The problem is that Waveshare hasn't kept up with the changes to the Raspberry Pi and the Raspberry Pi OS. There solution uses a program to scrape the image and paste it to the SPI display. The software uses an API called DispmanX which is no longer supported and doesn't work out of the box in Bookworm. Worse still the DispmanX API will never work on a Raspberry Pi 5.I am using Ubuntu right now.Which OS are you running (check in terminal running 'uname -a' to get to know the kernel at least.
Assuming you're on recent Bookworm try adding below to '/boot/firmware/config.txt'Code:
dtoverlay=piscreen,drm,speed=20000000
I haven't tried Ubuntu, so I can't be sure that it contains all the Device Tree overlays available in Raspberry Pi OS. I think it is worth trying aBUGSworstnightmare suggestion. It is the correct solution and should work on Ubuntu. You will need to work out where the config.txt file is on Ubuntu.
