[Maverick] Crash when unplugging/disconnecting external screen

[Thomas Jacobsen]

I have a Thinkpad T61 with a GMA950 intel graphics card. The bug occours when having an external screen plugged in and wants to unplug it. If I just pull the plug I am garanteed a black screen and there is nothing to do than a hard shutdown. If I disconnects the external screen from the Monitor menu, it only crashes 50% of the times.

Thomas Jacobsen, 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 xorg-server 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.
