Re: using Mathematica and Geomview on different machines

[slevy]

OK, let's see.  The problem is that OOGL.m, when it starts the remote
copy of Geomview (on the Sun in this case), sets the DISPLAY environment
variable to just ":0".  This forces geomview to display on the same machine
where it's running.  This is normally the right thing to do... but not in
your case.

So try this.  Here's a patch to the file OOGL.m which allows Geomview[]
to accept an "XDisplay" option.  So you could say

    SetOptions[Geomview, XDisplay -> "your_X_terminal:0"]

and then use mathematica+geomview as intended.

I think it should suffice to put a copy of the modified OOGL.m in
your current directory when you invoke Mathematica.

Here's the patch, in unidiff form.  If you want the complete file,
I could send that instead.
