Sure - but kde has no option for virtual desktop.
I can drag and drop monitors, but they remain 3 different desktops (in my 
case). 
... and rotation is applied AFTER login, so login screen is weird.

I'm looking for a way to get one single desktop, that spans 3 monitors and I'd 
prefer a way that this desktop is available before login (just like xinerama 
does)
