Ok, more tracing on gnome-screensaver. In the latest version of gnome-screensaver, it's using gnome-session idle signal instead of idle watcher[1]. Which means the 3rd party software should also use gnome-session idle intend of gnome-screensaver.
This should be reported to upstream. 1. http://bugzilla.gnome.org/show_bug.cgi?id=567919 regards -Rex -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
