Since the user session runs unprivileged, and pm-suspend/pm-hibernate need to run as root, you will need to go through a system service like upower. I know nothing about LXDE, but e.g. in GNOME, the power manager simply sends the above dbus requests when you hit the suspend button or close the lid. I would expect LXDE provides a similar user power management agent. -- Why is it that all of the instruments seeking intelligent life in the universe are pointed away from Earth?
