unity8 desktop boots to black screen on yakkety daily fresh install

[ventrical]

All new hard installs of yakketty amd64 with unity8/libertine (non-ppa) will boot to black screen on both machines with nVidia and Intel graphics adapters. This makes it virtually impossible to test current/dailys w unity8.

Regards..
