I’ve tried 5 different snaps on 2 different systems.
Os list
- 1.os: Ubuntu 18.04 LTS (x86)
- 2.os: An Ubuntu Core Virtual Machine hosted by 1.os.
Command to start mir-kiosk on 1.os:
sudo mir-kiosk --x11-output 800x600
Command to launch the virtual machine for 2.os:
sudo kvm -smp 2 -m 1500 -netdev user,id=mynet0,hostfwd=tcp::8022-:22,hostfwd=tcp::8090-:80 -device\
virtio-net-pci,netdev=mynet0 -vga qxl -drive file=ubuntu-core-18-amd64.img,format=raw
App list
I tried all the apps in standard and in devmode:
- 1.app: wpe-webkit-mir-kiosk
- 2.app: chromium-mir-kiosk
- 3.app: mir-kiosk-apps
- 4.app: mir-kiosk-scummvm
- 5.app: electron-hello-world-kiosk
On 1.os:
-
1.app, 5.app, 2.app
it starts in about 1-10 minutes (a lot of time!). The app is very slow to start but it’s very fast after the boot. -
3.app, 4.app
it starts
On 2.os:
-
1.app, 2.app, 5.app
it doesn’t start -
3.app, 4.app
it starts
2.os - snap logs wpe-webkit-mir-kiosk -n60:

On 2.os mir-kiosk starts at boot and I can see the mouse pointer and the orange splash screen.

Is a Wayland server running?
You could try running as root
