Magic Mirror Blanks Several Hours

[MadScientist]

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.

[StrIIker]

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).

[sdetweil]

@striiker is this version 2.4.1?

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

I would comment out that module

[MadScientist]

@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).

[StrIIker]

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

[MadScientist]

@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.

@sdetweil So I’ve updated my MagicMirror today with NPM update and NPM upgrade and my mirror is now black when I load it. My Mirror is pretty busy with NNOA3, video window from MotionEye and a few of the UK train apps. I was going to thin it down to see if that fixes it but thought Id check if anyone else found a fix yet.

[Graham Rich]

I’m not sure if my issue isnt an update failure. Im getting this message on upgrade

@graham-rich to update your MM installation you have to enter your MM directory and run git pull && npm install. Looks like you tried to update npm instead.

[Graham Rich]

Just run NPM install in the MagicMirror directory and seems to have fixed it. Was suggestion from NPM audit command
thanks for suggestion tho

[chief]

I’m having trouble with this as well - blank screen for the past day no matter what I try to do. Now when I try to git pull && npm install, I get the following errors:

Any help??

[MadScientist]

Why are you running the update command with sudo?
Does your mirror work but it blanks the screen after some hours or is it always black?

[chief]

@madscientist It was always black - if I don’t run with sudo it quits almost immediately. I’m not sure exactly what the issue was, but I went ahead and restored a backup from 2.4.1 and it’s working fine now (removed the update alert on the top bar).

[StrIIker]

I’m still having the issue where my screen blanks (modules stop loading) after about 5-6 hours. I perform a Ctrl-r to reload and it continues. Has anyone else figured out a cause or a solution? I’ll have to add several more cron jobs to reload modules periodically. I am not running anything beyond the core modules at present. I even performed a fresh install and still see this happen. I can’t see this being normal or people just tolerating it…

Thoughts?

If you need to run this as sudo then your installation probably has root as the owner of the files. A simple way to check this is log in as pi and type cd ~ and then ls -al you should see the list of files and directories and a column of pi pi (shows owner and group membership of the file or directory). If you see a lot of root root then you ran something which changed ownership of these files and directories…

If you have a permissions issue, you can fix it easily by typing:

sudo chown -R pi:pi /home/pi

This will change owner and group membership to pi

@striiker Could it be the screensaver? Have you tried updating to 2.5.0 or downgrading to 2.3.x? I am pretty sure I didn’t have the problem with 2.3. In my case it’s enough to reload the MM only once a day. Also I had noticed that my Pi was reeeeeeeaaaaaaallllllyyyyyyy slow when connecting via shh after the screen blanked. Slow to the point I thought it crashed. Pretty sure it was a memory leak or so.

I haven’t updated to 2.5 yet as I want to wait and see what problems other users experience :face_with_stuck-out_tongue_winking_eye:

Well, I have disabled the screensaver via config settings as advised by several of the tutorials for setting up the mirror. Plus, if it were blanking or a screensaver, it would wake when I move the mouse or type. When I try to type etc, nothing shows, just the black screen. Ctrl-R or CTRL-Q works.
I am on the latest (2.5) and have not tried downgrading. I assume that would require a full wipe and re-install but may be worth trying… When I experience this condition, I see no slowness while connected to ssh. I’m sure this is some odd leak which crashes some aspect of whatever displays the modules over time. I’m just surprised that nobody else (in any significant number) is experiencing this. It happens with a new everything… (Pi3B, latest firmware and latest mirror version)
