Cannot reproduce (here with jack2 -- 1.9.11 from debian/stretch, jackdbus).

Can you start Ardour from the commandline: Is there any relevant output?

Is this an Ardour binary from (weak-linked libjack) or Ubuntu's version?

Possibly another recurring Ubuntu bug: Does temporary `jackd -T terminate?

I recently came across this issue in ubuntu. Can you verify your user is in the audio group?

Relevant ubuntu documentation: [^]

That rings a bell.. Ardour + JACK require realtime permissions (and jackd needs to run with rt-priority > 5). Ardour/ALSA will only print a warning but not hard fail if rt is not available.

The generic way is to set this up is [^]
on debian based distros you can
  `sudo dpkg-reconfigure jackd2`
allow realtime and re-login.

sudo adduser <user> audio
then logout/in is what worked for me.
