Thanks for the suggestion! I have no idea about drivers, so it would be great for learning. Pardon my ignorance, but can the gpu render to other display devices as normal?

Yep, it will just result in your driver showing up as another `fb` device. Then, you can configure the kernel fbcon boot parameter to use your display for tty, or launch X configured to use your fb device. This would also let you do fun stuff like run mpv pointed directly at the fb device without running X at all :)

I put my email in my profile, so feel free to message me if you need any pointers.

I see there is an upstream tiny-DRM based kernel driver for ST7735r, which might be compatible with your ST7789, or might require some (hopefully) minimal adjustments: https://elixir.bootlin.com/linux/latest/source/drivers/gpu/d...

haha, it's actually got decent viewing angles as it's ips. I do admit I should have shopped around a bit more though, lots of cheaper options out there.

Good for you. :)
