@sdetweil @mumblebaj
Awesome support!

I just added it to the package.json
“scripts”: {
“start”: “DISPLAY=”${DISPLAY:=:0}" ./node_modules/.bin/electron --disable-gpu js/electron.js",
“start:dev”: “DISPLAY=”${DISPLAY:=:0}" ./node_modules/.bin/electron js/electron.js dev",

and have one error left

0|mm | [11202:0114/154643.064204:ERROR:sandbox_linux.cc(376)] InitializeSandbox() called with multiple threads in process gpu-process.

Funny thing is that i have the same error on another config.json without Face-Reco and the mirror is working there.

@sdetweil Thank you!
Do you mean package.json ? I dont find a file called pancake.json

@sdetweil said in MagicMirror stays black after adding Face-Reco-MMM:

pm2 logs --lines=50

With it I get an output

@sdetweil Thank you for your rapid response!
Unfortunately I get the same output:
[TAILING] Tailing last 15 lines for [MagicMirror–lines=15] process (change the value with --lines option)

I have this since 1 hour displayed in my terminal

Hi All

I’m trying to build my first Mirror with Face-Reco Module from Nischi.
I followed the Guideline 1:1 but after adding the Module to config.js, the Mirror stays only black. Even when I mapped all Modules to “show always”

When i use the Tools which are provided, my PiCam recognizes our faces without any problem.

I’m working with a Raspberry 3, Model B+, OS is Buster.
When i run npm run config:check I get 0 errors which doesn’t help me for troubleshooting.

When I remove the Module, the Mirror is working again without any issues.
I have tried to get logs thru pm2 log MagicMirror but this also don’t work.

This is the Module which I use
https://github.com/nischi/MMM-Face-Reco-DNN

Somebody any input for me?

Cheers
Chris
