Hi, thanks for you promptly response, unfortunately only now I had the
time to check the things above.

Meanwhile I had to reinstall ubuntu 16.04, its the default with Unity, same
behavior.
When I've started the newly reinstalled system, it seemed to work well, the
dual display, after a reboot or two, it stoped working.
The login screen works well and displays with dual display when I
restart the laptop, but after I login it crashes, and it seems to
restart the graphic environment/xserver maybe ...
I can post some additional logs.
