I'm using Nvidia prime with a Quadro K1100M card.
When I switch from intel to nvidia, then after booting I get a black screen about 50% of the times. I can't but switch to a virtual console by pressing [Ctrl+Fn] and then reboot. If I'm lucky, then the normal Kubuntu login screen appears, otherwise I get yet another black screen and have to reboot again.
