      the 4 objects are o.k., one network and 3 containers (init is only for setting correct permissions in the mount folders, it runs for a very short time, you can disable it in the .env file if wanted).

      Question: When the failed to connect to display occurs, how do you get the screen back working? Is a docker rm -f labwc && docker compose up -d sufficient or a docker compose up -d --force-recreate? Or do you have do reboot? Or do you switch the monitor off and on?

      Other idea is to implement a wlr-randr call every 30min. in the labwc container.

        @karsten13 i have disabled the init container as suggested.

        When the display fails I can get it back with docker rm -f labwc && docker compose up -d (docker compose up -d --force-recreate also works but docker compose up -d on it’s own doesn’t). I am running it today with the MMM-Universal-Pir module disabled as another test (although when sitting at a login prompt it never went off).

        Note that the display fails after a few hours of no PIR trigger, it doesn’t have to be overnight.

          so restarting only the labwc container solves the problem …

          I will try to build a labwc container which executes wlr-randr e.g. every 30min. so we can see if this helps.

            you can now test with a new labwc container which does the wlr-randr call every 15min. but I’m not sure this helps …

            For testing change this line in the .env file

            LABWC_IMAGE="karsten13/labwc:develop"
            

            and then do a docker compose pull && docker compose up -d

              @karsten13 unfortunately that change did not prevent the display from dropping. There’s no time timestamp in the docker logs for labwc but when i looked this morning there were some 40 calls to wlr-randr that had failed. If they are every 15mins that’s about 10:00 it failed. I will make a more accurate observation tonight

                I expected this already …

                can you post the exact error message of wlr-randr when it fails?

                Other point: What happens if you disable MMM-Universal-Pir for a test? Are you still getting the errors or does mm runs correctly over night?

                  for testing I added wlopm to the current mm-develop docker image.

                  So for another test use this lines in the .env file

                  MM_IMAGE="karsten13/magicmirror:develop"
                  LABWC_IMAGE="karsten13/labwc:develop"
                  

                  Then change the on/off commands in the config.js

                                          module: "MMM-Universal-Pir",
                                          position: "top_right",
                                          config: {
                                                  onCommand: "wlopm --on HDMI-A-1",
                                                  offCommand: "wlopm --off HDMI-A-1",
                                          }
                  

                  and then do a docker compose pull && docker compose up -d

                    @karsten13 I left it running overnight with the MMM-Universal-Pir config lines commented out and the monitor physically switched off and this morning MM was still working fine when I switched the monitor back on again. When I looked at docker logs labwc the wlr-randr command was failing (still being triggered every fifteen mins) which suggests the connection between the MMM-Universal-Pir and the display driver is the issue rather than the display actually going off. I will try your new build today although i will have to add --transform 90 to the onCommand to get my screen rotation.

                      @karsten13 my apologies, I see the transform is not needed as you have taken the rotation into account
