979 The frame buffer device provides an abstraction for the graphics
980 hardware. It represents the frame buffer of some video hardware and
981 allows application software to access the graphics hardware through
982 a well-defined interface, so the software doesn't need to know
983 anything about the low-level (hardware register) stuff.
985 Frame buffer devices work identically across the different
986 architectures supported by Linux and make the implementation of
987 application programs easier and more portable; at this point, an X
988 server exists which uses the frame buffer device exclusively.
989 On several non-X86 architectures, the frame buffer device is the
990 only way to use the graphics hardware.
992 The device is accessed through special device nodes, usually located
993 in the /dev directory, i.e. /dev/fb*.
995 You need an utility program called fbset to make full use of frame
996 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
