Enumerate all power objects on the system.
||An array of object paths for devices.|
Get the object to the "display device", a composite device that represents the
status icon to show in desktop environments. You can also access the object directly
as its path is guaranteed to be /org/freedesktop/UPower/devices/DisplayDevice.
The following standard org.freedesktop.UPower.Device
properties will be defined (only
IsPresent takes a special meaning):
||An object path for the "display device.|
