Xfce4-power-manager manages the power sources of the computer and connected devices (wireless mice, keyboards, media players etc.). It also allows users to control the display backlight brightness and set power-saving modes for displays and monitors. In addition, xfce4-power-manager provides a set of freedesktop-compliant DBus interfaces to inform other applications about the current power level so that they can adjust their power consumption.
