++ ---help---
++ If you say Y here, you will get support for terminal devices with
++ display and keyboard devices. These are called "virtual" because you
++ can run several virtual terminals (also called virtual consoles) on
++ one physical terminal. This is rather useful, for example one
++ virtual terminal can collect system messages and warnings, another
++ one can be used for a text-mode user session, and a third could run
++ an X session, all in parallel. Switching between virtual terminals
++ is done with certain key combinations, usually Alt-<function key>.
++
++ The setterm command ("man setterm") can be used to change the
++ properties (such as colors or beeping) of a virtual terminal. The
++ man page console_codes(4) ("man console_codes") contains the special
++ character sequences that can be used to change those properties
++ directly. The fonts used on virtual terminals can be changed with
++ the setfont ("man setfont") command and the key bindings are defined
++ with the loadkeys ("man loadkeys") command.
++
++ You need at least one virtual terminal device in order to make use
++ of your keyboard and monitor. Therefore, only people configuring an
++ embedded system would want to say N here in order to save some
++ memory; the only way to log into such a system is then via a serial
++ or network connection.

++ If unsure, say Y, or else you won't be able to do much with your new
++ shiny Linux system :-)

++config FB
++ bool "Support for frame buffer devices"
++ depends on VT
++ ---help---
++ The frame buffer device provides an abstraction for the graphics
++ hardware. It represents the frame buffer of some video hardware and
++ allows application software to access the graphics hardware through
++ a well-defined interface, so the software doesn't need to know
++ anything about the low-level (hardware register) stuff.
++
++ Frame buffer devices work identically across the different
++ architectures supported by Linux and make the implementation of
++ application programs easier and more portable; at this point, an X
++ server exists which uses the frame buffer device exclusively.
++ On several non-X86 architectures, the frame buffer device is the
++ only way to use the graphics hardware.
++
++ The device is accessed through special device nodes, usually located
++ in the /dev directory, i.e. /dev/fb*.
++
++ You need an utility program called fbset to make full use of frame
++ buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
++ and the Framebuffer-HOWTO at
++ <http://www.tahallah.demon.co.uk/programming/prog.html> for more
++ information.
