Brightness in WM

Brightnessctl only works as root

Check to make sure you have the right udev rules installed. The udev rules are found at /usr/lib/udev/rules.d/90-brightnessctl.rules. If it is fine, try adding yourself to the video group. I think this is necessary for light as well. REBOOT is neccesary.

sudo gpasswd -a <user_name> video
