Greetings. As the subject says, I've encountered a problem using Mathematica on a system running Scientific Linux 4.4. I can't tell if the problem relates to X-windows (xorg vs. XFRee86), or to changes in Mathematica, or ... Hence, this may be wildly off-topic, and, if so, I apologize. The issue has to do with executing Mathematica on a remote system and getting the display on a local system via X-windows. Mathematica uses its own fonts for its GUI. If those fonts are missing, the front-end (GUI) is, for practical purposes, not usable. We have Mathematica available on a bunch of SL 4.x boxes in our classroom. I'd like to be able to connect via ssh to one of the classroom systems from my office, run Mathematica on the classroom system, and display the results on a SL 4.4 system in my office. We're currently using SL 4.4 on our classroom systems and the system in my office. The version of Mathematica is 5.2. In the not-too-distant past I've been able to do this combination of remote execution/local display by using the cheap, but, if I understand correctly, entirely legal trick of installing the Mathematica fonts, and no other part of Mathematica, on my local computer in exactly the same location in which the fonts are located on the remote system. I.e., if I do: local# mkdir -p /usr/local/Wolfram/Mathematica/5.2/SystemFiles/Fonts then put all the Mathematica fonts in that local directory, then I have been able to do: local$ ssh -X remote remote$ Mathematica & and have the full Mathematica front-end appear on local. Note that this worked without my having to modify any X-windows configuration at all! No "mkfontdir", no "xset fp+", etc., etc. Now what happens is that I get the input window, but I don't get the associated "palette", which contains all the integral signs, square-root signs, etc. At some level Mathematica DOES seem to be finding the fonts, because if I take a quasi-command-line approach and start typing things into the input window, the function names are in bold, the brackets and parentheses are automatically highlighted and matched, and if I type something like: Integrate[Sin[x^2], x] I get legibly-formatted output with Pi's and square-root signs looking more or less the way they look in math books. If you know where the palette went, or if you have any other words of wisdom about this, please let me know. Thanks. - Mike -- Michael Hannon mailto:[log in to unmask] Dept. of Physics 530.752.4966 University of California 530.752.4717 FAX Davis, CA 95616-8677
