Yesterday I installed nvidia driver 355.11 update from the "ubuntu fresh graphics"-PPA and the problem seems to be fixed. I can switch via "prime select" and login via light-dm works fine on nvidia. There's only one flaw beloging to screen postioning but this is a new issue and should not be mixed with this problem. For me this issue could be marked as fixed and closed.
