In short, I’m trying to build a snap from my electron app,
first, I’m using this tutorial :
https://tutorials.ubuntu.com/tutorial/electron-kiosk#2
it’s successfully compiled, and running and showing in mir-kiosk vt4, but when I want to input it with keyboard, it’s error, blank screen, restart again, input keyboard again, blank screen, restart again, and so on…
until finally I decide to compile my electron app to deb first and using .deb for snapcraft,
with https://github.com/ubuntu/snapcraft-desktop-helpers/blob/master/snapcraft.yaml and https://github.com/MirServer/xwayland-kiosk-helper, next combine the repo files, with basic X11-based kiosk app like in this tutorial (https://tutorials.ubuntu.com/tutorial/x11-kiosk#8),
I try make a configuration for snapcraft.yaml is like this :
name: app-kiosk-snap
version: 1

I install it with snap install --dangerous --devmode ./app-kiosk-snap.snap
but it’s return error that gtk2 not support wayland :

Anyone can help me resolve this issue? I’m using electronjs app compile it to deb, and use the deb to be installed in snap

@alan_g and @greyback
Edited:
FYI: in Ubuntu Desktop 1804, the app-kiosk and app-terminal is successfully running,
and I try using miral (Mir on X) like :
miral-app -kiosk -launcher 'Xwayland -wr :1'
DISPLAY=:1 app-kiosk
DISPLAY=:1 app-terminal
It’s successfuly running too…
