[Intel-gfx] xserver/driver from git and kernel drm from stable vanilla kernel

[Tomas Carnecky]

Hi folks,

I'm new to this list but not to the xorg community. I recently decided 
to join the intel-gfx list to help debug and test the intel driver. So 
far I haven't had much luck.. with getting the latest git code to run 
properly. That also means I have found bugs, yay!

First of all, I'm running drm, mesa, xserver and the intel driver from 
the git master branches, everything else in the userspace is from gentoo 
stable. I can't test the lastest drm kernel bits because of #17085, so I 
use the vanilla 2.6.26.2 kernel. Graphics chip is GM965.
I installed the everything from git under /opt/xorg, to be able to 
switch between the stable installation and latest xorg bits.

With this setup the basic 2D desktop (gnome, metacity) works. But 3D 
doesn't very well, glxgears runs at 45fps and when I start compiz it 
corrupts the whole screen and makes it unusable (all I see is a black 
screen with occasional colored pixels, the cursor works fine though). If 
If log into the machine using ssh, I can kill compiz and start metacity 
and everything goes back to normal.

I don't think my setup is that uncommon, in fact I think even when you 
release the drm kernel code people will still be using .25 or .26 
kernels for a long time. So you need to make sure that the latest driver 
will work with earlier kernels that don't support GEM.

Do you want me to file a bug? I would like to avoid that if it's 
something as easy as updating userspace headers or libraries or such.
