+ bool "Virtual terminal (needed for framebuffer)" if EMBEDDED

+ default y if !VIOCONS
+ ---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 :-)

+menu "Framebuffer"

+
+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.
+
+ 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.
