+Subject: power: Ensure backlight iface signal gets emited on startup
+
+When power manager is started, "PropertiesChanged" signal on the backlight
+iface needs to be emitted to allow gnome-shell quick settings
+informing backlight status.
+
+This wasn't happening because manager doesn't have session dbus
+connection until startup is done.
