Hi,
As I heard from the Debian jackd maintainer:
In Debian testing/ squeeze and very likely in Ubuntu lucid, it's not
neccesary anymore to manual edit /etc/security/limits.conf! It's been
automatically done by jackd in /etc/security/limits.d/audio.conf and it
will conflict with /etc/security/limits.conf.

Such things are good to know if you're member of the LAU community, and
I feel communication is lacking often with these kind of things...
Thank you. I have just installed lucid daily
build. I had already added the "rtprio 99" and "memlock unlimited" lines to /etc/security/limits.conf even if, surprisingly for me, jackd does start with the -R option. I will undo it before I restart the computer.

I wonder about the nice value. It is there but commented out. jackaudio.org don't even mention it. What is it for?
Cheers! Pablo
