Not that it should matter but I'm not using ssh. Just using xterm. As
I have stated, I have set the DISPLAY environment variable on the
remote machine to point my local machine using both machine name and IP
address. Have also tried xterm -display mymachine:0.0. It's not just
xterm but any application that is trying to bring up a window that says
it can't open the display on mymachine. Plus I have performed an xhost
+ on mymachine which is supposed to allow clients from any host to
connect.
