It worked indeed. Result attached.

So X selects correctly the right display (and I have the small drawing on the screen after switching X on that show a displayport icon as when I start kdm) before evrything goes dark and monitor led turns off.
So I bet sddm or the sddm greeter greeter is at fault. What else can I do to help fixing?
