Black Screen after installing fonts-noto-color-emoji

[aunrea]

@sdetweil I think when I tried to install mmpm that it didn’t install correctly. I did it again and everything seems fine except I still have a black screen. But somehow in the web using the ip address it loads fine. Why would I get a black screen on the pi but everything working on the web? I even made a change to make sure it wasn’t cached and the change showed up so it’s new.

I have been getting the following error mm-error.log:

@aunrea are you running the 64 bit raspi os?

this is a configuration problem when using the Vulcan video driver.

[aunrea]

@sdetweil I am running the 32 bit raspi os. I used the official raspberry pi imager to create it.

[aunrea]

I think it’s a GPU issue. Could it have been a bad install of the os? Should I reinstall?

[sdetweil]

@aunrea I do not know

[aunrea]

Ok I am going to try a new install on my raspberry pi 4, instead of the 3B I have been using.

[arosenhave]

@aunrea any luck resolving this issue?
I have a fresh install of MM on an RPI4 (Rasbian OS 32bit) and get the same problem when installing MMM-Face-Reco-DNN. Only errors I have in the logs are the same GPU related ones.

And the strange thing is that I have the exact same setup on a different SD card done 6 weeks ago. And that works perfectly. It reporst my MM is outdated, but I don’t dare updating it now.

[sdetweil]

@arosenhave depends on which video driver is enabled in /boot/config.txt

edit the script which starts MM
and add

export ELECTRON_DISABLE_GPU=1

before the
npm start
line

[sdetweil]

@arosenhave if u want to upgrade, use my script
see
https://github.com/sdetweil/MagicMirror_scripts

and backup
