In the current rebuild of my BNR ( http://lsn.ponderworthy.com
    ), I noticed that I could not get qjackctl to cooperate with
    jackdbus, though traditional manual startup seems to work very
    well.  The Arch wiki said that qjackctl is becoming outmoded, and
    recommended 'cadence', part of the KXStudio toolset, instead;
    cadence cooperates with dbus better, but doesn't autostart, and I'm
    missing something in the compilation which will ungray the patchbay
    autoarrange.  Anyone have corroboration and/or new best practices? 
    I am using Manjaro, but saw the same behavior when I tested Debian
    Stable and Testing.
