how to make brighness control gui work ?

I am using arch + cinnamon, I found that when I change the brightness in the system tray, it does not work,

because the slide bar of brightness is binding with the file of /sys/class/backlight/nvidia_0/brightness  (nvidia),

when I change the brightness value in /sys/class/backlight/amdgpu_bl2/brightness (amdgpu) , it works.

how can I make the brightness slide bar bind with the right file /sys/class/backlight/amdgpu_bl2/brightness ?
