Applied change to config.txt, MM fails to boot.
-
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-v3dtodtoverlay=vc4-fkms-v3dand 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.
