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!

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.

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

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
