.SH DESCRIPTION
The \fIxscreensaver\-command\fP program controls a running \fIxscreensaver\fP
process by sending it client-messages.
will notice, and deactivate.)
.TP 8
.B \-deactivate
-If the screensaver is active (the screen is blanked), this command will
-deactivate it just as if there had been keyboard or mouse activity.
-If locking is enabled, then the screensaver will prompt for a password
-as usual.
+This tells xscreensaver to pretend that there has just been user activity.
+This means that if the screensaver is active (the screen is blanked),
+then this command will cause the screen to un-blank as if there had been
+keyboard or mouse activity. If the screen is locked, then the password
+dialog will pop up first, as usual. If the screen is not blanked, then
+this simulated user activity will re-start the countdown (so, issuing
+the \fI\-deactivate\fP command periodically is \fIone\fP way to prevent
+the screen from blanking.)
.TP 8
.B \-cycle
If the screensaver is active (the screen is blanked), then stop the current
.BR xscreensaver (1)
for details.
.TP 8
-.B \-throttle
-Temporarily switch to ``blank screen'' mode, and don't run any display modes
-at all, until the screensaver is next de-activated. This is useful if you're
-using a machine remotely, and you find that some display modes are using too
-much CPU.
-
-(If you want to do this \fIpermanently\fP, that is, you want the screen saver
-to only blank the screen and not run demos at all, then set the \fIprograms\fP
-resource to an empty list: See
-.BR xscreensaver (1)
-for details.)
-.TP 8
-.B \-unthrottle
-Turn `-throttle' mode off and resume normal behavior.
-.TP 8
.B \-version
Prints the version of xscreensaver that is currently running on the display:
that is, the actual version number of the running xscreensaver background
Note that LOCK might come either with or without a preceeding BLANK
(depending on whether the lock-timeout is non-zero), so the above program
keeps track of both of them.
+.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.
.SH DIAGNOSTICS
If an error occurs while communicating with the \fIxscreensaver\fP daemon, or
if the daemon reports an error, a diagnostic message will be printed to
and related tools can always be found at http://www.jwz.org/xscreensaver/
