Bookworm - SPI display devices

## SPI (Serial Peripheral Interface) display devices There are a plethora of small displays that hasn't a standard HDMI interface but a SPI interface. The SPI display devices have their own "display drivers". SPI is an electrical interface. ## Bookworm Changes When the Raspberry Pi OS, Bookworm was released, one of the large changes was the change of display server from the old and sturdy X.org aka X/X.11 to Wayland. This has caused a lot of graphic drivers to cease working as they are not compatible with Wayland. ## Recommendation Contact the seller and ask for a Wayland compatible driver.
