[Arch Linux][Hyprland][ASUS TUF] Brightness control not working on AMD + NVIDIA hybrid laptop

Hey guys, I need help with brightness control on my ASUS TUF laptop running Arch Linux + Hyprland.

My laptop has:

  • AMD iGPU
  • NVIDIA RTX 3050
  • Hyprland (Wayland)
  • Arch Linux

The brightness keys used to work before, but now they don't change the actual screen brightness anymore.

Current situation:

ls /sys/class/backlight

returns:

nvidia_wmi_ec_backlight

When I run:

brightnessctl -d nvidia_wmi_ec_backlight set 50%

it says brightness changed successfully:

Current brightness: 100 (50%)
Max brightness: 200

but the physical screen brightness does NOT change at all.

I also checked dmesg and got:

[drm] Skipping amdgpu DM backlight registration

I tried:

  • brightnessctl
  • Hyprland keybinds
  • acpi_backlight=native
  • amdgpu.backlight=0

But adding those kernel parameters caused Hyprland to stop launching and I had to revert them from TTY.

Has anyone fixed this on ASUS TUF laptops with AMD + NVIDIA hybrid graphics under Wayland?

Any help would be appreciated 🙏Hey guys, I need help with brightness control on my ASUS TUF laptop running Arch Linux + Hyprland.My laptop has:AMD iGPU
