Is fbdev(frame buffer, no GPU) on Linux supported in SDL2.x at all? there are wide use cases for plain framebuffer in the embedded device space and I think SDL1.x supports that, however I could not find documentation or posts to confirm that fbdev is supported in SDL2.x, so far various reading told me there is no fbdev(non-accelerated as there is no GPU) support in SDL2,x, is it true?
My embedded devices also needs this feature,but it is not supported in SDL2. I hope it can be added in later release versions.
You should look at using the directfb backend, you should be able use it with a unaccelerated linux framebuffer
