MM2 screen goes black after a couple of hours.

reilley

Hello,

I’m on v2.28.0 , running on an RPi 3 model B rev 1.2 running Bullseye v11.

The screen saver is not activated on the Raspberry Pi and I don’t use screen blanking modules. I do use MMM-Wallpaper since sky setup is not a mirror. For some reason after a couple of hours, the MM screen will go black but I can see the mouse pointer. I can hit CTRL-Q and exit MM2 and then restart it, but it’s inconvenient to do that.

Has anyone else seen this issue and if so, how did you resolve it? I’m not seeing any error messages upon exit of the application.

@reilley can u tell me what other modules you use?

easy list from the commandline

grep module:  ~/MagicMirror/config/config.js | uniq | sort -h

I See this happen also on my mirror from time to time.
I have not verified it, but to me it seems a memory issue.
I faced it often when loading many background pictures in short intervals. I changed my interval to a longer period and also resized some images.
That helped a lot.

Hi Sam! Sorry for the delay but I don’t get alerts from this board for some reason.

To answer your question, I use these modules:

Alert
Calendar
Clock
MMM-CalendarExt3
MMM-GoogleCalendar
MMM-Rain-Map (currently commented out)
MMM-SmartWebDisplay
MMM-Wallpaper
Newsfeed
Update notification
Weather

Hi Eli! I increased the time from every minute to every two minutes to see how that works out. I haven’t tried resizing the files but that sounds like a great idea.

Thanks!

@reilley I had a bug in one of MY modules that allocated space for an image, but didn’t release it, and eventually the browser died. black screen

took me a year to find it as it appeared random…
random was how many images it actually displayed, depending on how many times it was active… (when the mirror went to sleep it stopped processing and resumed on wakeup… so every time I went down the hall it would wake up again… )

but I haven’t seen that problem with any of the modules you listed
