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

Steve Newcomb, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, 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:
  external monitor no longer works

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I updated my system, a Lenovo X220, this morning.  Upon rebooting, the
  external monitor would not work.  It flickers a lot of mainly-green
  gibberish, and it is unusable.  The internal LCD screen in the
  notebook still works, but not when the external monitor is connected.
  The external monitor is a Samsung 1920x1600.  I rebooted the machine
  again, this time selecting Linux 2.6.38-11.  Now the external monitor
  works properly, just as it used to.  Upgrading the Linux from -11 to
  -12 is clearly what broke the system.
