Mac Forum / Applications / Mac Applications / November 2006X11: what does "xset: unable to open display" mean?
hello all, new user here, so please be kind. :) i'm trying to run Mathematica on a remote computer from within an X11 Xterminal, but every time i try it, i get the error: xset: unable to open display xset: unable to open display xset: unable to open display i have no idea what this means. is there something i can do to get this to work? many thanks! dan > hello all, > [quoted text clipped - 12 lines] > many thanks! > dan (1) Start X11 (2) In the XTERM that starts up type ssh -Y -C <your user name on the other machine>@<the other machine> This should connect you to the other box and after you do your password log you into another xterm but this one is running on the other machine. Then type Mathmetica & (or whatevery you type to state Mathematica) and it should bring up it's windows on your box. The problem you have is DISPLAY setting is not right when you run the remote app. The ssh -Y takes care of all those details. NOTE: If you don't ssh into the other box I'm lost this is the way I've learned. --jim >> hello all, >> [quoted text clipped - 9 lines] >> i have no idea what this means. is there something i can do to get >> this to work? It means your DISPLAY environment variable is not set. >> many thanks! >> dan > (1) Start X11 This sets DISPLAY to :0.0 on your Mac, but only in xterm sessions, not in the Terminal. That's the reason for using the xterm in step (2). > (2) In the XTERM that starts up type > ssh -Y -C <your user name on the other machine>@<the other machine> > This should connect you to the other box and after you do your password > log you into another > xterm but this one is running on the other machine. But not all hosts accept "ssh -Y". If that fails, use "ssh -X" instead. Either of those should set your DISPLAY for you on the remote host. > Then type Mathmetica & (or whatevery you type to state Mathematica) and > it should bring up it's windows on your box. > The problem you have is DISPLAY setting is not right when you run the > remote app. The ssh -Y takes care of all those details.

SignatureDave Seaman U.S. Court of Appeals to review three issues concerning case of Mumia Abu-Jamal. <http://www.mumia2000.org/> thanks! ssh -Y works perfectly. well, except for the fact that all the mathematica fonts are screwed up, but i think i know how to fix that. :) dan > >> hello all, > >> [quoted text clipped - 43 lines] > concerning case of Mumia Abu-Jamal. > <http://www.mumia2000.org/> |
