Powersave project is a laptop powersaving software designed to run as a daemon.
Powersave project is an incredibly useful tool designed with laptop usage in mind, but it can also be applied to workstations and servers. It provides a unified platform for controlling power management facilities on your PC. This package supports ACPI, APM, IDE-disks, and CPU frequency scaling techniques. It takes over the functionalities of APMD, ACPID, OSPMD, and CPUFREQD (now CPUSPEED) packages, thus eliminating the need to install daemons from these packages when you run the Powersave daemon.
Even if your PC does not have all the hardware specified above, you should run this daemon to manage power-saving related tasks. The overhead is minimal, and you will benefit from a unique interface and configuration environment. You can still use this tool if you change hardware in the future, such as booting ACPI instead of APM if the kernel provides better ACPI support. The daemon automatically detects your hardware and supports available features.
Powersave provides four predefined power-save schemes, each configurable, and you can add customized schemes. The current scheme automatically switches depending on the current power source. The daemon fully supports CPU frequency scaling, either through the kernel (ondemand governor) or within userspace, providing three predefined CPU policies: Dynamic, Powersave, and Performance.
It also includes battery management, warning the admin/user when the battery reaches the critical state and automatically shutting down the system on specific events (fully configurable). Supporting suspend to disk, suspend to and ram and standby, it also helps set up modules and services, including automatic CPU throttling depending on the current cooling policy.
The Powersave package has a full-featured dbus implementation for communication with various clients like kpowersave, wmpowersave, or gkrellm-powersave, with more to come.
In this release, the developers have added a function to the library to query a string list property from HAL, introduced more generic dbus functions, and used a more standard logging format. The latest version has also fixed wttyhx for distributions not calling the X server via a symlink called "X." They have also removed old, unused code.
