Magic Mirror Blanks Several Hours



  • Hello,

    I have a magic mirror and after a period of several hours, the screen goes black. The mouse still works as I can move it and see the cursor. Clicking the mouse does nothing nor does hitting random keys. I can hit Ctrl-Q to exit Magic Mirror and I get the desktop back. A few seconds later pm2 kicks in and reloads the magic mirror. I experience this when connecting via VNC as well as locally at the system (obvious but mentioning for thoroughness). I also disabled screen blanking and screensaver per the install instructions.

    This is a new install on a Pi3B. I would greatly appreciate advice on how to approach this. Thank you in advance!



  • I have the same problem. A Ctrl-R helped getting the modules back but I didn’t like doing it at least once a day. Therefore I created a cronjob that reloads the MagicMirror everyday at 6am. Haven’t seen a black screen since then.

    Not a fix but a work-around.



  • Ahh, that’s the issue! The modules must get stuck and no longer refresh. Has anyone else run into this issue and found a cause / solution? My issue crops up more often than once per day and I’d prefer to get a permanent fix for this. I don’t have any unusual modules loaded (actually it has been happening from day one while I have been slowly working on it so this has been happening with a fresh install).



  • @striiker is this version 2.4.1?

    The update module was throwing an error causing the black screen.

    I would comment out that module



  • @sdetweil
    That didn’t help in my case, hence the work-around with the cronjob. But it’s true that everybody should first try to disable the update module in their config.

    I am at the latest build (2.5.0) although I installed Magic Mirror from the previous version and have the update module running.

    I was unaware of the suggestion to kill the update module. I have removed it from my config and will monitor the status. Thank you for the suggestion (and @sdetweil )! Any other best practice suggestions which I should consider? I have just done the base install and modified weather icons / details and also installed Alexapi (yet to work on that module as I am still trying to understand if I should also install either MMM-Alexa or MMM-Awesome-Alexa too as I am not clear on how these all work).



  • @madscientist Could you please share what you use in your cronjob to reload the modules? Thanks!



  • @striiker 0 6 * * * pm2 reload mm
    It reloads my mm.sh script every day at 6am. Working perfectly fine for quite some time now.

    I’m in the same boat as @MadScientist in that my module rotation still dies necessitating a restart of the modules. Canceling the update check did improve the situation in that it apparently does not crash out as often.
