When i press the "Monitor Brightness Up" or "Monitor Brightness Down" it activates a second time some seconds or even minutes later.

journald looks like this:

Code: Select all

The first activation(18:17:35) was intended, the second(18:19:20) not. I have no idea what could be wrong. It was like this already after the installation of Kubuntu. It seems like it activates directly after another event (in this case cron.daily) gets executed.

I use Kubuntu:
