Brightness not working asus laptop GL503VS

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.

Edit: Silly me didn't read your post closely enough. You already tried that...

Maybe not the answer you seek out, but brightnessctl does work for me. I implemented it just yesterday. Should work for X11 and Wayland.

To controll brightness of your display:

brightnessctl set 10%-
brightnessctl set +10%

(command either manually or bind them to the matching key)

You can read more about it in the manual. I assume you've already read the Backlight wiki page.

Re: Brightness not working asus laptop GL503VS

brightnessctl -l

lists all devices with available brightness controls. Is there an entry present that matches your display?

For me it is:

Device 'intel_backlight' of class 'backlight':
	Current brightness: 451 (30%)
	Max brightness: 1515
