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.<div><div class="h5"><br>

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