I want to detect whether the screensaver is active.  On Ubuntu 14.04 and Fedora 21, I tried the following command:$ dbus-send --print-reply=literal --dest=org.freedesktop.ScreenSaver /org/freedesktop/ScreenSaver org.freedesktop.ScreenSaver.LockError org.freedesktop.DBus.Error.NotSupported: This method is not implementedI'm probably misunderstanding dbus-send as d-feet shows me that the method GetActive is available.How can I detect screensaver activity, preferably in a desktop independent manner? There is a related question, which however wasn't solved.
Detect if screensaver is active
d bus;screensaver
