Change the sshd_config to allow direct root logins.

Then do ssh -X root@debian.box.

If you're the paranoid type, or if the Debian system is exposed to the
public Internet, then make sure you only permit root logins when using
pubkey authentication, not password.  Then set up an RSA pubkey for your
direct root login.
