I had thought that would only inhibit the screensaver instead of automatic sleep. I did a quick test and in case I inhibit through org.freedesktop.ScreenSaver interface, the battery applet does not indicate any inhibit whereas through org.freedesktop.PowerManagement.Inhibit indicates that an inhibition is valid. I wonder if I should not instead make usage of the Inhibit mechanism from logind coupled with powerdevil. I am not sure if this is desired. I would forward inhibit request to logind and checks existing inhibition before allowing powerdecil to suspend. > > I can also see some other features that could make sense to provide in > > libraries that music players could use (lyrics fetching, album art > > fetching, ...).
