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

sdetweil

@karsten13 thanks

karsten13

other questions (not clear from description):

Are you using mmos or are you using Raspberry Pi OS or another OS?

If not mmos, how did you the install? With the install script inside the repo?

Can you provide output of docker compose config?

Mathes75

Thanks a lot for having a look at my issue!

As mentioned in the first post, I downloaded the most recent Docker image of MagicMirrorOS. - no desktop, lite version. Wrote the image with Balena Etcher and let the Rpi do it’s magic after booting until “factory” MagicMirror was shown. SSHed into the Rpi and ran sudo raspi-config to adjust locales and WiFi.
I installed the desired Modules, modified the config.js - and now the Mirror works only at every third or fourth boot. (Sometimes real power cycle, sometimes sudo shutdown -r now - sometimes first works, sometimes second)

Currently it’sworking, only one Module has issues. Both containers recreated and restarted, output of docker logs labwc

@Mathes75

not sure I really fixed it but you can try

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

Let me know if there are still problems after reboot or not.

Mathes75

Thanks @karsten13!

git pull needed a commit to work. Done. Installing Electron revealed no change to apply.

At least I seem to be one step further: Recreating the images as mentioned in a post above repeatedly resolved the "missing X Server"message each time and started MagicMirror…

As I am quite done with all changes and adaptions, I am fine to keep the workaround with recreating the image(s), once the mirror needs a restart.

@Mathes75

Let me know if you get another black screen without mm start after reboot (I want to know if it is fixed or not …)

Can you please show me again the output of docker compose config (so I can check if you have the latest changes)?
