I installed Fedora Core 7 and Cell SDK v3.0. When I run the system simulator I want to be able to open an xterm window on the host system by issuing the xterm command on the simulated Linux system. Here's what I've done so far: - ssh'ed into the simulated system from the host system to check if bogus net is set up properly - typed 'export DISPLAY=172.20.0.1:0' in the console of the simulated system to get it to send graphical output to the host system - executed gdmsetup on the host system and made sure that 'Deny TCP connections to Xserver' isn't checked - after that I type 'gdm-restart' to restart the window manager So after the the window manager has restarted and I've logged in again, I restart the Cell simulator and type 'xterm'. Here's what I get: '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' Apparently the warning isn't all that important, but how do I get rid of 'xterm Xt error: Can't open display: %s'?
