<![CDATA[TOTAL BEGINNER: Exit Code 512 RPi 3 A+ Black Screen and Countless Issues Downloading and Running MagicMirror]]>Hey all! Brand new to coding and the raspberry pi system. I apologize if this has been asked but my level of knowledge on this makes it difficult to follow on the forums as I have been trying to understand them for the past 2 days. Would love to learn more on how to diagnose on my own and commands/pathways to do so. But right now I need step-by-step help please.

Been enjoying learning some basic coding but getting frustrated as I run into issues either installing dependencies or running the mirror (as it only goes to black screen). I have tried multiple fresh flashes, disabled proxies, toggled OpenGL, but I still cannot run the MagicMirror. I have VNC and SSH enabled and followed all of the manual install steps including updating NPM and nodes. This morning I finally got it all downloaded with no issues except now running it does not work. On running magic mirror, it does not register as a tab “Magic Mirror” but rather just says “Electron”. I get the below error:

b083rt@raspberrypi:~/MagicMirror $ npm run start

I believe this code tells you the version of software if this helps:

b083rt@raspberrypi:~ $ cat /etc/os-release

export ELECTRON_DISABLE_GPU=1

then execute
npm start

this should turn off the electron use of the gpu chip.

if you use a script, u can add this before it’s npm start

also, run my install script it does all the setup.

flash again then run install
