Blank screen issue ( another one again ) after one hour or so...
-
Hi to all members!
First I want to thank all contributor for the Magic Mirror project. I really enjoy this project to build my own mirror and learn new things.
I have a pi 3b+ running on the latest OS :
stretch V9.6I have installed MM and followed all documentations then implemented a few modules.
the defaults one they are working fine ( some are commented such as alert and notifications (For debugging the blank screen issue I have and make sure the cause was not those modules)
MMM-AssistantMk2 & MMM-Hotword ( perfectly works )
MMM-NowPlayingOnSpotify working fine but commented for as well because getting too much errors ( when nothing was played )
mmm-systemtemperature : Works OK
MMM-DarkSkyForecast :Works OK
MMM-Hue : Works OK
MMM-Traffic : Works OK
MMM-PIR-Sensor (To turn off&on the HDMI Port) : Works OKYou will tell me all “works OK” so what’s wrong with you guy :)
Well after I start my MM all is “work ok” (Again)
The Pir sensor delay works and well shutdown the HDMI port and it comes back when a movement is detected. My delay is set to 10 mins and if I come back after 15mins the screen is back ON, So far so good .Now my issue : When I come back after a while let’s say an hour or more, the PIR sensor turn ON the HDMI port and my screen goes on.
Then surprise I get a blank screen.
I know I’m not in screen saver mode because after a VNC connection I see the little popup on screen and I can see the mouse moving as well.
My conclusion is that the MM is in a kind of “sleep” mode waiting to be wake up.
I can bring the MM modules back on screen for example by giving input via the Hotword/assistant module so when I say “Jarvis” the hotword is detected and MM & all modules directly come back on screen.
No error in the MM error log from PM2 nor in the out file.
Dev mode ( Shift CTRL I ) show me that the modules are still well receiving notification from other modules )Before posting this thread here as I said I read the full installation documentation and more. I did many research for a similar problem and didn’t find . I looked at many places and applied several solutions. Unfortunately without success ).
It look like it’s a matter in the MM code itself ( But I maybe wrong I do not want to bother anyone by saying this ) Just a personnal thought.
Here is my setup :
/etc/lightdm/lightdm.conf[SeatDefaults] ( I had to create this entry in the file ) xserver-command=X -s 0 -dpmsAs well added to
[Seat:*] ( which was existing prior editing the file ) xserver-command=X -s 0 -dpmsJust in case ( but I have added this after and that didn’t help )
The file /etc/xdg/lxsession/LXDE-pi/autostart
@pcmanfm --desktop --profile LXDE-pi @xscreensaver -no-splash point-rpi @xset s noblank @xset s off @xset -dpmsAnd /etc/xdg/lxsession/LXDE/autostart
@lxpanel --profile LXDE @pcmanfm --desktop --profile LXDE @xscreensaver -no-splash @xset s noblank @xset s off @xset -dpmsI didn’t make it in /.config/lxsession/LXDE-pi/autostart because when creating this file my system boot in openbox and not in desktop session.
And I want to keep the desktop for other reason.I installed xscreen and turn of powersaving on screen and screen saver.
My config.js file :

I didn’t use the OpenGL driver in /boot/config.txt as in was generating error in the logs, and my pi is Fan cooled So I don’t worry for now about system temp ( always around 50°C) and CPU usage ( around 40% when MM + VNC are running )
So if anyone have clue / good question to ask my to help me dig out this issue and resolve it you are most that welcome !!! I hope that this post was not too long but I wanted to give as much details as I can.
If you need any other info feel free to ask me.
Thank you again for all your work and help .

Ok Great ! That was the issue !
Placing the timer to 0 prevent the module to be suspended .Now I would like to put this back in the code so the modules in suspended mode that is great as indeed I don’t need them update when the screen is Off but i’d like to resume with the onDetected when motion is detected by the PIR module ?
Is it possible to Sync the Idle and onDetected with the PIR Module ?
Thanks .

disable the updater module
start the MM withnpm start dev
and select the console tab… make sure its scrolled down all the way
then repeat your test cycle
see if anything shows on console when the black screen is up -
@ejay-ibm said in Blank screen issue ( another one again ) after one hour or so...:
// {
// “module”: “updatenotification”,
// “position”: “top_bar”
// },Is that the module you are talking about ( as you can see it’s already commented ) ? If not how do you disable the updater module ?
I’m running dev mode now waiting for the issue to reoccur.
thanks

