This article discusses how to adjust the brightness of a Linux screen. It explains that since the user is using DWM, which does not have a graphical brightness adjustment feature like KDE, they need to manually adjust the brightness. The article provides commands to check the current backlight control and brightness, as well as a command to modify the brightness.

Check what controls the current backlight:

It's usually intel.

ls /sys/class/backlight

Check the current brightness:

cat /sys/class/backlight/intel_backlight/max_brightness

Modify the brightness:

echo 5000 | sudo tee /sys/class/backlight/intel_backlight/brightness
