresources Xsession.options
default-display-manager twm xkb Xreset Xsession XvMCConfig

VendorName "NVIDIA Corporation"
EndSection
Je pense que je dois faire une boulette quelque part mais après plusieurs installations et réinstallations, je ne sais plus vraiment ou chercher… Je vais oser installer la dernière version ubuntu pour voir comment cela se comporte. Mais je souhaiterai rester sous la souche d’origine Debian.
Merci pour votre aide.
