only authorized user can connect to X server, just because you are root doesn't mean you can connect to X server on given machine (just like you cannot connect to other services - e.g. you'd still need password for database, ...)
you have few options:
1) xhost (see man xhost), don't do that though!
2) as root run: xauth merge ~userThatRunsX/.Xauthority
option 2 will give you access to X server without compromising security (while it's running, if you restart X you have to run xauth again)
