I can't change the brightness in Kubuntu 18.04. I tried to do it with the keyboard shortcuts (Fn + /) and in the Battery and brightness section in the Task Manager.

As just a simply workaround you can use the following command-line to set your brightness:

echo 255 | sudo tee /sys/class/backlight/*/brightness >/dev/null

Change the 255 value with one from 0 to 255 to move from min to max value.

  • I suppose you have some trouble with the display configuration, so to solve the issue from the root, you have to found the original problem. – maxwatt Apr 17 '20 at 20:00
