Applied change to config.txt, MM fails to boot.

[Richard238]

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

[JoeFranz]

Did you remove these entries in the config.txt?

display_rotate = 1
avoid_warnings = 1

[Richard238]

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.

[Richard238]

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?

[Richard238]

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

[MichMich]

@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.

[Richard238]

Ok, when I get time, I’ll create a backup of the MM SD card first, and then try the GUI config tool.

Thanks.

Mine installation was successful.

First I update rp3
#sudo apt-get update
#sudo apt-get upgrade

#cd MagicMirror/
#git pull && npm install

#cd
#sudo nano /boot/config.txt (add in config.txt and save)
dtoverlay=vc4-kms-v3d
display_rotate=1

#sudo raspi-config
Advanced Options
GL Driver
G1 GL (Full KMS) OpenGL desktop driver with full KMS

#sudo reboot

***I cannot remeber if I did this process or not
#sudo nano ~/.config/lxsession/LXDE-pi/autostart
@xrandr --output HDMI-1 --rotate right (add to autostart)

[Richard238]

Done through raspi-config, seems ok, boots and runs fine.

sudo vcgencmd measure_temp

shows 56.9C
