So,
I tried a lot of things...
installing nvidia current and doing xconfig and big mistake.
Tried just the current driver and renaming nouveau to nvidia and big mistake.
Tried changing nvidia back to nouveau, big mistake.
Tried nvidia site download driver, you got it, big mistake.
Tried rebooting (holding down shift) to get into AVWizaard, another mistake.
On this snap, even before/after updates, etc. the answer seems to be, "Don't mess with the nouveau" and don't try to re-run AVWizard.
Cheers
