Brightness adjustment broken on Intel Sandybridge on Linux #90

Open ThunderRuler opened 6 years ago

Currently cannot adjust the brightness/gamma of any openGL application (mostly games), such as Minecraft, Open Arena, CSS, Doom, etc.

As the bug is affecting other games it's probably a driver issue, btw it can be useful to know that the distro is Ubuntu 16.04 LTS and using drivers from Padoka's stable PPA does not fix the issue.

Some quote from glxinfo's output:

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.2.8
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL version string: 3.0 Mesa 17.2.8
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 17.2.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

Anyone with an Intel Sandybridge Mobile GPU who can try to adjust brightness on Unvanquished to try to reproduce the bug?
