power-profiles-daemon provides a common interface for selecting system power behaviour on Linux. It exposes its functionality over D-Bus so desktop environments and applications can offer power controls without needing to understand the hardware-specific mechanisms underneath.
The daemon centres on power-saver, balanced and performance profiles. Performance availability depends on the hardware and drivers, while the other profiles provide broadly available policies.
Hardware-specific drivers and actions translate the selected policy into suitable platform settings. Applications can also request temporary profile holds when they have a specific performance or power-saving requirement.
This is free and open source software.
Key Features
- Expose power-saver, balanced and performance profiles through a standard D-Bus interface.
- Integrate with power-management controls provided by KDE Plasma and GNOME.
- Provide powerprofilesctl for querying and changing profiles from the command line.
- List the profiles supported by the current hardware.
- Launch a command while temporarily holding the performance or power-saver profile.
- Report applications that currently hold a particular power profile and the reason for each hold.
- Support multiple hardware drivers and profile actions on the same system.
- List configurable power-saving actions and enable or disable individual actions.
- Support behaviour that reacts to battery level and AC adapter changes.
- Persist relevant configuration so selected behaviour can be restored.
- Support hardware-specific actions such as panel power saving on compatible AMD graphics hardware.
- Support optional AMDGPU dynamic power-management behaviour.
- Report when the performance profile is degraded and expose the reason to frontends.
- Provide an API applications can use to react when the user requests lower-power operation.
