description
This manual
page documents briefly the
pm-is-supported command.
The intended
purpose of pm-is-supported is to find out
which power management modes are supported by the system.
hald(8) will call it to do just that. (Note that UPower does
not use this.)
options
--suspend
Test whether suspend is
supported. Suspend is a state where most devices are
shutdown, except for RAM. This state still draws power.
--hibernate
Test whether hibernate is
supported. During hibernate the state of the system is saved
to disk, the system is fully powered off.
--suspend-hybrid
Test whether
hybrid-suspend is supported. Hybrid-suspend is
the process where first the state of the system is saved to
disk -- just like with hibernate --
but instead of poweroff, the system goes in suspend state,
which means it can wakeup quicker than for normal
hibernation. The advantage over suspend is that you can
resume even if you run out of power. s2both is a
hybrid-suspend implementation.
