Sddm worked as expected, not to mention its veeery slow interface (for 
that nvidia drivers can be blamed, but whatever). The black screen 
appeared after logging in.

There were three choices for the session. By default plasma was 
selected, this was the one that gave me the black screen. Others didn't 
plain work (returned to sddm).

Thanks for the hint, it's a good idea, I also had a couple of times when 
a working X would be helpful but failed to start due to kde related issues.

As for the new plasma stuff, I have almost all possible kde packages 
updated to 5.x (unstable), with the exception of kdm, kwin, settings and 
several others. My emerge of plasma-meta replaced these and additionally 
installed 78 packages, the larger half of which wasn't kde related 
(ruby, . What could have caused a black screen, I have no slightest idea 
and since it prevented me from work I gave it up.
