Hello. I have a laptop with only Nvidia graphics, and after I’ve installed the system I could change the screen brightness. However, after running pacman -Syyu and rebooting, brightness slider does nothing. What can I downgrade to make it work again?
Welcome here, @btwiusearch23,

Have you tried
as kernel parameter in /etc/default/grub already?
Or some of the variations?
