-restart
Restarts the server with the same options used when it was initially invoked.
This reloads the configuration file and is useful when you have changed the ~/
.xscreensaver file manually (or copied one from another account).
-activate
-deactivate
Immediately enables or disables the screen saver, respectively.
-watch
Prints screensaver events to the screen as they happen; useful for logging and to
trigger other events that should take place when the screensaver is activated
(such as causing a kiosk to revert to its initial state; see Section 15.8).
For example, this command will cause xscreensaver to start immediately, as though
the display had been left idle for a long period of time:
$ xscreensaver-command -activate
Note that xscreensaver will set the server??™s DPMS timeouts to the values contained in
~/.xscreensaver when started. This will override the DPMS settings in the X server
configuration file (Section 3.11) or previously set with xset (Section 6.12).

To help secure the display when it??™s idle, you can configure xscreensaver to lock the
display; the login password is required to unlock it. But beware: this provides little
protection if the X server was started from a character-mode VT (Section 2.
