When rebuilding doorbot2 I tried to get the screen stuff working again. It might (although the ansible scripts don't reflect the changes I'd been trying, as I didn't get it working) start the browser, etc. but I can't work out how to get it to automatically log in on boot.
I've tried a few things to get that working, but none made any difference.
The autostart I've tried configuring is in /etc/xdg/lxsession/rpd-x/autostart
