[ubuntu-studio-users] weird behaviour firewire

[bart deruyter]

Hi all,

as an idea to get jackdbus stopping and then startup again I used as
Edward Schrober suggested :

sudo kill -9 4327 (the number is the pid of jackdbus)

but to no avail, jack won't start again. Now I'm on xfce, default for
ubuntustudio. So it is not gnome related, but a more general configuration
issue I think.

grtz,

Bart
