NAME¶
systemd-sleep.conf - Suspend and hibernation configuration fileSYNOPSIS¶
/etc/systemd/sleep.confDESCRIPTION¶
systemd supports three general power-saving modes: suspenda 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
