[Intel-gfx] 915GM/GMS/910GML Express Graphics Controller with 1280x1024 Mode Display

[Érico Teixeira]

Hello,
I've the following card in my laptop:
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 04)

I'm using Debain lenny with kernel 2.6.26-1-686

I've installed the Graphics Driver as described in:
http://intellinuxgraphics.org/install.html 

I've also changed my xorg.conf as this: 
# xorg.conf (X.Org 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 xorg.conf manual page.
# (Type "man 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 command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I'm not beeing able to load 1280x1024 resolution

I've checked /var/log/Xorg.0.log and found this: 
(EE) [drm] drmOpen failed.
(EE) intel(0): [dri] DRIScreenInit failed. Disabling DRI.
...

If I change 
Driver "i810" 
for
Driver "intel"
X won't load 

1. How can I check if all libs and necessary modules were installed correctly ?
2. Is DRI not loading issue dirctly related to this ?

Érico
