https://bugs.freedesktop.org/show_bug.cgi?id=99291
Bug ID: 99291 Summary: R9285 amd-staging-4.7 bad gamma since drm/amd/display: Implement gamma correction using input LUT Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: adf.lists@gmail.com
R9285 git amd-staging-4.7 xserver 1.18.4
since da3877a82a8a9375f47334cffd375c795d7a0f8c drm/amd/display: Implement gamma correction using input LUT
initial x gamma will be far too light.
Turns out that although xgamma reports 1.0, doing
xgamma -gamma 1.0
corrects the issue

--- Comment #2 from Alex Deucher alexdeucher@gmail.com --- There is a gamma fix in the latest amd-staging-4.7 branch I just pushed. Does that help?
