NAME
systemd-sleep.conf - Suspend and hibernation configuration file
SYNOPSIS
/etc/systemd/sleep.conf
DESCRIPTION
systemd supports three general power-saving modes:
suspend
a low-power state where execution of the OS is paused, and complete
power loss might result in lost data, and which is fast to enter
and exit. This corresponds to suspend, standby, or freeze states as
understood by the kernel.
hibernate
a low-power state where execution of the OS is paused, and complete
power loss does not result in lost data, and which might be slow to
enter and exit. This corresponds to the hibernation as understood
by the kernel.
hybrid-sleep
a low-power state where execution of the OS is paused, which might
be slow to enter, and on complete power loss does not result in
lost data but might be slower to exit in that case. This mode is
called suspend-to-both by the kernel.
Settings in this file determine what strings will be written to
/sys/power/disk and /sys/power/state by systemd-sleep(8) when
systemd(1) attempts to suspend or hibernate the machine.
OPTIONS
The following options can be configured in the "[Sleep]" section of
/etc/systemd/sleep.conf:
SuspendMode=, HibernateMode=, HybridSleepMode=
The string to be written to /sys/power/disk by, respectively,
systemd-suspend.service(8), systemd-hibernate.service(8), or
systemd-hybrid-sleep.service(8). More than one value can be
specified by separating multiple values with whitespace. They will
be tried in turn, until one is written without error. If neither
succeeds, the operation will be aborted.
SuspendState=, HibernateState=, HybridSleepState=
The string to be written to /sys/power/state by, respectively,
systemd-suspend.service(8), systemd-hibernate.service(8), or
systemd-hybrid-sleep.service(8). More than one value can be
specified by separating multiple values with whitespace. They will
be tried in turn, until one is written without error. If neither
succeeds, the operation will be aborted.
EXAMPLE: FREEZE
Example: to exploit the "freeze" mode added in Linux 3.9, one can use
systemctl suspend with
[Sleep]
SuspendState=freeze
