I'm getting all-black desktop too. But it's literaly all black. Even if I DISPLAY=:0 mplayer video_file.mp4, that video does not show up.
Once I caught a glimpse of a perfectly well started KDE5 session, but that happened when I was killing it.
Sounds like there is some kind of a "black curtain" over everything? WTF
