xscreensaver problem

[Gerard Seibert]

I got the following information from:

    http://www.jwz.org/xscreensaver/faq.html#root-lock

% xhost +localhost
localhost being added to access control list
% su
% Password: 
# gnorpm
...
# exit
% xhost -localhost
localhost being removed from access control list


When I attempt to run the above, I receive this error message:

    xhost: unable to open display ""

Also, there is no 'gnorpm' on this system.

This is on a FreeBSD-6.2 machine. What is causing this problem?
