If you tell the list what exactly you did, it will propably be much easier for 
the people reading this list to help you.
How did you connect to the remote machine? For example
ssh -X <host>
or
ssh -Y <host>?
If you neither use "-X" nor "-Y" is "ForwardX11" set to "yes" in the local 
ssh_config?
Is the DISPLAY environment variable appropriately set on the remote machine?
Does the sshd_config on the remote machine allow X11Forwarding?
Is the error message above really complete? No hint which X server the remote 
app fails to connect to?
