Bug Description

Binary package hint: xserver-xorg-video-intel

To reproduce do following:

1. Connect external monitor to VGA output.
2. Launch gnome-display-properties and enable external monitors.
3. At this point, both LVDS and external monitor should be working just fine.
4. Using gnome-display-properties, turn off LVDS.
5. At this point, the image in the external monitor looks like [1].

Note that this bug report was filed *while* LVDS was off and VGA1 was on flickering as per [1]

3. Disabled LVDS: ERROR showed as previously discussed (flickering)
4. While having the external Monitor flickering and LVDS off (and connect through remote Desktop) i filed the bug with:

Hi Andres,

There have been a bunch of bugs filed about Arrandale with external monitors causing trouble. I've only seen one other bug where a flickering screen resulted (lp #758785), although the symptoms differed. I posted a few random ideas to that bug report to test out, I'm going to post a couple other random ideas here for you to try:

a) I've prepared a PPA which adds a DPMS on to the X driver. Please install this and then see if you can reproduce the bug:

https://launchpad.net/~bryce/+archive/elderberry

b) Upstream is staging several patches including some Ironlake/Arrandale fixes to one of their kernel drm branches. It would probably help them if you could test these before we forward this bug report to them. If you wish (and know how), you can build the kernel manually: http://git.kernel.org/?p=linux/kernel/git/ickle/drm-intel.git (branch drm-intel-next-proposed). If you don't know or don't wish to manually build the kernel, I'm asking the kernel team to start doing automatic daily builds of this tree; stay tuned and there will be .debs available of it probably within a day or two.

Hi Bryce,

I'll test (a) later today, but build the kernel tomorrow (or at least try, I do know how to do it). I'll post the results as soon as possible!

Thank you!

Bryce,

a) Didn't work.

Gonna build the kernel now.

Cheers,

Andres, to save you some kernel building effort, we're now doing daily snapshot .deb builds:

Hi Bryce,

Just tested the kernel 2.6.39-0.4~20110419 and the issue is no longer present!!!!

Cheers,

Andres, great news! Are you interested in doing some further testing to help narrow in on what patch in that kernel provided the fix?

Directions on doing a git bisection search are available here: https://wiki.ubuntu.com/Kernel/KernelBisection
