Thanks for your great help, Gerrit. I tried to follow your instructions and got the following things:
[root@grrc ~]# ssh -x tile-0-0 printenv DISPLAY [root@grrc ~]# ssh -x tile-0-0 xterm Warning: This program is an suid-root program or is being run by the root user. The full text of the error or warning message cannot be safely formatted in this environment. You may get a more descriptive message by running the program as a non-root user or by removing the suid bit on the executable. xterm Xt error: Can't open display: %s xterm: DISPLAY is not set Since I'm not very familiar with xterm and X11, I have to guess that it may come from the xorg configuration files. I uploaded two configuration files as reference. Could you help me know how I can set up display in xterm or in these files?
