    It's a lot safer to put in root's .bashrc:

    if test "$LOGNAME" != "root"; then
       export XAUTHORITY=/home/$LOGNAME/.Xauthority
    fi

    This will give user root access to the X session of the logged-in-user.

    What you suggested will give _every_ user access to the X session,
    including the ability to read passwords etc.

    (And, if the server accepts TCP connections, "xhost +" allows everyone
    on the internet to connect, and look while you type your passords etc).
