      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 )

            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:

              > magicmirror@2.4.0 start /home/pi/MagicMirror

              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
