I'm using Crunchbang Waldorf with the Jessie repositories, and suspend functionality has recently been broken. It seems that UPower, the tool Crunchbang used to suspend, just removed suspend functionality.
The suspend command executes like this:
jaapz at jipjip in ~ $ dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend Error org.freedesktop.DBus.Error.UnknownMethod: Method "Suspend" with signature "" on interface "org.freedesktop.UPower" doesn't exist
I cannot find why the suspend functionality has just disappeared, does anyone know a solution?
