[Dri-users] Intel 915GM

[Moritz B. <m....@we...>]

Hi!

I have got an Intel 915GM graphic chip that I am trying to get to work
with Linux. I was able to have it supported with xorg 11R7.0-1 and the
according kernel modules built-in (2.6.15.2). Low and behold!, hardware
acceleration was turned on according to glxinfo. Even though this was at
least working, it had a severe problem with fullscreen mode when using
OpenGL: Instead of actually stretching the image over the whole screen,
it either remained a "window" the size of the configured resolution (cf.
Quake III-based games) or was placed at the center of the screen with
the surrounding parts of the screen being black.

So I tried and changed this situation, obviously without much success. I
downloaded the latest common, i810 and i915 snapshot releases from
<http://dri.freedesktop.org/snapshots/>. Compilation succeeded, but when
I tried to insert the modules I got

FATAL: Error inserting i915
(/lib/modules/2.6.15.2/kernel/drivers/char/drm/i915.ko): Unknown symbol
in module, or unknown parameter (see dmesg)

with dmesg stating
kobject_register failed for drm (-17)
 [<c027637b>] kobject_register+0x6b/0x80
 [<c0137ef3>] mod_sysfs_setup+0x63/0xe0
 [<c01393bb>] load_module+0x96b/0xaa0

 [<c0103257>] sysenter_past_esp+0x54/0x75
i915: Unknown symbol drm_cleanup_pci

1) How could I get proper DRI support with fullscreen mode?

2) What files do I have to change in order to revert the changes common,
i810 and i915 have applied to the system -- even after changing some
files in /usr/lib/xorg/modules/ (dri-old.*), I still can't get GLcore
and GLX to be loaded?

Every help appreciated!
Thanks in advance
Moritz
