[yocto] Running Sato/X11 as non-root

[Gary Thomas]

In my attempt to get pulseaudio running, I need to bring up
my X11 session with a user that is not root.  The default
(core-image-sato) always starts X11 as root.  This yields
these errors when starting (with pulseaudio installed):
   W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).
   E: [autospawn] core-util.c: Home directory /home/root not ours.
   W: [autospawn] lock-autospawn.c: Cannot access autospawn lock.
   E: [pulseaudio] main.c: Failed to acquire autospawn lock
   W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).
   E: [autospawn] core-util.c: Home directory /home/root not ours.
   W: [autospawn] lock-autospawn.c: Cannot access autospawn lock.
   E: [pulseaudio] main.c: Failed to acquire autospawn lock

So, I tried to make X run as user 'demo', which I created, by
putting 'demo' in /etc/X11/Xusername.  Now it seems to try
and run as 'demo', but falls over quite quickly:
   Fatal server error:
   [2951371.651] xf86OpenConsole: Cannot open /dev/tty0 (No such file or directory)
   [2951371.651]

   Please consult the The X.Org Foundation support
          at http://wiki.x.org for help.

   [2951371.652] Server terminated with error (1). Closing log file.

Any ideas how I get this going?

n.b. not only do I want to get this going for myself, but I think
the discussion (and maybe subsequent documentation) is useful since
this functionality is in OE-core (or is it only Poky/Yocto - hard
to tell)...
