Bug#805414: gdm3: disable pulseaudio to prevent capturing A2DP sink on session start

[Arnaud Rebillout]

Just an update on this bug, as it is in Debian unstable.

I noticed that the bug can't be reproduced on a GNOME/Wayland session. I
can see in the logs that the PA GDM daemon gets killed with SIGTERM. I
don't know enough about Wayland to tell you what happens there. I'm just
surprised because I *think* I bumped into this bug at a time where I was
running GNOME/Wayland, so I'm not sure if there was a change in Wayland,
or if I'm mistaken.

In any case, for those running GNOME/X11, the bug is still there and can
be reproduced.

(choosing between Wayland/X11 is done by editing the file
/etc/gdm3/daemon.conf)

There's an effort to solve that upstream at
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/merge_requests/10,
I just pushed an updated version of a patch.

Thanks,

  Arnaud
