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
