Comment 12 for bug 2052489

I've also tried the kernel option apparmor=0 and can confirm that it made no difference; still got to a black screen and no GUI.
I have not had time to try the move to gdm instead of lightdm but may also try that later.

Can I assume this problem occurs on a bare metal install as well as on a virtual install? I don't have a spare area to try that at the moment.
