Yep, sshd sets up the DISPLAY variable when you log in. It
should be of the form remotehost.domain:x.0, where x is number,
probably 10 or above. This causes all X communication to go
through the encrypted channel. So changing DISPLAY to where the
X server is will defeat the purpose of running via ssh :)
Anyway, you need to get rid of the "bad display name" error. I'm
not sure exactly how. Perhaps "dinkey" doesn't resolve from the
remote machine? Are there any weird things in your login scripts
which could be interfering with sshd's tunneling? Again, running
with "ssh -v" might help.

Hope you work it out. Remember to post how you fixed it if you
find out, for future generations :)
