just to be sure, it was the client program that failed. Ok, starting in the beginning, are you using the viz roll to configure your display tiles (in particular /etc/X11/xorg.conf) or something else ? Could you send me a /etc/X11/xorg.conf file from one of the tiles, e.g. tile-0-0. If you use the viz roll you could also use run rocks list host xconfig tile-0-0 with the correct tile name. As a second test to rule out access problems, could you run the following ssh -x <tile name> printenv DISPLAY ssh -x <tile name> xterm the first one should print something like :0.0 the second one should open an xterm on the tile display (one of the 16). If the first one does not, either update your shell config to set the display correctly or set the display before you start things on the tile, e.g. run the second test as ssh -x <tile name> 'export DISPLAY=:0.0; xterm' at this point a xterm should have opened on the given tile, if not could you send me the error message. kind regards gerrit ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
