One way is to go to that link I gave you and download the version you want and install it manually.

Bumping this because I’m also having issues. A lot of time on google says it’s not just a MagicMirror issue, but lots of people have problems with the OpenGL drivers. My screen is blanking after some time no matter what, but I also found the hard way that it messes with tvservice (like the Remote Control module uses) – turning my HDMI off straight up insta-shut down my pi! Gonna have to keep researching for sure.

I just updated and this is shown at the end of the install.

MagicMirror installation successful!

> cd fonts && npm install

I applied

dtoverlay=vc4-kms-v3d

to the config.txt ( also tried with fkms)

Reboot and I get a black screen.

When I remove dtoverlay=vc4-kms-v3d then the mirror boots up.
Any suggestions?

Just found your guide: https://forum.magicmirror.builders/topic/5274/how-to-manually-install-mm-on-your-pi-for-absolute-beginners

Going at it now and see if it works - thanks for the patience and writing that guide!

You’re welcome, sir. :-)

Got my mirror working again. Had to go over the opengl drivers again and using the fake kms driver did the trick. However one problem remains, i had to also disable the MMM-Pir-Sensor module because that was messing with the system. But also my custom.css is not being used atm, and i cant figure out why its not grabbing it.

[Kimzer]

Anyone else struggling with using MMM-Pir-Sensor after the new update?

[thenameiwantedwastaken]

Yes, I am having the same black screen. I have to disable PIR to be able to use MM at all. I also noted that after I installed PIR I could no longer SSH into the Pi from my desktop computer, whereas I could from my mobile phone. Anyway, the black screen is the main concern right now. I’ll post if I discover anything helpful.

Not sure if I’m having the same issue, stupidly updated electron as npm was claiming 1.7.13 had a critical vulnerability (after installing MMM-voice) Then got the backscreen issue. rolled back electron to 1.7.13 & the issue persists.

Node v9.11.1
npm 6.1.0

Thought I’d uploaded the log file but not sure if others can see it. That snippet below is the first error after ALL_MODULES_STARTED

Any pointers as to how to get it working again? It was working perfectly before MMM-voice & buggering around with electron.
Tried a fresh install with the same result :(
