HI Guys,

Thank you for all the info. So I now have several options.

1) recompiling with dbus disabled.
2) use jack1

I think either will work for me, but i’d just like to know. My other system has S11 installed, but when i’m booting into console mode, jack also works fine.
So, does this mean the mere presence of X11 on a system (without actually running it) is enough? 

cheers,
Fokke

Hi Fokke,

If you just want Jack and don't have a need for dbus either disable dbus support in Jack2, see https://github.com/jackaudio/jack2/blob/a96111a7a3bed8a0bacd1af64748c652defb5a5e/wscript#L403 or use jack1.

Hi Guys,

I’m trying to set up a minimal audio system (without X11) based on the ubuntu mini-iso.

When trying to start jack, i get this dbus error message:

No X11 -> No DBus

 Not true. I have done
dbus-launch screen
and used screen as my text only session manager with success. jack_control was able to start jackdbus, pulse was able to run and bridge to jack on a headless system. (it has been a while, I stopped because the system I was using was too memory strapped) Any of the terminals in the same screen instance will be able to communicate with any other.

So it is possible. It does mean learning more about your system... at a system level. There is also a startjack script out there that sort of hacks around this problem, but it does not leave dbus usable for anything else. (I can't find it right now)
