Hey,
Can't seem to start jackd in realtime as user on ubuntu studio. It
does start as root, but that's hardly a consolation (unless I run all
audio software as root, which would be kinda daft IMO)
@audio - rtprio 99
@audio - nice -10
@audio - memlock unlimited
have been added to /etc/security/limits.conf
Nevertheless, starting it as user just doesn't seem to work, and I
just can't figure out why. I've googled the issue, and everybody seems
to agree that modifying limits.conf in the above manner should solve
the problem - yet this is what I get:
mick@kaizoku:~$ jackd -R -P89 -dalsa -dhw:0 -r48000 -p256 -n3 -S &
[1] 3092
mick@kaizoku:~$ no message buffer overruns

Any ideas?
Not sure if this is a possible answer to the question, or perhaps another
question altogether, but ... I've struggled with the same issue on a debian
system for some time, then discovered this in /etc/pam.d/su -
# Sets up user limits, please uncomment and read /etc/security/limits.conf
# to enable this functionality.
# (Replaces the use of /etc/limits in old login)
# session required pam_limits.so
So far, I'm still not sure if uncommenting the 'session required
pam_limits.so'
line actually solves the problem, but I am curious.
cheers.
(I dumbly sent this to just the op instead of 'reply all', so fwiw I'm
repeating
it to the list)
