Bug Description

Binary package hint: xorg

Dual screen over VGA is no longer working for me under Natty. It used to work fine under maverick, but since the upgrade it just shows corruption/flickering screen. Whenever I'm using one screen it is working fine, and when I plug in my second screen my main (internal laptop) screen turns itself off and the external monitor keeps flickering at high frequency, showing random colours and sometimes little pieces of background. It doesn't matter whether the monitor is plugged in at boot or not. I have reasons to believe that the intel driver or xorg causes the problems because the GRUB and the login screen work both fine on both screens at the same time. As soon as I'm logged in this behaviour shows. It also doesn't matter if I'm using classic GNOME or the Unity interface. Xorg.0.log and dmesg are not showing any errors.

Also, can you try temporarily uninstalling ia32-libs and reproducing the issue, to rule out that as a possible suspect? (We had a bug on arrandale x86_64 recently that we believe was due to an old mesa in ia32-libs, but that should be fixed now.)

I can also confirm this bug. Hopefully it's the same

Happens on Lenovo T410 with Intel(R) Core(TM) i5 CPU M 520

Some things that are not working:
1. Plugging in external monitor makes primary monitor (laptop) go black and external monitor is a bit shifted + flickers in color similar to background.
2. Pressing ctrl+alt+f1 and then trying to go back with f7 doesn't work, only boot console output is shown.
3. After switching monitors with keyboard shortcut (fn + f7) screen goes black and only mouse is visible or nothing is visible at all.

Marten and Marius, would you mind attaching a photo showing the corruption you see when reproducing this bug?

Also, I have a suspicion this might be dpms related. After reproducing the bug, can you try issuing this command to see if it makes any difference?

xset dpms force on

If it does, I may have an idea for working around this.

dpms did not solve the flickering problem.

It may be another bug but after trying to switch modes without dpms screen goes black and only mouse is shown. On laptop monitor, on external monitor, and flickering mouse on external monitor (a little block flickering and everything else is black)

After I did dpms force on I managed to get normal extend view (i guess without dpms on i was able to get it too, but only black screen + mouse). I also did manage to get clone working properly. And next mode (probably external monitor only?) was the flickering one.

I also want to mention that I got crashed program errors with dpms force on saying that compiz has crashed.

Mm, alright well that's some progress.

"black screen with mouse" is almost key words for "GPU lockup". Check
your dmesg when it's in that state for error messages (or just post here
and I can look for you). Also snag your
/sys/kernel/debug/dri/0/i915_error_state file, which can have error
codes in this case.

Since the dpms command appears to have some effect (even though not a
full fix), try this PPA which adds a DPMS forcing functionality to the X
driver.

It's probably not gpu lockup because I was able to move mouse and see cursor move.

I attach dmesg output and syslog output after switching screens and restarting gdm.

Did you get a chance to test the elderberry PPA I posted?

After that, one other thing I'd like you to test before this gets forwarded upstream, please install the drm-intel-next-proposed kernel here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next-proposed/

Reboot, then reproduce the problem. Run 'dmesg > dmesg.txt' and attach dmesg.txt and /sys/kernel/debug/dri/0/i915_error_state to this bug report.

Marten, I'd particularly like your feedback with this data, since you're the original reporter for this bug report.

I can't reproduce the problem with this kernel.

@Marius, thanks. Would you be willing to do some additional testing to help narrow down what patch in that kernel provides the fix? If you do, then there is a chance we can get that patch added to the kernel in an SRU.
