1019 The frame buffer device provides an abstraction for the graphics
1020 hardware. It represents the frame buffer of some video hardware and
1021 allows application software to access the graphics hardware through
1022 a well-defined interface, so the software doesn't need to know
1023 anything about the low-level (hardware register) stuff.
1025 Frame buffer devices work identically across the different
1026 architectures supported by Linux and make the implementation of
1027 application programs easier and more portable; at this point, an X
1028 server exists which uses the frame buffer device exclusively.
1029 On several non-X86 architectures, the frame buffer device is the
1030 only way to use the graphics hardware.
1032 The device is accessed through special device nodes, usually located
1033 in the /dev directory, i.e. /dev/fb*.
1035 You need an utility program called fbset to make full use of frame
1036 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
1037 and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>

1041 are compiling a kernel for a non-x86 architecture.
1043 If you are compiling for the x86 architecture, you can say Y if you
1044 want to play with it, but it is not essential. Please note that
1045 running graphical applications that directly touch the hardware
1046 (e.g. an accelerated X server) and that are not frame buffer
1047 device-aware may cause unexpected results. If unsure, say N.
