I had problems with the brightness once I'm using 2 monitors

I used script to set the brightness


and I have this file

in 2 directories
![]()
and
![]()

and till now the brightness script not working with the OS startup
and now I got another problem that after suspend the brightness level reset to max
I searched and tried to fix and in the directory of /sys/class/backlight/ I have these 2 folders

in the asus-nb-wml folder the max_brightness 10
and it's all files read only so I can't change anything
same for brightness
but in the intel_backlight
brightness & max_brightness 5273
and also all of it read only
