It is true I forgot to add some details about what I'm trying to do. I am trying to make a non-accelerated windowing system as a personnal project which is the reason why I am not using Xlib nor libdrm. > Is it intended as a programming exercise, or to solve a particular local > problem, or is it being developed for public release and intended to be > portable to other systems? > > What hardware are you developing this on? I am not trying to make this portable, just working on my machine which is a 64-bit amd CPU. I was able to get efifb configured after disabling amdgpu and set the display mode to dumbfb but the problem is when switching ttys the framebuffer that was received through mmap is still displayed.
