Dear Forum,

I have an RaspberryPi setup with two (1.8") 160x128 TFT displays which appear as /dev/fb1 and /dev/fb2. I am using SDL via pygame for development.

SDL_FBDEV works for each display separately, but I would like to be able to access both simultaneously from the same application.

Is it possible to somehow merge the two framebuffers into a single object which would appear to SDL/pygame as a single 320x128 (or 160x256) display?

I would like to avoid start X if possible.

Thanks,
