Yes, by default XDM/WDM/etc uses magic cookies. Even root doesn't have
authority to override this. My solution is that when I log in as a
user and then su to root and then need to display some X stuff as root
is to run, as root:
export XAUTHORITY=~username/.Xauthority;export DISPLAY=:0
Just replace "username" with the login ID you used when you logged in
and started up X.
