Brightness keys are not working. When pressing these in kde plasma no brightness increase / decrease indicator is shown.
The brightness system itself is working: When changing the brightness using the plasma battery applet, the brightness changes as expected.

Changing to runlevel 3 showkey and evtest don't respond to pressing these keys. They only respond to other keys.
evtest displays
/dev/input/event1 is Video Bus
Here it displays Event code 224 for KEY_BRIGHTNESSDOWN and Event code 225 for KEY_BRIGHTNESSUP. But pressing the buttons leads to no response.
