[ubuntu-studio-users] Cannot use real-time scheduling - Operation not permitted

[Neil McBennett]

Hi All,
> I recently upgraded to version 20.04 and have hit a problem with jackd and
> real time scheduling. I get the output below in syslog
> I know there have been kernel changes relating to this and I have seen
> talk of using cgroups etc. I'm wondering if I should just go for a fresh
> install but if anyone has any suggestions I'd be very grateful to know
> before re-installing.
