hi there,
which distro are you using.
if you're using ubuntu* then the fact that it asks for X is related to you
using the jack-dbus. compile a jack version without dbus support and you'll
be fine.
also the guys are jack-devel mail list have been more than helpful.
apparently to get elevated permission while rc.local is executed you need
to uncomment in /etc/pam.d/su
session required pam_limits.so
but generally speaking, rc.local is a BAD way to do boot startups in
ubuntu* and this is because ubuntu* set device permissions based on
the *logged
in* user.
It is advised to use the autostart utilities of you desktop environment,
which is what I will do now.

Great you've asked, I am having the same problem.
"su - user" does not
work, but logging in as user and run the same command does. Happens with
both, jack and jack2. With jack2 I am also getting an error that it can't
open X, wenn run from command line. But that maybe an issue specific to the
jack2 version of arch, as there is no reason why jackd should need a
display.

Hi all,
I am trying to run jackd instance from /etc/rc.local (along with a few
other applications) from a custom made init script.
The system is ubuntustudio and I have setup everything to have elevated
permissions when executing applications from the @audio group.
so when I am logged on, I see this:
nass@starkill:~$ ulimit -r -l
real-time priority (-r) 95
max locked memory (kbytes, -l) unlimited
which is expected and I can execute the script I wrote.
but, when I execute my script from /etc/rc.local as
su - nass -c "ulimits -r -l cd audio_setup/scripts ; bash ./start_audio"
then my user does not (yet?) have elevated permissions.
real-time priority (-r) 0
max locked memory (kbytes, -l) 64
is there a script I can run before my start_audio script to elevate my
permissions?
thank you
