With the above warning about xhost, (that is, not using 'xhost +' but
rather 'xhost +localhost' (I have been told it's better to use xauth, but
don't understand that). In any case, the reason you're getting errors
when you try xhost is that xhost is an X command, and if root can't run X
clients, it can't run xhost. So, the solution is either to run
'xhost +localhost' from an xterm as your regular user, or to (as root) do:
cp ~username/.Xauthority ~root
(where username is the username of your regular user)
