Black screen on the radxa ROCK 2F, using docker

[ajoreis]

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:
2025-03-31T16:09:56.570445772Z [58:0331/180956.569442:ERROR:ozone_platform_x11.cc(245)] Missing X server or $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

@ajoreis said in Black screen on the radxa ROCK 2F, using docker:

Segmentation fault labwc

that tells you that labwc crashes, further investigation without having the used hardware is impossible.

@karsten13 this seems telling

chown: cannot access ‘/run/user/1001/gvfs’: Permission denied

@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
