Description of problem:
It causes on my ThinkPad T410 with nvidia graphic card. I have two monitors connected - one the laptop built-in and the second one by VGA connected 22' Samsung. When change resolution by Control Center - Displays on the second one (Samsung) to the smallest one (800x600) and back to the origin one, the samsung monitor never wake up and the laptops one shows the desktop with some graphic fragments. I can move the mouse but cannot do anything more. Only possible way is to hold power button and shutdown the laptop by force..
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Have active two displays - one monitor built-in and the second one through VGA
2. Change resolution on the external display to 800x600, confirm by click "Keep this configuration"
3. Change back to the original resolution
The resolution should change
I was not able to reproduce it using DVI or intel graphic card..
Are you able to provide kernel logs from after this issue has occurred?
It seems it's fixed now, I'm not able to reproduce it any more with kernel-3.3.0-0.20.
Closing with resolution CURRENTRELEASE
