I have not yet redone the help dialogs. I have removed someout of date
things and that is about it.

Two different things completely. The RT setting in -controls only shows up
if jackd2 has not been properly installed. So it would not show up on a
UbuntuStudio install (unless it is broken). it is there for people who
install jackd2 or the Studio metas into another flavour and it ends up not
installed correctly. clicking on the button corrects the install so that
audio applications have RT access. The button in qjackctl only tells jackd
if it should try to use RT mode when it runs. You should not have to use
qjackctl to start jack if you use -controls. However qjackctl when started
will show jack as already running and will allow connecting jack clients

If you need to log out and back in, -controls should have a red message

unless you changed some -controls settings it is possible jack was
running... not sure how VMs deal with reboots. The default is to use jack
as the audio server with pulse as a frontend. On my system (and my wife's)
this is invisible to the user. ie. it just works. It does not seem to use
extra CPU, pulse uses a bit less in some cases.

documentation, aside from being one of my weak points, has not been
started. (packaging is also a weak point for me, but I should learn at
least enough to package my own SW) So yes:

I don't know.
