I cannot disable screen blanking with MagicMirrorOS
-
the setup is “Raspberry Pi OS Lite” with the normal docker setup and an additional labwc container
I have no idea what is happening. Sounds like the monitor totally cuts the connection to the pi after a while.
Maybe this post contains something helpful.
What is your wlr-randr command for waking up?
-
@smegbadger if you stop mmos does the screen still turn off overnight?
-
@sdetweil I stopped docker at 9:30 last night with
docker compose downleaving the screen at the magicmirror login prompt. This morning the screen was still showing the login prompt . MM was reinstated perfectly withdocker compose up -d --force-recreate. @karsten13 I notice there are now four objects that start:[+] Running 4/4 ✔ Network magicmirror_default Created 0.1s ✔ Container mm Started 0.9s ✔ Container init Started 1.0s ✔ Container labwc Started 1.0sSteve
-
the 4 objects are o.k., one network and 3 containers (
initis only for setting correct permissions in the mount folders, it runs for a very short time, you can disable it in the.envfile if wanted).Question: When the
failed to connect to displayoccurs, how do you get the screen back working? Is adocker rm -f labwc && docker compose up -dsufficient or adocker 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-randrcall every 30min. in thelabwccontainer. -
@karsten13 i have disabled the
initcontainer 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-recreatealso works butdocker compose up -don it’s own doesn’t). I am running it today with theMMM-Universal-Pirmodule 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.

@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
.envfileLABWC_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
labwcbut when i looked this morning there were some 40 calls towlr-randrthat had failed. If they are every 15mins that’s about 10:00 it failed. I will make a more accurate observation tonight -
unfortunately that change did not prevent the display from dropping
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
wlopmto 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.jsmodule: "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 labwcthewlr-randrcommand was failing (still being triggered every fifteen mins) which suggests the connection between theMMM-Universal-Pirand 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 90to theonCommandto get my screen rotation.magicm@magicmirror:/opt/mm/mounts/config $ docker logs labwc HDMI-A-1 "Raspberry PI RPI MON156 81005568472 (HDMI-A-1)" Make: Raspberry PI Model: RPI MON156 Serial: 81005568472 Physical size: 350x190 mm Enabled: yes Modes: 1920x1080 px, 60.000000 Hz (preferred, current) 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 Position: 0,0 Transform: 90 Scale: 1.000000 Adaptive Sync: disabled failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display failed to connect to display magicm@magicmirror:/opt/mm/mounts/config $ docker exec -it labwc bash pi@c7c64f70849e:/$ wlr-randr failed to connect to display pi@c7c64f70849e:/$Steve

@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.
