Black screen

[r3zi3lr]

Hi,

I’ve managed to install the Module but I’m getting just a black screen for the module.

Have I forgotten to install something?

Code for my config.js below:

module: "MMM-TomTomTrafficIncidents",
			position: "center",
			config: {
			key: "",
			lng: -123.1139529,
			lat:  49.2608724,
			zoom: 11,
			height: "500px",
			width: "800px"

Thank you.

open the developers window, ctrl-shift-i on the keyboard, select the tab labled ‘console’ and scroll up to see any errors… u can also filter by module, by placing some part of the module name in the filter field, like ‘tom’

please use code block markers for config items… select the text, and push the </> button above the editor

Thank you for the quick response.

maps-web.min.js:1 Error: Failed to initialize WebGL

to test do this

cd ~/MagicMirror
node node_modules/.bin/electron https://webglreport.com/?v=1

it may be a hardware config issue for the display driver (I don’t know how to fix it myself), google may help, other users too…

[r3zi3lr]

@sdetweil

Managed to fix it myself using the below:

Console: sudo raspi-config Under “7 Advanced Options” / “A7 GL Driver” pick “G2 GL (Fake KMS)”

Desktop: Preferences / Add Remove Software search for “Chrome” and pick “WebDriver driver for the Chromium Browser”, click “OK”

[sdetweil]

@r3zi3lr awesome!

[Travelbacon]

Nice work. I will also add in my documentation that Fake KMS must be set.

Btw: Did you check the Pi settings on:
https://github.com/MichMich/MagicMirror/wiki/Configuring-the-Raspberry-Pi ?
There might be a change that you can have other options.

@MichMich The FAQ seems to be outdated. In the newest Raspberry Pi OS (Raspbian) the whole raspi-config has changed for the driver settings.
