Newer upower versions no longer emit that signal since this handled by systemd. <div class="gmail_quote">Am 16.03.2014 14:59 schrieb "Antoine Martin" <<a href="mailto:antoine@nagafix.co.uk">antoine@nagafix.co.uk</a>>: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi, My application needs to know when the machine has just resumed from suspended state. So, it seems that what is needed is just this UPower "Resuming" signal that I should be able to receive via dbus: <a href="http://upower.freedesktop.org/docs/UPower.html#UPower::Resuming" target="_blank">http://upower.freedesktop.org/docs/UPower.html#UPower::Resuming</a> It does seem to work on some distributions (it is quite a bit harder to test with VirtualBox since it does its own suspend-resume..) Unfortunately, on Fedora 20 nothing happens, no signal is emitted (that I can see), neither automatically nor by firing this script by hand: /usr/lib/systemd/system/upower.service I have already reported this bug in RedHat's bugzilla for Fedora 20: <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1064906" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1064906</a> But since there is no activity here, I thought I might ask here instead. Any ideas?