Once the screen goes OFF
module.js:198 MMM-Hotword is suspended. module.js:198 MMM-PIR-Sensor is suspended. module.js:198 clock is suspended. module.js:198 MMM-AssistantMk2 is suspended. module.js:198 MMM-Traffic is suspended. module.js:198 MMM-Hue is suspended. module.js:198 MMM-DarkSkyForecast is suspended. module.js:198 mmm-systemtemperature is suspended. module.js:198 newsfeed is suspended. received TRAFFIC_COMMUTE MMM-Traffic.js:273I Get now blank screen . Nothing happens in the log/dev console
Now I moove and screen goes ON , but MM still blank I say “Jarvis” and the console logs shows.
clock received a module notification: ASSISTANT_ACTIVATE from sender: MMM-Hotword module.js:154 clock received a module notification: HOTWORD_PAUSE from sender: MMM-AssistantMk2 module.js:154 MMM-Traffic received a module notification: HOTWORD_PAUSE from sender: MMM-AssistantMk2 module.js:154 MMM-Hue received a module notification: HOTWORD_PAUSE from sender: MMM-AssistantMk2 module.js:154 MMM-DarkSkyForecast received a module notification: HOTWORD_PAUSE from sender: MMM-AssistantMk2 module.js:154 mmm-systemtemperature received a module notification: HOTWORD_PAUSE from sender: MMM-AssistantMk2 newsfeed.js:340 newsfeed - received notification: HOTWORD_PAUSE newsfeed.js:391 newsfeed - unknown notification, ignoring: HOTWORD_PAUSE module.js:154 MMM-Traffic received a module notification: ASSISTANT_ACTIVATE from sender: MMM-Hotword module.js:154 MMM-Hue received a module notification: ASSISTANT_ACTIVATE from sender: MMM-Hotword module.js:154 MMM-DarkSkyForecast received a module notification: ASSISTANT_ACTIVATE from sender: MMM-Hotword module.js:154 mmm-systemtemperature received a module notification: ASSISTANT_ACTIVATE from sender: MMM-Hotword newsfeed.js:340 newsfeed - received notification: ASSISTANT_ACTIVATE newsfeed.js:391 newsfeed - unknown notification, ignoring: ASSISTANT_ACTIVATE module.js:154 clock received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword module.js:154 MMM-Traffic received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword module.js:154 MMM-Hue received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword module.js:154 MMM-DarkSkyForecast received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword module.js:154 mmm-systemtemperature received a module notification: HOTWORD_SLEEPING from sender: MMM-Hotword newsfeed.js:340 newsfeed - received notification: HOTWORD_SLEEPING newsfeed.js:391 newsfeed - unknown notification, ignoring: HOTWORD_SLEEPING module.js:205 clock is resumed. module.js:205 MMM-AssistantMk2 is resumed. module.js:205 MMM-Hotword is resumed. module.js:205 MMM-Traffic is resumed. module.js:205 MMM-Hue is resumed. module.js:205 MMM-DarkSkyForecast is resumed. module.js:205 MMM-PIR-Sensor is resumed. module.js:205 mmm-systemtemperature is resumed. module.js:205 newsfeed is resumed.So it look like the suspended state create the blank screen. (am I right ? :/ )
If yes Now the question is , how to prevent the modules to be suspended.
Is that because of the PIR module ?thanks

Searching for similar log in other thread I found someone saying :
“It might be due to “onIdle” and “onDetected” features. Disable them”
So I have added to my config.js in the MM assistant moduleonIdle: { timer: 0, // if you don't want to use this feature, just set timer as `0` or command as "" command: "HIDEMODULES" },I’m testing and will report results.

Me again
I Would Say that you should mark the post as solved As We have root cause here.
I have created that githttps://github.com/paviro/MMM-PIR-Sensor/issues/73
To get some help from paviro and see if the ondetected function of MK2 assistant could be implemented in the PIR module so they could be kind of sync.Thanks to @sdetweil for driving me in the right debug way for finding the root cause of the problem.

Hi @ejay-ibm did you manage to fix the issue. i have the same issue with the PIR Module. Sometimes the screen wakes up but its blank and i have to restart the pi.
