Installed using LCD35-Show lite, display are fine but touch screen does not seem to work at all, any howtos for troubleshooting?

Same with the LCD 3.2 (b) v4. Installed latest version of Raspian desktop on my 2w and only the screen display works after installing drivers, no touch.

Same here with LCD 3.5 B v2. Latest Raspbian Desktop on Pi400.

Same with LCD 10.1. Worked for a while but every now and then it isn't working.

Same here...

Has anyone been able to make the touch work? I bought the screen to use it with as OctoDash but is worthless without the touch functionality.

got it running on Pi 4B with kernel 6.1 on bullseye and bookworm (Raspberry PI OS 64-bit version) following [waveshare wiki instructions] (https://www.waveshare.com/wiki/3.5inch_RPi_LCD_(C)#Install_the_touch_driver)
(example for C version)

also assuming x-org is used (and not wayland on bookworm)

following must be run with root privilege: 

./LCD35C-show

# now
sudo  ./LCD35C-show

then updating (or creating) /usr/share/X11/xorg.conf.d/99-fbdev.conf as mentioned here:

  # output to LCD screen
  Option "fbdev" "/dev/fb1"

  # or replace with this to output to HDMI instead
  Option "fbdev" "/dev/fb0"
