Title:
kernel Patch to Fix Low and Inverted Brightness Value
After reviewing the 6.8.0-53.55 proposed (main) kernel for Noble which
came out 10 hours ago, there are already present "drm/amd/display:
Validate backlight caps are sane" and "drm/amd/display: Allow backlight
to go below `AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`" in its changelog. It will
be in 6.8 next u
drm/amd/display: Allow backlight to go below AMDGPU_DM_DEFAULT_MIN_BACKLIGHT
The issue with panel power savings compatibility below
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT` happens at
`AMDGPU_DM_DEFAULT_MIN_BACKLIGHT` as well.
That issue will be fixed separately, so don't prevent the backlight
brightness
The 2 patch above is available in mainline kernel 6.11.3
