I am having some trouble with the interaction between Mathematica 2.1
on an HP 9000/750 and a HP 700/X X-terminal. In a nutshell, all graphics
commands cause the X-terminal to crash. Example:
Mathematica 2.1 for HP 9000 RISC
Copyright 1988-92 Wolfram Research, Inc.
-- Motif graphics initialized --
In[1]:= Plot[ Sin[x], {x,0,Pi}]
Out[1]= -Graphics-
In[2]:=
At this point, after about 10 seconds the X-terminal totally locks
up and I have to power-cycle it. I see no sign of a graphics
window trying to appear. When I rlogin back in to the HP9000,
I find a 'motifps' process using 'ps' with about 5 seconds of cpu
consumed.
Perhaps it is relevant to know that although the server code for
the X-terminal and its fonts are loaded from the HP9000, the xdm
session is initiated from a Sun 4/280. So the Mathematica session
above was started after a rlogin to the HP.
An NCD 17C X-terminal under the same circumstances (except the
server code and fonts are tftp'ed from the Sun) works flawlessly.
So does an NCD 17C running Xremote software over a serial line.
Also, I have experienced no graphics problems (ie: xv, vuehelp,
architect, etc.) running the HP X-terminal this way until now.
That includes graphics from Mathematica 2.0 running on Sun.
I can't find any error logs on either the Sun or the HP9000 about
the problem, and re-booting the HP X-terminal blows away its
internal log files.
Some further configuration information:
Sun: 4/280S running SunOS 4.1.1 and X11R4 through patch 18.
HP9000: Model 750 running HP-UX 8.07, with the HP supplied
X libraries.
HP X-terminal: Running server code C2708A, Release B.03.01.
In addition, the file /usr/lib/X11/app-defaults/Motifps installed on
the HP9000 by Mathematica has been copied onto the Sun.
