      Update to 2.4.0, and made the sudo nano /boot/config.txt dtoverlay=vc4-kms-v3d change.

      Shut down Pi, powered Pi back on, and now fails to boot, showing just a cursor top left of monitor.

        Comment out the dtoverlay=vc4-kms-v3d change, and Pi boots, MM starts OK.

        Does it matter where in config.txt that the new line is placed?

          Or…, is it best to use the sudo raspi-config /Advanced/… route?

            Did you remove these entries in the config.txt?

            display_rotate = 1
            avoid_warnings = 1

              display_rotate = 1 - is commented out (I’m happy with MM in landscape mode)
              avoid_warnings = 1 - line doesn’t exist.

                I had the same issue. I changed dtoverlay=vc4-kms-v3d to dtoverlay=vc4-fkms-v3d and was able to boot up again.

                  That doesn’t work for me, MM boots to a few lines about blocks, then nothing else.

                    Did you try the rasps-config tool to configure the GL driver?

                      No, because if that kills it, I don’t know how to bring it back - what file to edit etc…?

                        @richard238 It just modifies the config.txt for you in a save way. There is a bigger chance of you killing your pi doing it manually than using the config tool.
