I could temporaryly solve the problem. I used nvidia-settings to save the configuration into an xorg.conf and rebooted the system.
I get three (!) error reports, that the given configuration could not be applied (indeed, it did!).
I tested if, on the fly changing of the configuration is possible (toggle dual screen / single screen): it is not. Doing this applies to the given bug report above.
