Brightness button doesn't work, xbacklight doesn't work either

I tried to increase my screen brightness using the brightness keys but it doesn’t work. Then I tried running the xbacklight -inc 5 command but that didn’t work either.

My laptop has both intel and Nvidia GPUs but I am using Nvidia only to reduce screen tearing. So how do I have intel_backlight?!

~ ls /sys/class/backlight

Is this installed?

By default Bspwm edition uses xbacklight to control brightness. This works only with intel cards. Your Nvidia card may be inducing some friction.

Try what xircon suggested.
yay -S light to install the package.

Then try running following commands.
light -A 5 to increase brightness.
light -U 5 to decrease brightness.

Please report if these work or not.
