    @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?

              yes, I tested this by killing and restarting the labwc-container from outside.

              Not nice but I have no idea how to solve this.

                @karsten13 I thought that would be the case. I tried changing the initial RANDR_PARAMS="--output HDMI-A-1 --transform 90" in the .env file to RANDR_PARAMS="--output HDMI-A-1 --off" so that the MMM-Universal-Pir module would be responsible for the first switch on of the display but then I got no display on restart at all.

                  @smegbadger

                  had to write it down:

                  labwc	after start			wlr-randr --output HDMI-A-1 --transform 90
                  mm	starts and mm is displayed
                  mm	offCommand			wlr-randr --output HDMI-A-1 --off
                  mm	still up but not displayed
                  labwc	fails after a while, killed
                  labwc	after start			wlr-randr --output HDMI-A-1 --transform 90
                  mm	still up and displayed again
                  mm	offCommand			wlr-randr --output HDMI-A-1 --off
                  ...
                  

                  so another idea would be to execute the command defined in RANDR_PARAMS only if the display is not switched off. Will check if I can get this information …

                    I think I have now a working solution for this.

                    For testing

                    use LABWC_IMAGE="karsten13/labwc:develop" in .env.

                    In /opt/mm do

                    # check if worktree is clean
                    git status
                    # switch to develop branch
                    git switch develop
                    # pull
                    git pull
                    

                    Go to /opt/mm/run and execute docker compose pull and docker compose up -d --force-recreate.

                    With these changes the screen should still be blank after a restart of the labwc-container if the screen was blank before. Let me know if it works.

                      @karsten13 unfortunately that didn’t work.
                      In the morning the screen was off and could not be restored with docker rm -f labwc && docker compose up -d or docker compose up -d --force-recreate. In both cases the console briefly came back and then the the monitor slept again. Only when i when into the labwc container and did wlr-randr --output HDMI-A-1 --on --transform 90 did the display return. At that point the MMM-Universal-Pir started counting down too and it works as normal.
