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

karsten13

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.

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)?

@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…
