Why do you use ssh to connect to the local machine? I would propose to
use "su" to switch to a root account. In order to allow root the access
to the X-Server, it is sufficient to set the environment-variables 
DISPLAY=":0"
XAUTHORITY="/home/username/.Xauthority"
, "username" beeing the user who is running the X-session.
