I have been building on a Pi with a 7 inch touch screen

I started out looking for lightweight X-Windows solutions, for the LLM and me to use. Cutting a long and frustrating story short I settled on SDL2 Rust wrapper

But what a PITA X-Windows is (e.g. need Wayland for some things, but does not work well for others), and my goal is an appliance, not an app.

So in a moment of insight I spent an afternoon getting SDL2 to draw on the Framebuffer and dispensed with X entirely

I highly recommend this approach. Life is so much easier without X-Windows
