pm-is-supported(1)
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.
OPTIONS
- --suspend
- Is suspend supported? Suspend is a state where most devices are
shutdown, except for RAM. This state still draws power. - --hibernate
- Is hibernate supported? During hibernate the state of the system is saved to disk, the system is fully powered off.
- --suspend-hybrid
- Is hybrid-suspend 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.
