Comment 11 for bug 918769

Forwarding this bug from Ubuntu reporter Jerome Tournier:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/918769

[Problem]
X session starts up fine but the screen blinks every ~10sec. Also displays black screen.

Booting with nomodeset makes issue stop.

Also tested mainline kernel 3.3.0-030300rc1_3.3.0-030300rc1 and (I think) drm-next and drm-intel-next.

[Original Description]
I can't actually manage to have X working correctly with my Vostro 360.
The X session start but the screen blink every ~10s (and stay back most
of the time).

I found a lot of people having similar problem, but no solution can be
applied to my case.

X logs for Ubuntu 11.10 (i386 but same issue for amd64):

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
I will attach a kernel and Xorg dump.

The only way for me to have correct resolution (1920x1080) was in using
the Live CDROM of elementary OS (based on Ubuntu Maverick 10.10) which
use:
- linux-headers-2.6.35-28-generic 2.6.35-28.49
- xserver-xorg-video-intel 2:2.12.0-1ubuntu5.2

.. but once the system installed, the black screen problem come back. I
can't actually undestand the difference between the live OS and the
installed one (after the installation, the kernel is slightly different;
but after installing exactly the same than the one used in the live CD,
the problem persist).

I also tried other Ubuntu release, even the latest Ubuntu 12.04 precise
(alpha version): same issue.

Booting with nomodeset helps also, but lead to a low resolution.

Any idea on what could explain that eveything is working correctly with
the livecd, and nothing once the system installed ?

More generaly, how can i help to have a working solution ?
