NAME

       xscreensaver-systemd  -  lock  the screen upon suspend, and inhibit screen-blanking during
       video playback.

SYNOPSIS

       xscreensaver-systemd [-verbose]

DESCRIPTION

       The xscreensaver-systemd program is a  helper  program  launched  by  xscreensaver(1)  for
       systemd(1) or elogind(8) integration.  It does two things:

       * When  the  system is about to go to sleep (e.g., the laptop lid has just been closed) it
         locks the  screen  just  before  the  system  sleeps,  by  running  xscreensaver-command
         -suspend.   When  the system wakes up again, it runs xscreensaver-command -deactivate to
         make   the   unlock   dialog   appear   immediately.    It   does   this   through   the
         org.freedesktop.login1(5) D-Bus interface.

       * When  another  process  on  the  system  asks for the screen saver to be inhibited (e.g.
         because  a  video  is  playing)  this  program  periodically  runs  xscreensaver-command
         -deactivate  to  keep the display un-blanked.  It does this until the other program asks
         for it to stop, or exits.  It does this through the org.freedesktop.ScreenSaver(5) D-Bus
         interface.

BUGS

       Only  one  program at a time can register with systemd(1) for screen-saver-related events,
       so if another screen saver is running as a part of the desktop environment,  xscreensaver-
       systemd   will   be  unable  to  launch.   Likely  adversaries  include  ksmserver(1)  and
       gsd-screensaver-proxy(1).
