sudo strips nearly all environment variables from programs you run via it. The list of stripped variables includes $DISPLAY and $XAUTHORITY, and both of those are necessary to run any X client. The default sudo configuration is perfectly ok, and there's no need to change it. The reason being - it *very* simple to lower overall system security by changing nearly anything in /etc/sudoers. Yet there's a way to solve your problem - get a habit of running X clients like this: HOME=/root sudo -E xterm Re-defining $HOME is crucial as otherwise you risk users' rewriting configuration files by root.
