I have a beamer. Since installation of kubuntu-15.04 I can't log into my account if the beamer is connected. The kubuntu splash screen show up alright, but takes a bit longer to complete, then I am dropped into a black screen with a (movable) mouse pointer.
If I disconnect the beamer during startup, I can login.
