Version 2.34.0 - Missing X Server or $DISPLAY (Docker version of MMOS)

Mathes75

@karsten13 New issue. I did the

cd /opt/mm
git pull
./install/install.sh electron

again and now I’m facing:

pi@magicmirrorMB:/opt/mm $ ./install/install.sh electron

--> Check docker installation

Docker is already installed:
Docker version 29.1.3, build f52814d
Docker Compose version v5.0.1
Found no xserver or wayland so using own container

--> Pulling container images and starting magicmirror

Going to remove mm

Don´t know what went wrong.

Any way to get back to the easy issue?

@Mathes75

looks like you still have an old labwc image, try from /opt/mm/run folder:

docker compose pull
docker compose up -d

Back to function! Several restarts without blank screen!

Pi rebooted twice today (initiated by myself) and issue didn’t come back - I think this can bei marked as resolved - thanks a lot!

Now I can take care about Python and fritzconnector…
