["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Minh Ha Doung, could you please confirm this issue exists with the
latest development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [gm45] Dual head corruption on 2.6.37 lucid backport

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Lenovo X301 laptop, 4G ram, Intel(R) Core(TM)2 Duo CPU U9400 @
  1.40GHz. Intel GM45 Express graphic chipset, Kubuntu 10.4.1 LTS Lucid
  32 bits, Xorg driver "intel"

  # uname -a
  Linux wall-e 2.6.37-12-generic-pae #26~lucid1-Ubuntu SMP Wed Jan 5 22:54:38 UTC 2011 i686 GNU/Linux

  # version.log
  Ubuntu 2.6.37-12.26~lucid1-generic-pae 2.6.37

  Symptoms:
  When starting X with the external screen attached to the VGA connector, I can't type anything in the login/password at the kdm greeter dialog. I can switch to VT1. Then I can kill kdm. Restarting kdm gives fatal error with technical messages about gem.

  Starting without the external screen is okay. If I plug the external
  screen and start using it (xrandr), the cursor becomes corrupted when
  it is inside a konsole window on the laptop screen, but gets back to
  normal outside this window. Then X freezes after a while.

  Working single-headed without plugging the external screen at all is
  fine so far.

  Previous versions  2.6.35 and 2.6.32 did not do this
  Previous version 2.6.37-11 already had the problem.
