The default solution for this problem is to add the following line to
the respective entry in your ~/.ssh/config:

     ForwardX11	yes

Alternatively, Tramp would accept the following setting:

(add-to-list 'tramp-remote-process-environment
             (format "DISPLAY=%s" (getenv "DISPLAY")))

Maybe I could also recommend reading the Tramp manual, section
"Integration with other Emacs packages" :-)

Best regards, Michael.
