You can use the xhost command to let root use your X server. xhost +root will add root to the list of authorized users. If you're on a home computer where you're the only one who uses it, or you don't mind if everyone can use it, you can run xhost + to disable all restrictions on who can use your X server.

Another option is to install sux and use that to switch to root. It will take care of granting access to the X server.
