Bug#594623: xserver-xorg-video-intel with 855GM

[<dmsoler@edu.xunta.es>]

Package: xserver-xorg-video-intel  
Version: 2:2.12.0+legacy1-1

Hi.

Apparently, I have the same hardware of the original reporter of this bug:

00:02.0 VGA compatible controller [0300]: Intel Corporation 82852/855GM Integrated Graphics Device [8086:3582] (rev 02)
00:02.1 Display controller [0380]: Intel Corporation 82852/855GM Integrated Graphics Device [8086:3582] (rev 02)

I have compiled a new kernel with package linux-source-2.6.32 (version 2.6.32-21), commenting out the blacklisted 855GM in file drivers/gpu/drm/i915/i915_drv.c :

 	{ },
 };

xserver-xorg-video-intel version 2:2.12.0+legacy1-1 is working with this i915 kernel module in KMS mode. I have some X crashes, but NEVER WHILE ACTIVELY WORKING WITH THE COMPUTER (until now, it never happened with this or with previous xserver-xorg-video-intel packages or kernels), only when the computer is idle or xscreensaver is active. 2.12.0+legacy1-1 is better than previous version, since when X crashes, it is always correctly restarted by gdm (with 2.9, when X crashed, it couldn't be restarted: the box was working - you could use the console or ssh - but gdm couldn't restart X, and manually restarting X got the computer frozen).

With 2.12.0+legacy1-1, if I boot with i915.modeset=0 in UMS mode, the computer freezes when starting X with GDM (blank screen, no network access).

When I have time, I'll try to compile your shadow version and see what happens. Is there a .deb package of the shadow version? It would be easier to try.

Thanks.
