Hey Peter, Richard is on vacation currently. As for your question, the basic problem is that the kernel doesn't have any way to signal suspend/resume to observers. Until that is fixed, userspace signals such as the upower ones (or the pm-utils ones, or the systemd ones,...) can only be hacks that don't work 100% reliably :-( _______________________________________________ devkit-devel mailing list devkit-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/devkit-devel
