      @smegbadger said in I cannot disable screen blanking with MagicMirrorOS:

      I can get it back with docker rm -f labwc && docker compose up -d

      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

                      I build another new labwc image. You can revert the changes done to MM_IMAGE and the on-/offCommand in your setup.

                      The new karsten13/labwc:develop now runs labwc with pid=1 (I thought that was already the case) and additionally kills labwc if the wlr-randr command fails with failed to connect to display.

                      Now the container will restart if labwc is terminated inside the container. This does not address the root issue but should be a good workaround (hopefully).

                      So please do again a docker compose pull && docker compose up -d to get the latest changes …

                        @karsten13, thank you for this. It worked well overnight last night. One question: when the wlr-randr command fails, the labwc container is then killed and then automatically restarts - will the screen be turned on then until the next PIR activity and subsequent timeout of MMM-Universal-Pir?
