intel kms breaks xgamma
Last modified: 2014-03-16 23:17:33 EDT
Description of problem:
After loading the intel KMS support with 'modprobe i915 modeset=1', xgamma has zero effect on the display, either from xorg.conf directives or from the commandline. The server and the utility think the gamma is adjusted, but the display does not change.
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
Version-Release number of selected component (if applicable):
Well, only booted once so far, but there's no reason to think it isn't repeatable.
Steps to Reproduce:
1. Load modesetting driver
2. Start X
3. Attempt to adjust gamma

No, it's fine, I know exactly what's broken.
xorg-x11-drv-i810-2_6_0-6_fc11 should fix gamma again.
