Troubleshooting • Re: Waveshare 4.3" Capacitive works, but touch doesn't

For anyone trying to get this touchscreen working on a Raspberry Pi 3B+ do the following.

Look for this line on the config.txt

# Enable DRM VC4 V3D driver
dtoverlay=vc4-kms-v3d
max_framebuffers=2

and comment it out.

Add the following lines to the end of the config.txt

#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

#Additional overlays and parameters are documented /boot/overlays/README#

#Enable audio (loads snd_bcm2835 )
dtparam=audio=on

[pi4]
#Enable DRM VC4 V3D driver on top of dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

and your touchscreen should now be active.
