Kai Aeberli, 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 xserver-xorg-video-intel REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is
already available, doing this on a release prior to the development one
would not be helpful.

Thank you for your understanding.

Title:
  [i945gm] external screen does not work consistently

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: xorg

  When plugging in an external LCD Screen (LG Flatron L1915S) into my
  Thinkpad R60 Laptop, it works only very inconsistently. What happens
  is that the screen shows for a split-second and then goes dark.

  This behaviour occurs sometimes when resuming from hibernation, or
  just when hotplugging the screen. I even had it when booting up with
  the screen connected. I am finding it difficult to pinpoint the exact
  conditions of the error.

  Further, when it does work, as soon as I plug in the external screen,
  all desktop effects are disabled, and I have to enable them again.
  Also, Desktop effects don't work when displaying on both screens.

  The bug report command was run at a time where the external monitor
  was working.
