Hmmm... I'll try to set $DISPLAY on the n800 xterm, rather than SSH.


But! Remember that xhost+ is a bad idea, except in a controlled environment! Xauth is the way to go, but is a little more complex.

The beauty of SSH forwarding is that it is supposed to handle the $DISPLAY variables and "faking" xauth, but in this case it's not working under Xorg's X server, but is working under a Windows X server. Very strange.
