MagicMirror screen goes black

DavyC · Feb 15, 2019, 5:57 PM

Hi all,

my magic mirror uses following modules : newsfeed, MMM-DarkSkyForecast, MMM-ethereum, MMM-GoogleMapsTraffic, MMM-LICE

Following issue is occuring after a “while”. This can be 1 day, 1,5 day, more, less…

The screen becomes black. Only thing I can do is ALT-TAB, try to open a command prompt and press CTRL-C to exit the mirror.

In the beginning I thought the Mirror went into sleep, but now I found out there’s a JS stack trace.

**==== JS stack trace =========================================

Security context: 0x3913fa4d <String[21]: http://localhost:8080>
2: emit [events.js:193] [bytecode=0x3664d749 offset=200](this=0x6d485461 ,type=0x4b2dd285 <String[14]: document-start>)

I have no idea on what to search to find more help on this.
It looks like an issue in the Google maps ?

Any idea what can be wrong please ?

Best regards and thanks in advance,

Davy

@davyc I think your suspicion about Google Maps might be correct. I would start by disabling the MMM-GoogleMapsTraffic for a few days to see if the issue goes away.

Then we ca start digging in to the module to see what might be causing the issue.

If the problem doesn’t go away, then repeat disabling with the other modules one at a time until you have a working setup. The last one that you disabled is the culprit, and we can start troubleshooting from there.

Sorry to hijack the thread but I have the same problem. I’ve run a log and it seems that MMM-NowplayingSpotify causes the error. Do I have to disable the Spotify or can it be solved?

@hallonpaj said in MagicMirror screen goes black:
I don’t think so. It looks like there’s a temporary problem with Spotify. Since the problem is on their end, it most likely will be resolved soon.

From your logs:

message: ‘502 - “\n\n\n502 Server Error\n\n\n
Error: Server Error
\n
The server encountered a temporary error and could not complete your request.

@bhepler Alright! Thanks for answering :)

but the module could be changed to handle that error and not crash

DavyC · Feb 20, 2019, 8:01 AM

Will try to do that soon. I do not have a lot of time to test, so there will be some delay :-)

Cr4z33 · Feb 26, 2019, 6:34 PM

@davyc yes please fix it as I am getting the same issue (actually since today only although I got it running perfectly for weeks… :thinking_face: )

Isn’t this supposed to cover such occasions as that and restart the server.
I only have a Pi-Zero so far so have never tested the effect with the normal Electron setup just Chromium standalone kiosk style.
So I don’t actually no if or what the mechanism to restart the browser (Electron) is.
If it doesn’t refresh via MMM-WatchDog you can always use xdotools to send keys to an Xwindow and all you need to do is a ‘ctrl+F5’ which is a refresh and drops the cache so all is effectively loaded as new.

sudo apt-get install xdotool

Then with ~/MagicMirror/run-start.sh add a line and nano xdotool.sh and chmod a+x xdotool.sh

if [ -z "$DISPLAY" ]; then #If not set DISPLAY is SSH remote or tty
	export DISPLAY=:0 # Set by default display
fi
sh xdotool.sh &
electron js/electron.js $1

With xdotool.sh being something like this

export DISPLAY=:0
export XAUTHORITY=~/.Xauthority
sleep 10
xdotool search --onlyvisible --class "chromium" key ctrl+F5  -v 2>&1 | logger &

Dunno what the Electron class is but really its just Chromium in a wrapper so expecting that actually that will work.
If not you will just have to do a bit of testing to find the class or PID of electron http://manpages.ubuntu.com/manpages/trusty/man1/xdotool.1.html

Replied again cursed by that akismi bot troll thing.

PS still setting it up but just monitor your logs.

Create a shell script with something like

 tail -fn0 logfile | \
while read line ; do
        echo "$line" | grep "pattern"
        if [ $? = 0 ]
        then
                ... do something ...
        fi
done

Maybe with a --retry to the tail command, or use -F instead of -f

Tack it onto your electron log and do the above xdotool.
