It seems that the driver was somehow not installed. But it "was" definitely installed. May I have uninstalled it accidently. So I have re-installed it.

I can manage to see 1 screen, which is plugged via the docking station, in the Ubuntu GUI display settings. I had also tried

with no visible result for me.
But now I can see at least 1 screen from 2 screens plugged in the docking station there. If I plug the other screen directly on the laptop, I can manage to get my two screens getting a signal.
The screen, which is plugged on the docking station, is switched off by default Ubuntu's display settings (the GUI). I can switch it on in the display settings and then it "kind of" works.
What means "kind of"? The mouse-cursor on this screen is slow and sometimes it takes a few seconds until I get feedback. The mouse coursor "hangs" then. So the functionality is not working properly.
After I reboot the system, I need to execute the console commands again and switch on the screen in ubuntu's GUI display settings again.
Well, something works not properly. I have created the logs-archive again and attached it. What is this KMU? Is there a chance to get the screens working properly or must the driver be modified?
P.S: If I plug the screen off, which is plugged in on my laptop, the screen which is plugged in into the docking station reacts quicker. This hangs and slowness disappears then. It seems the system cannot handle one screen directly in the laptop's HDMI port and one screen plugged into the docking station in a "quick reacting" way.
I have also tried to plug in the 1 screen on the docking station into the other port of it. But only 1 specific HDMI port from the docking station works. I have tried all xrandr options which I have mentioned in this post.
