Bonjour,

Je viens vers vous car je n'arrive pas à installer la prise en charge 3D sur mon ordinateur. Après recherches en différents endroits, je me permets de poster ceci.

J'utilise Ubuntu 5.04 hoary.

Il s'agit d'un ordinateur portable, et pour ce qui est de la carte graphique, je vous poste le résultat de la commande lspci -v | less :

0000:00:00.0 Host bridge: VIA Technologies, Inc. P/KN266 Host Bridge
        Subsystem: Unknown device 1631:e004
        Flags: bus master, 66MHz, medium devsel, latency 8
        Memory at a0000000 (32-bit, prefetchable) 
        Capabilities: [a0] AGP version 2.0
        Capabilities: [c0] Power Management version 2

0000:01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 KM266/KL266]
(prog-if 00 [VGA])
        Subsystem: Unknown device 1631:e004
        Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 255
        Memory at e0000000 (32-bit, non-prefetchable) 
        Memory at 90000000 (32-bit, prefetchable) 
        Expansion ROM at 000c0000 [disabled] 
        Capabilities: [dc] Power Management version 2
        Capabilities: [80] AGP version 2.0

Les symptômes sont assez énervants, le simple fait de réduire une fenêtre ou créer un rectangle de sélection me cause des ralentissements conséquents.

J'ai modifié mon fichier xorg.conf de la façon suivante :

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands:
#
#   cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
#   sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'
#   sudo dpkg-reconfigure xserver-xorg

La commande glxgears me renvoie le résultat suivant :

arno@ubuntu:~$ glxgears
369 frames in 7.0 seconds = 52.714 FPS
114 frames in 7.0 seconds = 16.286 FPS

Ce qui n'est pas terrible...
