This package provides power management support for Linux users. Gnome-power-manager is the backend program of the GNOME power management infrastructure providing a complete and integrated solution to power management under the GNOME desktop environment.
From GNOME Project: GNOME Power Manager is a session daemon for the GNOME desktop environment that makes it easy to manage your laptop or desktop system. Power management is an essential job on portable computers, and becoming more important on today's high-powered desktops. It uses many complex parts of the system - each of which is slightly different, and may contain quirks to work around. The power management policy could be influenced and tweaked by a huge number of options, and each new laptop model brings more possibilities and options. This should all work in the background without even being noticed by the user. GNOME Power Manager is written in C, and has additional dependencies of UPower 0.9.1, DBus 0.61, and libnotify 0.4.2.

UPower (previously DeviceKit-power) is a piece of middleware (an abstraction layer) for power management on Linux systems.[1] It enumerates power sources, provides statistics and history data on them and notifies users of status changes. It consists of a daemon (upowerd), an application programming interface and a set of command line tools. The daemon provides applications with its functionality over the system bus (an instance of D-Bus, service
org.freedesktop.UPower
).[2]PolicyKitrestricts access to the UPower functionality for inducing hibernate mode or shutting down the operating system (freedesktop.upower.policy).[3]Using the command-line client program upower
, one can query and monitor information on the power devices in the system. Graphical user interfaces to the functionality of UPower are e.g. the GNOME Power Manager and the Xfce Power Manager.[4]UPower is a product of the cross-desktop freedesktop.org project. As free software it is published with its source code under the terms of version 2 or later of the GNU General Public License (GPL).
It was conceived as a replacement for the corresponding parts of functionality of the deprecated HAL. 2008 David Zeuthen began a comprehensive rewrite of HAL. This produced a set of separate services under the new name 'DeviceKit'.[5] 2010 was contained therein DeviceKit-power was renamed. UPower was initially introduced and established as a standard in GNOME.[6] In January 2011 the desktop environment Xfce followed (version 4.8).
