From what I've read so far the reason behind that is in missing support of features used in Unity by Nvidia drivers.
I could try to switch to intel driver just for the sake of the test, but decided it's not worth the effort.

So far it's unclear when NVidia will properly support U8, at least I didn't find any specific date

I would recommend just purging the hideous nightmare that comprises Unity 8 entirely using sudo autoremove --purge unity8 which will uninstall all the main unnecessary components of the Unity 8 preview. I'm running 16.10 perfectly fine without it.

The Unity 8 desktop preview is completely unusable on my high DPI laptop display, and looks positively awful. So yes, it's a nightmare. My main desktop also seems to change in scaling whenever I switch back, so I figured it was useless and decided to free up some memory by just purging it. Mostly because...it's awful. – Nicholas Stommel Oct 15 '16 at 07:33

How would OP do that if he can't log in? -1 – David Foerster Oct 15 '16 at 21:48
Use the rescue shell on startup by booting into recovery mode. – Nicholas Stommel Oct 16 '16 at 23:02
Won't there be no desktop at all then? – TheWanderer Oct 16 '16 at 23:02

Um...no. Just uninstall the problematic Unity 8 preview. The normal Unity 7 used in the main desktop will be unaffected. The Unity 8 preview is buggy and incomplete as hell. – Nicholas Stommel Oct 17 '16 at 01:42
