Exactly. It should be first instance which asked for bluetooth audio.

Pulseaudio supports system-wide mode, when run system instance is running and any application running under any user can control anything in pulseaudio. So the best way would be to teach your gdm3 to stop doing such thing which is just breaking audio support and other stuff related. I think that more people should start thinking more about "no regression" instead of "break everything which is currently working". -- Pali Rohár pali.rohar@xxxxxxxxx
