@karsten13 Hello,
I’ve given up. I’ve tried the following.
I created a new image, currently only available for the Rock-F2.
A Debian Bullseye Desktop LXDM display manager (Debian Xfce) without an X server.
I’m currently using an RPi 3 again, and I’ve managed to get everything working.

Thanks very much for your support.
Olaf

Hello,

I have a problem with my Mirror Docker.
My hardware is not a Raspberry PI but a radxa ROCK 2F with a 128 GB SC card.
I have Docker and Portainer installed, and of course also the Mirror Docker software.
When I start the Docker container, I get a black screen and unfortunately, no content from the Mirror software is displayed.

I get the following error when starting the labwc container:

The MM container keeps restarting because it doesn’t have a display:

What do I have to do to get the labwc container to start or initialize the display?

Thank you very much for any information.

Best regards,

Olaf
