I believe that X on Ubuntu does things with xauth such that merely setting
xhost is insufficient; for example, if you log in to your desktop machine
remotely, setting DISPLAY=:0 won't let you start X applications. You'll
probably need something like ssh -X that forwards the local connection.
You can also try copying over the file in $XAUTHORITY and setting that
variable in your remote session, but that's pretty hackish.
