+.SH STOPPING GRAPHICS
+If xscreensaver is running, but you want it to stop running screen hacks
+(e.g., if you are logged in remotely, and you want the console to remain
+locked but just be black, with no graphics processes running) you can
+accomplish that by simply powering down the monitor remotely. In a
+minute or so, xscreensaver will notice that the monitor is off, and
+will stop running screen hacks. You can power off the monitor like so:
+.EX
+xset dpms force off
+.EE
+See the
+.BR xset (1)
+manual for more info.
+
+You can also use
+.BR xscreensaver-demo (1)
+to make the monitor power down after a few hours, meaning that xscreensaver
+will run graphics until it has been idle for the length of time you
+specified; and after that, the monitor will power off, and screen hacks
+will stop being run.
