Hello, This is probably a FAQ, but I could not find the information anywhere. How do I enable realtime scheduling and memory locking in modern Fedora? I have v 28 now, maybe will have v29 soon. On my main work laptop, I can't exactly remove the system and install Fedora JAM :) so I need to do this on stock Fedora. I understand that setuid on jackd and fluidsynth would probably make things better but is this the best solution? I also need to have this on a live-USB for another laptop, but that is a rather tricky case. A pretty humble machine (AMD A6, 4Gb RAM laptop) is to be used as a "sound box" with MIDI instruments. I don't think a heavy KDE-based distribution is the ideal live image for it. If I could respin Fedora JAM into something based on IceWM, or at least LXDE, that would be great. And finally, for future reference, I would appreciate knowing how to do the same (enable realtime scheduling and memory locking) on CentOS. I am asking this in case I doinstall Linux on that AMD A6 laptop permanently. My wife uses this laptop, so I'd want something less frequently updating than Fedora, so it will be CentOS (or, if I can't get CentOS to run on the hardware, OpenSUSE). -- Mikhail "Misha" Ramendik SENIOR TECHNICAL WRITER Red Hat Ireland <https://www.redhat.com/>mramendi@redhat.com M: +353-87-9409618 <https://red.ht/sig>
