PROGRAM:

NAME

pm-is-supported - Test whether suspend or hibernate is supported.

SYNOPSIS

pm-is-supported [{--suspend | --hibernate | --suspend-hybrid}]

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.

RETURN VALUE

The result of the test for a certain powermanagement state is defined by the following
exit codes.

Code Diagnostic
0 State available.
1 State NOT available.
