[LAU] running jackd from rc.local

[Ede Wolf]

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.
