The existence of a similar workaround doesn't imply that the bug is the

I'm also suffering under this issues. My hw is i945GM in sony vaio
sz1xp, distribution is ubuntu interpid with Jaunty xorg-edgers ppa
packages. I always compile my own kernel which exactly suits my hw, and
have tux on ice support.
When I'm on 2.6.28 kernel, I'm able to enable GEM via UXA option in
mrvanes: I shouldn't be commenting on this, since its not in its own
bug, but with the DRI2 drivers, I believe you'll find there is a problem
with syncing to VBlank. Try turning off sync to vblank in the compiz
settings. For me, this made a difference of 1frame every 3 seconds ->
complety usable.
I'm not sure if this is the same problem as I has but I recently
stumbled on a dead-slow compiz after getting DRI2/UXA to work on my
jaunty install using a intel 965 and xorg-edgers ppa.
I nailed to problem down to the compiz-wrapper (/usr/bin/compiz) not
using -indirect-rendering when UXA/DRI2 is
Upgrading from edgers repository helped a bit.
Now I have hw acceleration on.

Missing a few things in my last comment:
don't *have* GEM support...

Don't know how that happened. I guess I type these in a hurry.

Problem persists in newest updates; in fact, it seems to be even worse.
Further, we still don't GEM support in our DRM drivers. I'd also like to
report that earlier I had tested the drivers and X server from Xorg-
edgers, which did have this problem at all (though it did have another

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.
To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.
So you have a couple
If im Correct this is a bug for both kernel and intel driver.
With ubuntu kernel i get 130 fps on glxgears
With vanilla 2.6.28-rc9 i get 380fps
this i have with ubuntu kernel too:
mtrr: no MTRR for d000,1000 found
now i will try to bisect intel driver. Or some body doing this?

I can confirm that Compiz (along with everything else 3D) still runs
very slowly, with glxgears running at around 200FPS (or about 300FPS
with card0 permissions set properly). This is after applying the latest
updates.
