Unable to login to standard ubuntu session

[James Page]

I'm unable to login to the standard Ubuntu session; one of two things happen

a) background appears but nothing else
b) returned back to login screen

Ubuntu-2d is fine.

Guest with standard Ubuntu session appears to be OK as well.

Was working find until I rebooted this morning after apply most recent updates to precise.
