Can't adjust screen brightness of Legion Y540-15IRH-PG0 in Manjaro (Linux) with using Nvidia GPU

2019-10-31, 8:40 AM

Hello All,

 

I have installed Manjaro linux on my Legion Y540-15IRH-PG0. I'm using the discrete graphics option (GTX 1650).

However, I'm unable to control screen brightness with using Nvidia GPU. It stays at max brightness.

 

I'll really appreciate any help on the same.

Thanks in advance for your help.

 

Regards,

Legion_User_007

Got it solved by editing /usr/share/X11/xorg.conf.d/10-amdgpu-nvidia-drm-outputclass.conf

 

Section "OutputClass"
    Identifier "nvidia"
    MatchDriver "nvidia-drm"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
    Option "RegistryDwords" "EnableBrightnessControl=1;" # Add this
    ModulePath "/usr/lib/x86_64-linux-gnu/nvidia/xorg"
EndSection

 

After adding the option string and restarting, it works... Finally!
        Option "RegistryDwords" "EnableBrightnessControl=1;
