  924. The frame buffer device provides an abstraction for the graphics
  925. hardware. It represents the frame buffer of some video hardware and
  926. allows application software to access the graphics hardware through
  927. a well-defined interface, so the software doesn't need to know
  928. anything about the low-level (hardware register) stuff.
  929. Frame buffer devices work identically across the different
  930. architectures supported by Linux and make the implementation of
  931. application programs easier and more portable; at this point, an X
  932. server exists which uses the frame buffer device exclusively.
  933. On several non-X86 architectures, the frame buffer device is the
  934. only way to use the graphics hardware.
  935. The device is accessed through special device nodes, usually located
  936. in the /dev directory, i.e. /dev/fb*.
  937. You need an utility program called fbset to make full use of frame
  938. buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
  939. and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>

  942. are compiling a kernel for a non-x86 architecture.
  943. If you are compiling for the x86 architecture, you can say Y if you
  944. want to play with it, but it is not essential. Please note that
  945. running graphical applications that directly touch the hardware
  946. (e.g. an accelerated X server) and that are not frame buffer
  947. device-aware may cause unexpected results. If unsure, say N.
