The Waveshare 4.3" DSI touch screen on my Voron 2.4 lost all touch input sometime yesterday, after upgrading all the OS packages and Mainsail to 2.5. I doubt it's a Mainsail issue but was hoping maybe some folks here could give some pointers on how to troubleshoot it. I found a thread on the /r/klippers SubReddit where several others also had this bite them in the past few days. I'm running the 64 bit OS on a Pi 4B. I assume something in one of the Raspian OS updates has gone haywire. Any help is appreciated.

I'm having the same issue with my BTT Pi TFT50, rest of my setup is the same. The screen's touch functionality was verified as still working under a different OS, so it's specific to recently updated software on my Pi. There's an active issue concerning this on the Klipperscreen github, although I do not know for a fact it's related to Klipperscreen. https://github.com/jordanruthe/KlipperScreen/issues/928

Following the "Touch not working on Debian Bullseye" steps on the Klipperscreen website fixed this issue for me. Dumb of me- I saw that section before but didn't try because it was working under Bullseye previously.

Could not find the option in raspi-config, so I manually edited config.txt
