description |
Backlight does not change. Neither with the keys, nor with the slider. Values in /sys/class/backlight/amdgpu_bl0/brightness do change. However without effect on the actual brightness of the screen, which seems to be stuck at maximum brightness.

[Test]
Verified on hardware, backlight brightness works fine.
[Where problems could occur]
It may break backlight control on AMD platform. |
