Description

Profile actions are actions to run on profile change that do not affect the overall power usage, or performance level of the system, but instead of individual components.

For example, an action might want to save energy when in the power-saver profile, and thus reduce the charging speed of a particular device. Or it could automatically reduce the speed of animations, or luminosity of an RGB keyboard.

The list of actions that are currently running is available through the D-Bus API.

Note that power-profiles-daemon can only accept PpdActions that will not make devices appear “broken” to users not in the know, so actions will never disable Wi-Fi or Bluetooth, or make some buttons stop working until power saving is turned off.

struct PpdActionClass {
  GObjectClass   parent_class;

  PpdProbeResult (* probe)            (PpdAction                   *action);

                                       PpdProfile                   profile,
                                       GError                     **error);
  gboolean       (* power_changed)    (PpdAction                   *action,
                                       PpdPowerChangedReason        reason,
                                       GError                     **error);
  gboolean       (* battery_changed)  (PpdAction                   *action,
                                       gdouble                      val,
                                       GError                     **error);
};

New profile actions should derive from PpdAction and implement at least activate_profile .
