I'm trying to get Jack up and running on my Slackware64 14.1 as shown here
on alien.slackbook. But when i run qjackctl, as that page suggests, it shows in the messages that: Cannot lock down 82274202 byte memory area (Cannot allocate memory). I tried to set ulimit -l but can't as non-root user. I tried to set the limit in /sbin/initscript but that didn't work either. Some other Linux distributions use /etc/security/limits.conf but that doesn't seem to work with slackware (or am i wrong?). On a forum a similar (ulimit) problem with slackware describes the use of set_rlimit, a command i do not seem to have (maybe older slackware version?).
The current ulimit -l setting is 64kB, which seems very low. As root i have no problem setting this to 90000. But how do i do this as non-root? Running ulimit -H -l shows 64kB is also the hard limit (even though root can go above it). I am curious to know how do i change the hard limit system-wide? Would that fix my problem?
Thanks for any pointers.
Same thing for real-time scheduling btw...
