-+ If you say Y here, you will get support for terminal devices with

-+ 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.

-+ 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.
-+
-+ Say Y here and to the driver for your graphics board below if you
-+ are compiling a kernel for a non-x86 architecture.
-+
-+ If you are compiling for the x86 architecture, you can say Y if you
-+ want to play with it, but it is not essential. Please note that
-+ running graphical applications that directly touch the hardware
-+ (e.g. an accelerated X server) and that are not frame buffer
-+ device-aware may cause unexpected results. If unsure, say N.

-+ The device is accessed through special device nodes, usually located
