Iam logging from my Linux pc via ssh on a remote Linux machine with my username/password. In this session I can start X-Application on remote PC(xclock for example) I have in sshd_config(remote linux machine) file following 2 parameters are defined as given below: X11Forwarding yes PermitRootLogin no When I execute su command(su -) and start xclock on the remote linux, then I get the following error: Error:Cannot open Display I also tried after executing "setenv DISPLAY pcxxxx:0" without success. I must say that when I login with "su -m" and then start xclock then it works. But then I donot have the correct path definition for root.
