The same happens to me, same distro, some infos are different (namely the kernel, 4.18.0-18-generic, since 5.0.0... frozes my machine - another issue to be investigated), but I don't think these differences are relevant. I've set
DefaultLimitMEMLOCK=infinity in /etc/systemd/system.conf and also /etc/systemd/user.conf (also tried to put a file in newly created /etc/systemd/user.conf.d) /etc/security/limits.d/audio.conf has @audio - rtprio 95 @audio - memlock unlimited As root I can ulimit -l to unlimited. As normal user (in the group audio of course) I can't go with more than 65536. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1837580 Title: memlock is not set Status in systemd package in Ubuntu: New Status in systemd package in Debian: Unknown Bug description: I discovered this in relation to jack, which installs /etc/security/limits.d/audio.conf, containing: @audio - rtprio 95 @audio - memlock unlimited For a user in the audio group: $ulimit -l -r max locked memory (kbytes, -l) 65536 real-time priority (-r) 95 So jack (run as user via qjackctl) reports: ERROR: Cannot lock down 82280346 byte memory area (Cannot allocate memory) but does not report that it cannot set real-time priority, which it does if run by a user not in the audio group.
