Brightness not working asus laptop GL503VS linux

Hi everyone,
I’m writing here because I tried literally everything to get brightness working on my laptop but I didn’t get it. The brightness is locked at 100% and it’s impossible to change it. I found other topics too but without solutions…

It’s important to say that on windows the brightness is working flawlessly out of the box…

I have sys/class/backlight/nvidia_0 backlight device in sysfs. I added also the user to the video group.

What I tried (none of these worked):

  • Changed manually the value in the brightness file and actual_brightness
  • Changed brightness via brightnessctl, light and other utilities
  • Tried all acpi_osi and acpi_backlight kernel params
  • Added nvidia.NVreg_RegistryDwords=EnableBrightnessControl=1 to kernel params (Checked in the /proc/driver/nvidia/params file that is correctly enabled)
  • Tried everything in the arch wiki https://wiki.archlinux.org/title/Backlight https://wiki.archlinux.org/title/Laptop/ASUS
  • Tried other distros / drivers

My specs :

Laptop Model = ASUS GL503VS
Distro = Arch Linux (bug doesn't depend on the distribution)
Display Server = Wayland
Bios = v308 (latest available)
GPU = GTX 1070M
Nvidia driver = 565.57.01 (proprietary driver)
Boot manager = rEFInd

Here there are some files that could be useful:
/proc/driver/nvidia/params (1008 Bytes)
nvidia-bug-report.log.gz (1.2 MB)

I would be really happy if someone could help to solve the problem. Thank you!
I’ll wait for a response.
