Re: [LAU] running jackd from rc.local

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.
