xfce4 install

[thufir]

As per:

http://www.psychocats.net/ubuntu/xfce

I've installed xubuntu-desktop (as well as xfce4) but cannot log into 
xfce, it just bounces me back to the login GUI.  LXDE works fine.

Also, when I search for "xf" packages, everything listed shows as 
installed.

Is there a log which would be useful?

I poked through /var/log/syslog but nothing seemed obviously related to 
xfce to me.



thanks,

Thufir
