Anmar Oueja, thank you for reporting this bug and helping make Ubuntu better.
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? Can you try with the
latest development release of Ubuntu? ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command from a Terminal
(Applications->Accessories->Terminal). It will automatically gather and attach
updated debug information to this report.
apport-collect -p linux <replace-with-bug-number>
Also, if you could test the latest upstream kernel available that would be
great. It will allow additional upstream developers to examine the issue.
Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the
upstream kernel, please remove the 'needs-upstream-testing' tag. This can be
done by clicking on the yellow pencil icon next to the tag located at the
bottom of the bug description and deleting the 'needs-upstream-testing' text.
Please let us know your results.
Thanks in advance.
** Description changed:
- I believe this is linked to Launchpad bug #622420
+ I have a ThinkPad X201 with Arrandale graphics. When I plug in an
+ external screen via the docking station DisplayPort or directly to the
+ laptop (undocked) via the VGA port, I can manage my dual screen with no
+ issues at all with one exception. If I either unplug the external screen
+ or if I go to gnome-display-properties tool and turn off the laptop
+ screen. If I do that, the laptop screen goes black and flickers (looks
+ like X is trying to recover or something) but nothing happens. After 20
+ or so seconds, the system locks up completely.
+
+ Please note that this was happening since Alpha 2 of Maverick but I
+ chose to wait thinking the latest Xorg release will fix this. I would
+ like to note that this problem does NOT happen with Lucid so it is an
+ Intel driver regression.
