Hi all,
I updated to ubuntu 10.04 it asked me if I wanted a real-time kernel. I
agreed. when I start jack I get a warning:
Memory locking is unlimited - this is dangerous. You should probably alter
the line:
@audio - memlock unlimited
in your /etc/limits.conf to read:
@audio - memlock 769515
I went to the limits.conf there was only:
@audio - rtpro-99 (or something similar). not
@audio - memlock unlimited

"Beginning with the Ubuntu package
jack-audio-connection-kit-0.118+svn3796-1ubuntu2 editing of
/etc/security/limits.conf should not be required."
BUT:
ubuntustudio-audio metapackage has not yet deprecated this script that
writes:
@audio - rtprio 99
in
/etc/security/limits.conf
Under system administrator ubuntu studio controls
there is a setting for
memlock can I set it there?
Ubuntustudio-controls will write to /etc/security/limits.conf
Leave it alone and use the command line.

I think jack suggests 75% of your RAM memory. At least in my case, it was
exactly so. I suppose this is safer than "unlimited".
