I'm having the weirdest issue with KlipperScreen.
I decided to do a fresh install on the RPi 2B that runs my Ender 3V2, since it was quite long in the tooth. At first I went with MainsailOS, but that proved to be a mistake. It was horrendously slow. But at least KlipperScreen worked as intended.
So I switched to Raspberry Pi OS Lite, and used KIAUH to install Klipper and everything else. Everything works perfectly fine, except for the KlipperScreen output.
I have tried many different configuration tweaks in config.txt and cmdline.txt,to no avail. Sometimes the HDMI output is completely disabled, but still KlipperScreen won't show on the DSI display. The weirdest part is that the touch input is detected and correctly applied to the buttons shown in the monitor.
BTW, the display is a 5'' DSI 800x480 IPS touchscreen.
There are absolutely no error messages in the logs, which I guess is to be expected, since it's technically working, just not displaying where I need it to.
I would greatly appreciate any tips on how to resolve this. I've been fiddling with this for several hours, and I have run out of ideas.
