I’m having an issue in Fedora 41 where my brightness control can’t be accessed by my Intel iGPU.
Brightness control works correctly when booting into AsusMuxDgpu mode via supergfxctl --mode
, but when booting into Hybrid mode, the brightness slider stays controlled by the Nvidia dGPU. I figured this out by running brightnessctl
while in Hybrid mode and getting this output:
>sudo brightnessctl
Device 'nvidia_0' of class 'backlight':
Current brightness: 48 (48%)
Max brightness: 100
I have tried manually changing the target for the brightness profile via brightnessctl -d intel_0 set
, which also didn’t work.
This has been an issue since I installed Fedora 41 fresh after moving from another distro.
Some other details that might be relevant;
- Running Fedora 41 and Windows 11 Dual Boot
