Comment 6 for bug 692677

With a fresh install of iso available today on a laptop, (dell 1330, nvidia 8400m GS), basically same the same thing -
Desktop login to unity, crashed window dec., then nvidia-settings
Classic login to gnome-panel, initially just froze up on the X Server Display Confirmation menu, after applying the small set of updates ( mainly gnome-panel and indicator package updates), it works fine

Returning to Desktop login still the same crashes.

Employing the second way to run unity - login to Classic with the unity plugin enabled - it works fine
So the Classic login is good with either the unity or gnome-panel interface
The Desktop login is a no go.

(- this is not the only instance where a Classic > unity login is better behaved than a Desktop > unity login.
I think I've restarted, logged in/out more in the last couple of weeks than in the last couple of years altogether...
