systemd-hybrid-sleep.service(8)



NAME

   systemd-suspend.service, systemd-hibernate.service, systemd-hybrid-
   sleep.service, systemd-sleep - System sleep state logic

SYNOPSIS

   systemd-suspend.service

   systemd-hibernate.service

   systemd-hybrid-sleep.service

   /lib/systemd/system-sleep

DESCRIPTION

   systemd-suspend.service is a system service that is pulled in by
   suspend.target and is responsible for the actual system suspend.
   Similarly, systemd-hibernate.service is pulled in by hibernate.target
   to execute the actual hibernation. Finally,
   systemd-hybrid-sleep.service is pulled in by hybrid-sleep.target to
   execute hybrid hibernation with system suspend.

   Immediately before entering system suspend and/or hibernation
   systemd-suspend.service (and the other mentioned units, respectively)
   will run all executables in /lib/systemd/system-sleep/ and pass two
   arguments to them. The first argument will be "pre", the second either
   "suspend", "hibernate", or "hybrid-sleep" depending on the chosen
   action. Immediately after leaving system suspend and/or hibernation the
   same executables are run, but the first argument is now "post". All
   executables in this directory are executed in parallel, and execution
   of the action is not continued until all executables have finished.

   Note that scripts or binaries dropped in /lib/systemd/system-sleep/ are
   intended for local use only and should be considered hacks. If
   applications want to be notified of system suspend/hibernation and
   resume, there are much nicer interfaces available.

   Note that systemd-suspend.service, systemd-hibernate.service, and
   systemd-hybrid-sleep.service should never be executed directly.
   Instead, trigger system sleep states with a command such as "systemctl
   suspend" or similar.

   Internally, this service will echo a string like "mem" into
   /sys/power/state, to trigger the actual system suspend. What exactly is
   written where can be configured in the "[Sleep]" section of
   /etc/systemd/sleep.conf or a sleep.conf.d file. See systemd-
   sleep.conf(5).
