On Debian Sid, something seems to have installed systemd-logind (or something else?) and now when I start JACKD, it reports "Cannot use real-time scheduling (RR/10)(1: Operation not permitted)". I am a member of the audio group. ISTRC folk on the list mentioning what to do to get RT permission back? -- David W.
