Hi
I have a laptop with Nvidia/AMD GPU (below more details/logs)
If I set discrete mode (only NVIDIA) the brightness works (* adding nvidia.NVreg_RegistryDwords=EnableBrightnessControl=1 to the kernel cmdline)
If I set Hybrid mode (AMD default and NVIDIA on demand), I can’t adjust brightness no matter what I’ve tried
Things didn’t worked for me (kernel cmdline):
amdgpu.backlight=0
acpi_backlight=video
acpi_backlight=vendor
acpi_backlight=native
acpi_backlight=none
Right now I’m running in discrete mode to have brightness control, but I would like to run in hybrid mode
Do you know what I’ve missed to try? or there’s a bug in the current driver with this board?
I’ve checked this post (haven’t tried it yet), but is just a workaround and last resort. It shouldn’t be that way.
Thanks in advance
