Jack 2 works fine with Alsa and without pulse.  That's how I've been
using it for years.  The jack2 man page says "Alsa MIDI", as I posted
earlier.

To stop pulseaudio, kill the daemon if it's running and comment out
the lines in /etc/asound.conf:

#pcm.default pulse
#ctl.default pulse

Then chmod -x /etc/rc.d/rc.pulseaudio to make sure it doesn't start
at boot.

This is the non-purist way of not using pulseaudio, and has worked
for me since the release of 14.2.

Also, the man page mentions about dbus:

Defining $JACK_NO_AUDIO_RESERVATION will bypass audio device
reservation via session bus (DBus).  This can be useful if JACK was
compiled with DBus support but should run on a headless system.

I can confirm that it stops all the errors about X11 not running.
