Bug Description

This is a regression of Bug #275285. The problem was caused by 965GM not working correctly with framebuffer compression (FBC).
In #275285 the solution was to disable FBC in xserver-xorg-video-intel code on 965GM by default (http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=d24010b7b3f2419beb40dc5ae1e8aeb3e04b5a93) and add UMS option to enable it if needed. Since UMS were removed from Intel drivers and replaced by KMS now there is no user configurable option for FBC anymore. And disabling FBC by default was removed too along with UMS code (http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=b9b159c49854d8d9d2207946bb583537bb0d48d6). KMS enables FBC for this chipset by default and there is no configurable setting that I could find to disable it. The best solution that I could come up with was to rebuild kernel with the attached patch.

Please suggest a better solution if you know one or incorporate this patch into kernel.

Hey kolyuchiy,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

I tried to run a test app that was provided in https://bugs.freedesktop.org/show_bug.cgi?id=16257#c16. The bug is not reproduced anymore with all recent updates from oneiric. It can be closed now.

Please try to run the test program from https://bugs.freedesktop.org/show_bug.cgi?id=16257#c16. That way we will know if it is the same bug or another bug with similar effects.
