Hi the solution is already at:
Just tu sumarize:
add to config.txt (or better to userconfig.txt):
dtoverlay=vc4-kms-v3d-pi5
Below will make the Touch Display plugin starts to work:
2.1
Disable Touch Display plugin
2.2
As a root (not sudo, root):
cat >> /etc/X11/xorg.conf.d/99-vc4.conf <<EOL
Section "OutputClass"
Identifier "vc4"
MatchDriver "vc4"
Driver "modesetting"
Option "PrimaryGPU" "true"
EndSection
EOL
2.3
Reboot
- If you like to rotate the screen:
Either by manual command (it will gone after boot):
xrandr --display :0 --output HDMI-1 --rotate right
(right can be changed to left depending which direction you need)
or to have persistant solution:
mkdir /home/volumio/.config/openbox
cat >> /home/volumio/.config/openbox/autostart <<EOL
xrandr --output HDMI-1 --rotate right
EOL
Hope it works for you as well
