That's really a shot in the dark. What I typically do is ssh -X user@hostname. That way you don't have to set the $DISPLAY on the remote host. It takes a bit more overhead, but since it's symmetric encryption, it's usually not very significant. But I have never tried what you are doing, nor am I set up to reproduce it here. I run Mathematica (for Linux) on the only system I have that dual boots, and could handle the load it would require. Can you run other java apps from the same login? It looks like the GUI-Kit Java process is not being passed the environment that Mathematica is running in. If that's the case, I don't believe my suggestion of using SSH will work. Nor will the xhost+. -- The Mathematica Wiki: http://www.mathematica-users.org/ Math for Comp Sci http://www.ifi.unizh.ch/math/bmwcs/master.html Math for the WWW: http://www.w3.org/Math/
