1096 The frame buffer device provides an abstraction for the graphics
1097 hardware. It represents the frame buffer of some video hardware and
1098 allows application software to access the graphics hardware through
1099 a well-defined interface, so the software doesn't need to know
1100 anything about the low-level (hardware register) stuff.
1102 Frame buffer devices work identically across the different
1103 architectures supported by Linux and make the implementation of
1104 application programs easier and more portable; at this point, an X
1105 server exists which uses the frame buffer device exclusively.
1106 On several non-X86 architectures, the frame buffer device is the
1107 only way to use the graphics hardware.
1109 The device is accessed through special device nodes, usually located
1110 in the /dev directory, i.e. /dev/fb*.
1112 You need an utility program called fbset to make full use of frame
1113 buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
1114 and the Framebuffer-HOWTO at <http://www.tldp.org/docs.html#howto>

1122 running graphical applications that directly touch the hardware
