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-0.0.25 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.

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).
