xhost is a weak way to handle security under X. The modern system uses a
key file, $HOME/.Xauthority. X will only accept a connection if you give a
key stored in that file. X clients started by root try to read
~root/.Xauthority, and can't find the valid key. All you have to do is to
copy ~user/.Xauthority on ~root/. This file is 600, but as you are root,
that's not a problem.
