Comment 15 for bug 944736

Will do so - but to update -
took a little persistence or just happenstance but finally in a ubuntu session with current lightdm

gist of it is - tried the gtk-greeter to see if any difference, none, switched back to the unity-greeter
So went to a vt, installed gnome-shell, tried a login which worked.

Then tried a ubuntu login, this time got to a Desktop but no compiz/unity, tried a couple of times, same thing, xsession error about compiz 'crashing too quickly'

Tried unity-2d, this time it worked
Went back to a ubuntu session & it loaded without incident.

So I'm going to guess that on this install I'll now get past the greeter to a Desktop, though
i'd figure compiz may 'crash' some of the time, will not the rest (no .crash is created

Will give it a few tests though could be more useful to do a fresh install & see if this is an accumulated behavior or the current state
