I cannot disable screen blanking with MagicMirrorOS
-
@karsten13 my apologies, I see the transform is not needed as you have taken the rotation into account
-
@karsten13 the display failed today as before but we have timestamps in the

I build another new labwc image. You can revert the changes done to
MM_IMAGEand theon-/offCommandin your setup.The new
karsten13/labwc:developnow runslabwcwith pid=1 (I thought that was already the case) and additionally killslabwcif thewlr-randrcommand fails withfailed to connect to display.Now the container will restart if
labwcis 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 -dto get the latest changes … -
@karsten13, thank you for this. It worked well overnight last night. One question: when the
wlr-randrcommand fails, thelabwccontainer is then killed and then automatically restarts - will the screen be turned on then until the next PIR activity and subsequent timeout ofMMM-Universal-Pir?Steve

@smegbadger said in I cannot disable screen blanking with MagicMirrorOS:
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.envfile toRANDR_PARAMS="--output HDMI-A-1 --off"so that theMMM-Universal-Pirmodule would be responsible for the first switch on of the display but then I got no display on restart at all.Steve
-
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_PARAMSonly 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/mmdo# check if worktree is clean git status # switch to develop branch git switch develop # pull git pullGo to
/opt/mm/runand executedocker compose pullanddocker 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 withdocker rm -f labwc && docker compose up -dordocker 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 thelabwccontainer and didwlr-randr --output HDMI-A-1 --on --transform 90did the display return. At that point theMMM-Universal-Pirstarted counting down too and it works as normal.magicm@magicmirror:/opt/mm/run $ docker rm -f labwc && docker compose up -d labwc [+] Running 2/2 ✔ Container mm Running 0.0s ✔ Container labwc Started 0.5s magicm@magicmirror:/opt/mm/run $ docker compose up -d --force-recreate [+] Running 2/2 ✔ Container mm Started 1.7s ✔ Container labwc Started 1.8s magicm@magicmirror:/opt/mm/run $ >>> still no screen output <<< magicm@magicmirror:/opt/mm/run $ docker exec -it labwc bash pi@3f4fb5c07c91:/$ wlr-randr HDMI-A-1 "Raspberry PI RPI MON156 81005568472 (HDMI-A-1)" Make: Raspberry PI Model: RPI MON156 Serial: 81005568472 Physical size: 350x190 mm Enabled: no Modes: 1920x1080 px, 60.000000 Hz (preferred) 1920x1080 px, 60.000000 Hz 1920x1080 px, 59.939999 Hz 1920x1080 px, 50.000000 Hz 1920x1080 px, 48.000000 Hz 1920x1080 px, 47.952000 Hz 1280x720 px, 60.000000 Hz 1280x720 px, 60.000000 Hz 1280x720 px, 59.939999 Hz 1280x720 px, 50.000000 Hz 1280x720 px, 48.000000 Hz 1280x720 px, 47.952000 Hz 720x576 px, 50.000000 Hz 720x480 px, 60.000000 Hz 720x480 px, 59.939999 Hz 640x480 px, 60.000000 Hz 640x480 px, 59.939999 Hz 640x480 px, 59.939999 Hz pi@3f4fb5c07c91:/$ wlr-randr --output HDMI-A-1 --on --transform 90 >>> screen returns <<< pi@3f4fb5c07c91:/$Please check I did the pull etc correctly

yes
this seems to become a never ending story …
With the last changes I wrote the display state (on or off) to a temp file so the labwc container knows the last state even after a restart. Problem now is the mm container, here the logs after restart:

Launching application.is missing), I think it is waiting for an active display …The Pir-Sensor which would active the screen again is running inside mm (which is not really running).
So I have no idea at the moment, maybe we have to live with the situation before, where after restart we need a sensor interval before the screen is blanked again.
