I# /usr/X11R6/bin/xscreensaver -display $DISPLAY
xscreensaver: 01:02:41: locking is disabled (running as nobody).
xscreensaver: 01:02:41: locking only works when xscreensaver is launched
         by a normal, non-privileged user (e.g., not "root".)
         See the manual for details.

man the xscreensaver thingie isnt kidding about it...
