Black Screen after installing fonts-noto-color-emoji
-
@aunrea are you running the 64 bit raspi os?
this is a configuration problem when using the Vulcan video driver.
-
@sdetweil I am running the 32 bit raspi os. I used the official raspberry pi imager to create it.
-
I think it’s a GPU issue. Could it have been a bad install of the os? Should I reinstall?
-
@aunrea I do not know
-
Ok I am going to try a new install on my raspberry pi 4, instead of the 3B I have been using.
-
@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 It reporst my MM is outdated, but I don’t dare updating it now.
-
@arosenhave depends on which video driver is enabled in /boot/config.txt
edit the script which starts MM
and addexport ELECTRON_DISABLE_GPU=1
before the
npm start
line -
@arosenhave if u want to upgrade, use my script
see

@sdetweil This made no difference, I’m afraid :(
The strange thing is that for a split second I can see the other modules loading and displaying and then it all goes black. Like the MMM-Face-Reco-DNN somehow loads in front of everything. If I remove this module from config.js everything displays fine. I have checked the config.js for syntax errors and it reports nothing.
-
@arosenhave yes, reco hides everything til u identify thru the camera yourself
then it shows the modules marked as visible for your profile/module classes config
-
@arosenhave I would need to see the output of the npm start.
black screen is usually a module crash or missing dependencies
-
@sdetweil I am so sorry. I don’t know how I missed this from one installation to another but feel truly ashamed. What happened is that I used a copy of config.js that I thought was the one working from previous install. But it was missing the classes clause to show the modules.
Again, so sorry and super grateful for putting me on the right track :)

@arosenhave glad u found it!
