It looks like XAUTHORITY isn't set, which means that you probably don't 
have "xauth" in your path (it's probably not installed).  Install 
xorg-x11-xauth, and then log in again.  On your next login, sshd should 
create the XAUTHORITY file.

Having said that, if xauth is missing, you should see an error stating 
that in the output of "ssh -v", which you don't.  That's very odd.  I'm 
fairly certain that the problem is the missing XAUTHORITY variable, I'm 
just not sure why it's missing.

If xauth is present, try creating a new user on the system, and see if 
you have the same problem when you log in to that account.
