11 The frame buffer device provides an abstraction for the graphics
12 hardware. It represents the frame buffer of some video hardware and
13 allows application software to access the graphics hardware through
14 a well-defined interface, so the software doesn't need to know
15 anything about the low-level (hardware register) stuff.
17 Frame buffer devices work identically across the different
18 architectures supported by Linux and make the implementation of
19 application programs easier and more portable; at this point, an X
20 server exists which uses the frame buffer device exclusively.
21 On several non-X86 architectures, the frame buffer device is the
22 only way to use the graphics hardware.
24 The device is accessed through special device nodes, usually located
25 in the /dev directory, i.e. /dev/fb*.
27 You need an utility program called fbset to make full use of frame
28 buffer devices. Please read <file:Documentation/fb/framebuffer.rst>
29 and the Framebuffer-HOWTO at
30 <http://www.munted.org.uk/programming/Framebuffer-HOWTO-1.3.html> for more
31 information.
33 This enables support for native frame buffer device (fbdev) drivers.
35 The DRM subsystem provides support for emulated frame buffer devices
36 on top of KMS drivers, but this option allows legacy fbdev drivers to
37 be enabled as well.
39 Say Y here and to the driver for your graphics board below if you
40 are compiling a kernel for a non-x86 architecture.
42 If you are compiling for the x86 architecture, you can say Y if you
43 want to play with it, but it is not essential. Please note that
44 running graphical applications that directly touch the hardware
45 (e.g. an accelerated X server) and that are not frame buffer
46 device-aware may cause unexpected results. If unsure, say N.

786 per video mode. Since the GTF allows nondiscrete timings
787 (nondiscrete being a range of values as opposed to discrete being a
788 set of values), you'll be able to use any combination of horizontal
789 and vertical resolutions, and vertical refresh rates without having
790 to specify your own timing parameters. This is especially useful
