sudo passwd root -- operation not permitted

[Brian Cluff]

Sounds like you don't have write permission to the joe home directory. 
The graphical environments need to be able to write to log in, while the 
terminals don't.

My guess is that your login User ID and Group ID from your old home 
directory didn't line up with the new install, or your drive is mounted 
read only.

I would login as joe to an console via ctrl+alt+f1 and then do:
sudo chown -R joe.joe /home/joe

That should fix you right up.
