This is the first release of a kiosk system for raspberry pi 4 leveraging weston, wpe webkit and cog to give you a web application container perfectly suited for kiosk displays.
https://github.com/coop/kiosk_system_rpi4
I haven’t had a chance to get into all the edge cases and there are definitely quirks I don’t quite understand with udev and requiring input devices that I need to sort out (see nerves_weston).
In the repo is a demo application where you can see how to assemble weston, cog and plug to display a “hello world” kiosk.
Feel free to reach out via slack, the forum or GitHub if you have questions or want to help out.
