Introduction to Power Management Utilities
The Power Management Utilities is
a small collection of scripts to suspend and hibernate computer
that can be used to run user supplied scripts on suspend and
resume.
This package is known to build and work properly using an LFS-7.7
platform.

Installation of Power Management Utilities
Install Power Management Utilities
by running the following commands:
./configure --prefix=/usr \
--sysconfdir=/etc \
--docdir=/usr/share/doc/pm-utils-1.4.1 &&
make
This package does not come with a test suite.
Now, as the root
user:
make install
If you don't have xmlto-0.0.26 installed, copy pregenerated man
pages:
install -v -m644 man/*.1 /usr/share/man/man1 &&
install -v -m644 man/*.8 /usr/share/man/man8 &&
ln -sv pm-action.8 /usr/share/man/man8/pm-suspend.8 &&
ln -sv pm-action.8 /usr/share/man/man8/pm-hibernate.8 &&
ln -sv pm-action.8 /usr/share/man/man8/pm-suspend-hybrid.8
Configuring Power Management Utilities
Suspend or resume functionality can be easily modified by
installing files into the /etc/pm/sleep.d
directory. These files, known as
hooks, are run when the system is put into a sleep state or
resumed. Default hooks are located in /usr/lib/pm-utils/sleep.d
, and user hooks should
be put in /etc/pm/sleep.d
. See the
pm-action(8) man page for more information.
In order to use hibernation with GRUB and a swap partition, you need to add
kernel parameter resume=swap_partition
(i.e.
resume=/dev/sda1
) to the kernel line
in the /boot/grub/grub.cfg
configuration file.

Short Descriptions
on_ac_power
|
is a script that determines whether the system is running
on AC power (rather than a battery).
|
pm-hibernate
|
is a symlink to pm-action script that puts the computer
into hibernate mode (the system is fully powered off and
system state is saved to disk).
|
pm-is-supported
|
is a script that checks whether power management features
such as suspend and hibernate are supported.
|
pm-powersave
|
is a script that puts the computer into powersaving (low
power) mode.
|
pm-suspend
|
is a symlink to pm-action script that puts the computer
into suspend mode (most devices are shut down and system
state is saved in RAM).
|
pm-suspend-hybrid
|
is a symlink to pm-action script that puts the computer
into hybrid-suspend mode (the system does everything it
needs to hibernate, but suspends instead of shutting
down).
