Thanks for your help!
I have installed version 3.6.2. again and started testing. Of course, the standard driver in 3.6.2. gave still the same problem as above. I have tested the drivers you give, and found the following results: Version 16a: Works perfectly. Version 16b: Works perfectly. Version 16c: Gives the following error in the log: Dec 1 15:28:18 raspberrypi systemd[1]: Starting Graphical Interface. Dec 1 15:28:18 raspberrypi systemd[1]: Reached target Graphical Interface.
