Black screen after MM v2.4.0 update.

[joela85]

Black screen after updates. Followed the commands below.

sudo nano /boot/config.txt

added this to the bottom and saved.

dtoverlay=vc4-kms-v3d

then…

nano ~/.config/lxsession/LXDE-pi/autostart

added this to the bottom and saved

@xrandr --output HDMI-1 --rotate right

Then the install…

cd MagicMirror

and

sudo git pull && npm install

successful install and rebooted to see a black screen.
Have I missed anything?

According to another similar thread please set this instead:

dtoverlay=vc4-fkms-v3d (with an additional f )

[joela85]

Thanks for the reply, I will try that when I get home.

I also have a black screen.
Tried both options

dtoverlay=vc4-fkms-v3d

and

dtoverlay=vc4-kms-v3d

I have a similar problem, after starting the MM the screen freezes, only way to unfreeze it is to close electron. Have tried both options too.

After enabling either of the OpenGL drivers i get the followed errors:

Edit: MM works without any OpenGL Drivers, but CPU usage is pretty high and the Node errors are still there.

After 2.4.0, Asus Tinker Board cannot display MM. I think it might be related with this openGL issues. Is there any way to solve this?
ATB has no openGL desktop driver like vc4-kms-v3d. Fake vc4-kms-v3d does not help.

I can’t access my mirror remotely anymore. Will I need to format my sd card and try again?

I am having the same issues and tried alot right now.

Tried the
dtoverlay=vc4-fkms-v3d as well as dtoverlay=vc4-kms-v3d as well as deleting that phrase

I downgraded electron to npm install electron@1.4.15 since i found that helped in the V2.30 problems.

I cant currently show the log from starting MagicMirror since i remotly access it and the MM just goes “all black” over the remote-access-page and I cant close it.

I really just want to downgrad the MM to 2.3 since it worked absolutly fine with it…

Additional software I use is MM-PIR
