Hi,
Basically neither version is happy doing this. (Then don't do it!).
12.04 will crash on reboot with the screen showing...

I ran recovery mode and appended rw init=/bin/bash to the end of the linux line so I could get around that aggrevating enter root password - for maintenance or Control-D to continue and the root password always fails.
Anyway, I checked the xorg.conf in 12.04 and the nouveau driver was still listed. I tried changing to nvidia but no joy, LMCE does reboot but hangs at oribter generation - I think.
14.04 booted with an error message, then rebooted and stalled @ orbiter generation, again, I think.
This is the log activity...

This is from 14.04 but it appears exactly like 12.04 messgaes.
14.04 logs complains about module license 'NVIDIA" taints kernel. Signature and/or required key missing - tainting kernel.
Cheers.
