Problem to start X-Applications

Problem to start X-Applications

   Hello,
   I have problems to start X-applications on a linux machine.
   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.

   Ex: PC1-- ----->PC2-- ---->PC2
            ssh         su -

   with regards,
     Kumar
