**What should i do? Where can i get the logs that are being using to investigate whats going on

Answer 1

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

Answer 2

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.
