[i915] Initialises before agpgart

This is actually a problem with your video driver as it is not supporting hardware acceleration. Compiz is doing the right thing by refusing to run as it cannot do so in this environment.

Ok. While logging out and back in did nothing, restarting fixed this problem. Still, it would be good to know why it didn't work until I restarted.

Ok. That's odd. The problem here appears to be here:
[ 5.228897] Linux agpgart interface v0.103

[ 5.739308] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xc0000000

It looks like a race between the drm driver and agp setups; drm has bailed because it's tried to access the agpgart, but that module seems to be currently initialising.

I'm moving this to the kernel, where the drm modules belong. How often can you reproduce this? Does it happen only on the first boot from power-off, or seemingly at random?

Upstream has tightened the agp dependency for i915 recently and it has not made it back to stable yet. The fix looks to be easily applied to lucid's kernel.

Previously linked git commit in patch format.

What information needs to be added to make this bug report complete?

I've nominated this for Lucid; this is a regression of bug #430694 in 9.10, the patch for which we probably dropped during the 2.6.33 backport. We can now pick upstream's patch, though.

@Roger -- as you say when backporting drm 2.6.33 wholesale half of the linkage fix we had was lost. Indeed it looks simplest to revert the remainder of our fix and pull in the upstream version. Pushed patches for that to our list for review.

Hi,
I have reported this bug before - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/555049
and because my bug is considered the same as this one I will report my new problem here.
I could not activate the visual effect only ones after a fresh install and after that visual effects could be switched on/off pretty well.
After I have upgraded to Lucid 64bit beta-2, I can't turn them all again...

This bug was fixed in the package linux - 2.6.32-20.29

Hi again,
I still can't enable the visual effects on my system.
I have downloaded the most recent updates and now my kernel version is:
2.6.32-21-generic
When my system loads all windows don't have decorations (the caption area where are the close, maximize, minimize buttons is missing).
When I open the Appearance dialog and try to switch between the effects/non-effects modes, ubuntu is searching for driver,
a window pop-ups and asking me if I want to stay with the new settings (by the way in this stage the windows captions are back), and if I choose to stay with the new settings, the effects are still disabled.

By the way, when I try to start compiz manually, I get:

arkadi@arkadi-laptop:~$ compiz --replace
Couldn't find a perfect decorator match; trying all decorators
Found no decorator to start

I don't know what changes you did and where but I prefer lucid beta-1, at least there I could turn on the visual effects...
Maybe some one could point me out what to downgrade so the the visual effects will work again?

Arkashkin: you dont have compiz-gnome installed for some reason, its not related to this bug

I still see this on the .34 kernels (and the standard .32 Lucid kernels).

Thanks a lot, it really solved my problem.
I was writing here only because I have opened this bug report - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/555049, and after some time I was told that it is related to this bug, and I thought this problem is related to this problem also.

Again, thank you very much.
