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

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