Using this Pi image on my Pi 4B

Comment out these 2 lines in /boot/firmware/config.txt (Add # to the beginning of both lines)

Open the file using command sudo nano /boot/firmware/config.txt

#dtoverlay=vc4-kms-v3d #max_framebuffers=2

And add this at the bottom of the file after [all]

dtoverlay=ft5406 dtoverlay=pi3-disable-bt then Save & Edit CTRL+X and Y then sudo reboot

Once it comes back up, touch will work (or should work, if the screen is connected correctly).

If you are still experiencing issues ensure that all of the little ribbon cables on the back of the display are seated correctly too.
