Error log full of this error - gdk_monitor_get_scale_factor

Dotmatrix812

Hi

My error log is full of this error. And it is still coming. My background slideshow is sometimes. It working as well. Could be in relation to the error. But I am not sure. I have no glue where this error is coming from.

Anyone any idea what could help to solve this error ?

@Dotmatrix812 can you tell us a our your system?

I have never seen that error before

what module are you using for background?

Dotmatrix812

@sdetweil

It is a raspberry pi3 with raspian 11

I use MMM-BackgroundSlideshow

https://github.com/darickc/MMM-BackgroundSlideshow

I used the standard install from the magic mirror website.

What other information do you need ?

Thanks a lot.

@Dotmatrix812 what version of MagicMirror are you running?

you can see it in the logs, but maybe for you easier to do

cd ~/MagicMirror 
grep version package.json

edited: fixed typo

@Dotmatrix812 also can your show the config for backgroundslideshow

do you use any transitions?

Dotmatrix812

@sdetweil

The version is “version”: “2.27.0”,

The config for the background is


{
  module: 'MMM-BackgroundSlideshow',
  position: 'fullscreen_below',
  config: {
   imagePaths: ['modules/MMM-BackgroundSlideshow/fotos/'],
   randomizeImageOrder: true,
   slideshowSpeed: 60000,
   backgroundAnimationEnabled: false,
   gradient: [ "rgba(0, 0, 0, 0.5) 0%", "rgba(0, 0, 0, 0.15) 40%", "rgba(0, 0, 0, 0.15) 80%", "rgba(0, 0, 0, 0.5) 100%" ],
   horizontalGradient: [ "rgba(0, 0, 0, 0.5) 0%", "rgba(0, 0, 0, 0.15) 40%", "rgba(0, 0, 0, 0.15) 80%", "rgba(0, 0, 0, 0.5) 100%" ],
   gradientDirection: 'both',
    },
},

Thanks for your help

@Dotmatrix812 ok, 2.27 turns off use of the gpu by default

do this, open a terminal window

pm2 stop all
cd ~/MagicMirror 
export ELECTRON_ENABLE_GPU=1
npm start

and see if that message continues

you will have to minimize MagicMirror to get back to the terminal window
ctrl-m
should work

@Dotmatrix812 here also is an interesting cause

no monitor attached, Is this your case?

Dotmatrix812

@sdetweil

Seems so.

Strange that the time stamp is so different …

@sdetweil

No. Monitor is connected to the raspberry. Or could this happen when the monitor gets switched off via the MMM-PIR module ?

Sorry that my answers take so long. But I still need 3 reputations as new user.
