Regardless of whether I start qjackctl before or not, launching rosegarden fails with this
~ # rosegarden Cannot lock down 86611866 byte memory area (Cannot allocate memory) Cannot use real-time scheduling (RR/5)(1: Operation not permitted) JackClient::AcquireSelfRealTime error Segmentation fault (core dumped)
I have no idea what 'rosegarden' even is, so just some wild guessing - this sounds like some sort of permissions/privileges/limits issue - locking down memory, (presumably a failed mlock() ?) real-time scheduling not permitted etc.
This kind of error shows up REGULARLY in suse (mostly in Leaps) i.e. it gets fixed and then it's only a matter of time before it start again, been watching the yoyo for years.
If it is an issue with rosegarden itself, it ought to show in the changelog, but I think it is probably a configuration issue. /etc/security/limits.conf is used to set limits and privileges, e.g. how much memory can be locked down. -- Per Jessen, Zürich (11.2°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
