Bug Description
Binary package hint: gnome-control-
Machine: Lenovo Thinkpad X201
Important(?) remark: I switched back to a previous linux kernel to write this report in a decent way, the collected information is therefore not accurate, the uname should be the newest kernel now used, not the one that is in the list.
Bug is critical - I cannot use my machine in any normal way with Ubuntu.
In the previous version of Ubuntu (10.64) the following problem did not occur - it all worked like a charm. After the upgrade my machine became virtually unusable due to the following video problem.
Details: by default Ubuntu 11.04 does not start in full resolution on my external display. Only a small square is visible in the middle of my screen. That is no real issue for me, however:
if I use Monitors (gnome-
- external screen goes blank (dark color, not off), mouse still visible and movable
- laptop screen is switched off (not dark color, really off) (thats good)
I cannot do anything, so have to wait until it automatically switches back to previous settings. However, this goes wrong as well:
- laptop screen joins the party: same as external screen now, also a movable mousepointer with a blank, dark colored, screen.
Machine is unusable from now on.
Hope you can solve this soon. I've tried it with 2 different installations of Ubuntu 11.04 on my machine - same problem. Thanks.

Hi Ardoban,
This is not a problem in gnome-control- center. It's likely to be one of the many problems with external monitors that afflicted Natty. Two quick questions before doing something with this bug:
1.) Does it still happen after applying all updates?
2.) If it does can you check if it happens when using Classic Gnome session?
