Thanks! I will check for that signal, then (especially as I don't have a QMaemo5HomescreenAdaptor around when Fettuccine is running as an app ).

BTW, another newbie question here: I've just been browsing the documentation a bit, and along with the screen lock signal, there appears to be a screen "status" signal (with values for "on", "dimmed", and "off"):

Would you know if "on" and "off" for this signal are identical to "locked" and "unlocked" for the tklock mode signal, or can the screen go dark without being in "locked" mode? (I seem to recall situations where the screen was dark but still detected when I touched it...)
