I have this problem, too, but on a ubuntu SERVER system. Today I upgraded from 10.04 to 12.04 and my machine does not power off most of the times. It's frustrating. With 10.04, there were no problems. I used this machine for nightly archiving data and for nightly backups of my server, with WOL enabled and automated shuitdown. It worked perfectly a very long time, until today.
I guess, this problem has nothing to do with any desktop environment. Maybe it is kernel-related?
My system is an ASUS E35M1-I DELUXE.
