Magic Mirror Black Screen after "pm2 start mm"



  • Hey everyone! First time posting, so please be gentle…

    Have had my MM and modules running for 3+ months at this point - no issues. I had this Pi running in a case for this entire time, however, decided to remove it and put the case to use for another Pi while I have another on order (the other needed the cooling more than this one).

    After removing the case and starting back up - no issues. Raspberry Pi loaded to desktop no issues. The magicmirror service is set to start after x amount of seconds (forgot off-hand) but first thing I noticed is once the module loaded, all I get is a black screen. Returned to desktop using “pm2 stop mm”, which works successfully. If I run “pm2 start mm”, the service begins to run, but enters a black screen again. This was working 10 mins ago before I shut down the Pi for case removal.

    I’ve ran the following commands, thinking updating my Pi would help (it’s been a while) but with no avail:
    -sudo apt-get update
    -sudo apt upgrade
    -sudo apt install

    Raspian Stretch 9.9

    Please let me know what information I can provide to help troubleshoot! Any help is appreciated!

    One more piece of information:

    I took a backup of my config.js file (/home/pi/MagicMirror/config) and then removed it. I then took the sample “config.sample.js” and used that as my config.js – this worked. Loaded fine. Then I removed this same config, made my backup config my actual config.js, and that worked ONE time. After I quit and then tried reloading, I got a black screen again. Is this some sort of RAM issue?



  • I apologize for the above log.

    Below are the Pm2 logs for starting both the “config.sample.js” (which works) and the “config.js” (which does not work)

    Thanks!



  • So I’m assuming from my own readings, it would appear that the Pi is expecting Electron-v3.1-linux-arm-glibc but that is not found. I tried rebuilding my /home/pi/MagicMirror/modules/MMM-AssistantMk2/node_modules directory but ended up accidentally deleting it.

    So now the same applies, it’s expecting Electron-v3.1-linux-arm-glibc, however it finds “[node-v64-linux-arm-glibc]”. I tried npm rebuild, but no avail. I’m assuming all I need to do is rebuild that node_modules directory and get it to Electron-v3.1-linx-arm-glibc?

  • See the instructions in the MMM-AssistantMk2 module readme.md on how to fix the gprc issue



  • @sdetweil

    I’m assuming this is what you’re referring to?

    "grpc Electron-rebuild or Raspbian Buster issues. (on Raspbian Buster) Downgrade your gcc to gcc7. (default of Buster would be gcc8)

    sudo apt-get install gcc-7
    sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 10
    sudo update-alternatives --config gcc

    Then select gcc-7

    Then try electron-rebuild again."

    Just for confirmation - would this rebuild my node_modules directory? The most recent log I posted shows I don’t even have any electron version. I will attempt this later tonight.

    As a side question - if I delete my Mmm-assistantmk2 module and rebuild it from scratch, would that affect the configurations of my mirror at all? Correct me if I’m wrong, but couldn’t I just reinstall this module since the config.js just references this module?



  • @Parity no, but u will end up at the same recovery steps



  • @sdetweil okay thanks. So just try what I posted above and it will automatically rebuild electron in the process? If not, just do Mmm-assistantmk2 from scratch?



  • Had the same problem, change directory to MagicMirror and execute npm start. Hope it help
