Black Screen after installing fonts-noto-color-emoji

@aunrea yep

the link I gave u had the instructions in the 1st post

find the message, get the name, install it in the module folder

there are more than one library file missing. depends on the module… so I have to teach you the process.

@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 It reporst my MM is outdated, but I don’t dare updating it now.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
