Local desktop development env for mir-kiosk

snapcraft
1

Hi,

I am trying to run my mir-kiosk snap in ubuntu desktop.

ubuntu-frame is running

I have added the wayland socket link to /run/user/0/wayland-0

It seems like the snap cannot connect to the wayland socket.

electron-kiosk-uc20. does work on the physical ubuntu core 20 device.

I cannot access the snap shell either.

sudo snap run --shell electron-kiosk-uc20.electron-kiosk-uc20

Is stuck at this loop

It is not obvious why you would do this. It won’t work.

Maybe this helps?

Thank you for your help.

Your screenshare works for wpe-webkit-mir-kiosk

So far I cannot get https://github.com/ogra1/electron-kiosk-uc20 to work.

I will do a fresh build and try again.

If you read the log you posted, you’ll see something that needs fixing. :wink:
