Hi, One way to solve this problem would be using 'xhost +localhost' to enable connections to the X server from your own machine. However, this may compromise security (probably not much of a concern for a single user machine). Trying this out I noticed that on my machine I can also use start an Xwindows program as root using sudo <progname> <parameters> (including an xterm window from which I can then start arbitrary X programs).
Another less convenient, but presumably more secure method is the following: $ xauth list $DISPLAY # mark the output $ su - # xauth add <paste the above line> # export DISPLAY=<display mentioned in the pasted line.) I found this in Linux Gazette #26. There some other methods are mentioned as well. If anybody knows more about potential security risks for any of these methods, I would be interested. Greetings, Christian van Enckevort
