Hi Len,
unfortunately the .desktop file is not good for me.
it is only run after I have logged in, whereas I want my script to be
started as me, but before I log in.
Is there a way to achieve that, without resorting to autologin ?

Are you really wanting to run audio while you are logged out? It would be
much easier to add a desktop file to ~/.config/autostart/ Like
jackstart.desktop with something like:
[Desktop Entry]
Encoding=UTF-8
Version=0.9.4
Type=Application
Name=AutoJack
Comment=Jackdbus starter
Exec=jack_control start
StartupNotify=false
Terminal=false
Hidden=false
Change the Exec to point to a script if you want to add config options, or
use jackd instead of jack_control if you don't care about PA-jack bridging.
This will have jack runnning from login.
If you want to headless operation then have rc.local do it as the user
that will run this stuff.

Really, the right thing to do here is to set JACK up as a system
service, with an init script, or whatever the systemd equivalent is, if
you're running systemd.
What you're using now is not actually an init script, if you have to
call it from rc.local. Init scripts go in /etc/init.d, follow specific
conventions, and are symlinked into various targets so they run only in
the appropriate run levels.

JACK isn't designed to run as a system service. In the old days the JACK
Debian package did come with an init script but that was removed because
it simply didn't work. The best way is to start JACK once you're logged in.

I don't want to start it as a system service,
I don't even run it automatically through dbus.
I am using a repackaged, more recent version than the one found in the
ubuntu repository in order to have same versions between windows and linux
jackd2 versions.

Look. You're trying to have JACK be available and waiting for you before
you log in. That's just not what JACK was designed for.
Starting it through rc.local won't work, because the sound card isn't
available yet. That leaves two options: auto-login, and a system service
/ init script. A different way of starting something before login will
not pop into existence because you want it. You must use what is available.
If I needed this, I would write an init script. Even though it's not how
JACK was meant to be run, it's possible, and it's not a dirty hack like
adding something to rc.local. It will never be portable, though, and it
will never handle changes in hardware or configuration gracefully. I
don't need this, because I use JACK the way it was designed: I log in,
start qjackctl, start JACK, then start my applications.

New subject: [Jack-Devel] [LAU] running jackd from rc.local
Hi David,
it appears that due to the nature of ubuntu* distros, I have given up the
notion of starting my audio application from within rc.local - I had
problems with alsa_(in|out) not being able to grab the soundcards in my
system.
it was suggested that I do it from my desktop environments autostart
features, but these are executed when I log in, whereas I want audio to
start up sometime during the boot process (as my user) but before I log in.
basically the idea is
-I press "power ON" button on the pc
-wait for pc to boot
-audio works through this pc
It is an audio routing workstation (and jack client) so it should normally
get audio from the jack master, do some processing and spit audio from the
soundcard i/o.
so starting everything as root with a proper init script is not in the
direction. but it appears "application autostart" is not effective either.
