1033 The frame buffer device provides an abstraction for the graphics
1034 hardware. It represents the frame buffer of some video hardware and
1035 allows application software to access the graphics hardware through
1036 a well-defined interface, so the software doesn't need to know
1037 anything about the low-level (hardware register) stuff.
1039 Frame buffer devices work identically across the different
1040 architectures supported by Linux and make the implementation of
1041 application programs easier and more portable; at this point, an X
1042 server exists which uses the frame buffer device exclusively.
1043 On several non-X86 architectures, the frame buffer device is the
1044 only way to use the graphics hardware.
1046 The device is accessed through special device nodes, usually located
1047 in the /dev directory, i.e. /dev/fb*.
1049 You need an utility program called fbset to make full use of frame
1050 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
1051 and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>

1055 are compiling a kernel for a non-x86 architecture.

1059 running graphical applications that directly touch the hardware
1060 (e.g. an accelerated X server) and that are not frame buffer
1061 device-aware may cause unexpected results. If unsure, say N.
