I am using the kernels of #46 for 3-4 days and I had no such issue since
then. My display adapter is:

Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller])
(It uses the i915 module)
In ccsm, I have
Hmm, I'm using an Intel Corporation Mobile GM965/GL960 Integrated
Graphics Controller. I've reinstalled the test kernel, maybe something
else is triggering the freeze for me. . .

Since I installed this kernel, the freeze did not occur again.
I tested with Sync to VBlank enabled and disabled - no freeze.
Tests included xset dpms, lid close/open, video playback, flash, ..

Wait, are you guys referring to 2.6.38-9, or 2.6.39-1.6? I haven't tried
2.6.39-1.6 yet.

Dang. The 2.6.38-9 definitely doesn't fix it for me. It's reproducible

After using the test kernel for a while, I can confirm that the issue
still occurs with this kernel, it just takes more uptime for it to
occur. I'm now trying the solution proposed in #55 (turning off 'Sync to
VBlank') with the 2.6.38-8 (default 11.04) kernel, will report back.

Something blocks compiz randomly
I have Acer Extensa 5630Z with Intel integrated graphics chipset.
I am getting the same problem as described in the first post.
Bear in mind I didn't have time to check the replies yet, so I will get
back to you when I try solutions posted there.
The porlbem is that compiz hangs randomly,
Re #55, the problem recurred, but with less frequency. htop shows that
from time to time, both processors on my system run at 100% or very
close, and then all other tasks freeze, except compiz-related tasks like
shift-switcher.
I thought for a while that the problem got worse when I was doing
After installing kernel 2.6.39-1.6, I am no longer seeing this issue.
Additionally, I am unable to force-reproduce the bug with xset dpms
force off, which would trigger it reliably previously.
Am I correct to assume the kernel fix will be applied to the 2.6.38
branch as a SRU for natty-updates?
I think compiz hanging upon dpms off state, and compiz randomly freezing
during high CPU activities are separate bugs. . .

I've fixed the problem I had - at least I think so. After an extremely
frustrating day with an unusable machine (dual-processor, Acer desktop).
System / Preferences / CompizConfig Settings Manager / OpenGL
and then un-tick Sync To VBlank.
My machine came back to life. What a relief.

I have seen it a few times on mine too.
Dell M1330 with Intel graphics.
I'm considering to un-tick Sync To VBlank as mentioned above, as I have had
issues with clutterflow before.
The solution for that is to add
export CLUTTER_VBLANK=none
to /etc/environment

scrutiny revealed that my login password had been appended to my AP PSK.

No, it doesn't. This bug has several assignees, is full of debugging
information, already triaged, targetted and milestoned, so it doesn't
really make sense to mark it as a duplicate of a bug that has none of
those things (that would just create extra work for people) ;)
