Description of problem:
After updating from F15 to F16, my external monitor stopped working.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. try to set up external monitor in F16
Tried nv, nouveau even nvidia (the official binaries with IgnoreABI) and none of them works. The monitor sometimes turn on with nouveau, but the image is mangled - seems like wrong refresh rate and after a few secs it turns off.
Working external lcd.
My GPU is:
01:00.0 VGA compatible controller: nVidia Corporation GT218 [NVS 3100M] (rev a2)
