3361 + ---help---
3362 + If you say Y here, you will get support for terminal devices with
3363 + display and keyboard devices. These are called "virtual" because you
3364 + can run several virtual terminals (also called virtual consoles) on
3365 + one physical terminal. This is rather useful, for example one
3366 + virtual terminal can collect system messages and warnings, another
3367 + one can be used for a text-mode user session, and a third could run
3368 + an X session, all in parallel. Switching between virtual terminals
3369 + is done with certain key combinations, usually Alt-<function key>.
3370 +
3371 + The setterm command ("man setterm") can be used to change the
3372 + properties (such as colors or beeping) of a virtual terminal. The
3373 + man page console_codes(4) ("man console_codes") contains the special
3374 + character sequences that can be used to change those properties
3375 + directly. The fonts used on virtual terminals can be changed with
3376 + the setfont ("man setfont") command and the key bindings are defined
3377 + with the loadkeys ("man loadkeys") command.
3378 +
3379 + You need at least one virtual terminal device in order to make use
3380 + of your keyboard and monitor. Therefore, only people configuring an
3381 + embedded system would want to say N here in order to save some
3382 + memory; the only way to log into such a system is then via a serial
3383 + or network connection.
3384 +
3385 + If unsure, say Y, or else you won't be able to do much with your new
3386 + shiny Linux system :-)

3393 + bool "Support for frame buffer devices"
3394 + depends on VT
3395 + ---help---
3396 + The frame buffer device provides an abstraction for the graphics
3397 + hardware. It represents the frame buffer of some video hardware and
3398 + allows application software to access the graphics hardware through
3399 + a well-defined interface, so the software doesn't need to know
3400 + anything about the low-level (hardware register) stuff.
3401 +
3402 + Frame buffer devices work identically across the different
3403 + architectures supported by Linux and make the implementation of
3404 + application programs easier and more portable; at this point, an X
3405 + server exists which uses the frame buffer device exclusively.
3406 + On several non-X86 architectures, the frame buffer device is the
3407 + only way to use the graphics hardware.
3408 +
3409 + The device is accessed through special device nodes, usually located
3410 + in the /dev directory, i.e. /dev/fb*.
3411 +
3412 + You need an utility program called fbset to make full use of frame
3413 + buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
3414 + and the Framebuffer-HOWTO at
3415 + <http://www.tahallah.demon.co.uk/programming/prog.html> for more
3416 + information.
3417 +
3418 + Say Y here and to the driver for your graphics board below if you
3419 + are compiling a kernel for a non-x86 architecture.
3420 +
3421 + If you are compiling for the x86 architecture, you can say Y if you
3422 + want to play with it, but it is not essential. Please note that
3423 + running graphical applications that directly touch the hardware
3424 + (e.g. an accelerated X server) and that are not frame buffer
3425 + device-aware may cause unexpected results. If unsure, say N.

3865 + If you say Y here, you will get support for terminal devices with
3866 + display and keyboard devices. These are called "virtual" because you
3867 + can run several virtual terminals (also called virtual consoles) on
3868 + one physical terminal. This is rather useful, for example one
3869 + virtual terminal can collect system messages and warnings, another
3870 + one can be used for a text-mode user session, and a third could run
3871 + an X session, all in parallel. Switching between virtual terminals
3872 + is done with certain key combinations, usually Alt-<function key>.
3873 +
3874 + The setterm command ("man setterm") can be used to change the
3875 + properties (such as colors or beeping) of a virtual terminal. The
3876 + man page console_codes(4) ("man console_codes") contains the special
3877 + character sequences that can be used to change those properties
3878 + directly. The fonts used on virtual terminals can be changed with
3879 + the setfont ("man setfont") command and the key bindings are defined
3880 + with the loadkeys ("man loadkeys") command.
3881 +
3882 + You need at least one virtual terminal device in order to make use
3883 + of your keyboard and monitor. Therefore, only people configuring an
3884 + embedded system would want to say N here in order to save some
3885 + memory; the only way to log into such a system is then via a serial
3886 + or network connection.

3889 + shiny Linux system :-)

3896 + bool "Support for frame buffer devices"
3897 + depends on VT
3898 + ---help---
3899 + The frame buffer device provides an abstraction for the graphics
3900 + hardware. It represents the frame buffer of some video hardware and
3901 + allows application software to access the graphics hardware through
3902 + a well-defined interface, so the software doesn't need to know
3903 + anything about the low-level (hardware register) stuff.
3904 +
3905 + Frame buffer devices work identically across the different
3906 + architectures supported by Linux and make the implementation of
3907 + application programs easier and more portable; at this point, an X
3908 + server exists which uses the frame buffer device exclusively.
3909 + On several non-X86 architectures, the frame buffer device is the
3910 + only way to use the graphics hardware.
3911 +
3912 + The device is accessed through special device nodes, usually located
3913 + in the /dev directory, i.e. /dev/fb*.
3914 +
3915 + You need an utility program called fbset to make full use of frame
3916 + buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
3917 + and the Framebuffer-HOWTO at
3918 + <http://www.tahallah.demon.co.uk/programming/prog.html> for more
3919 + information.
3920 +

3922 + are compiling a kernel for a non-x86 architecture.
3923 +
3924 + If you are compiling for the x86 architecture, you can say Y if you
3925 + want to play with it, but it is not essential. Please note that
3926 + running graphical applications that directly touch the hardware
3927 + (e.g. an accelerated X server) and that are not frame buffer
3928 + device-aware may cause unexpected results. If unsure, say N.

4372 + man page console_codes(4) ("man console_codes") contains the special
4373 + character sequences that can be used to change those properties
4374 + directly. The fonts used on virtual terminals can be changed with
4375 + the setfont ("man setfont") command and the key bindings are defined
4376 + with the loadkeys ("man loadkeys") command.

4378 + You need at least one virtual terminal device in order to make use
4379 + of your keyboard and monitor. Therefore, only people configuring an
4380 + embedded system would want to say N here in order to save some
4381 + memory; the only way to log into such a system is then via a serial
4382 + or network connection.
4383 +

4385 + shiny Linux system :-)

4392 + bool "Support for frame buffer devices"
4393 + depends on VT
4394 + ---help---
4395 + The frame buffer device provides an abstraction for the graphics
4396 + hardware. It represents the frame buffer of some video hardware and
4397 + allows application software to access the graphics hardware through
4398 + a well-defined interface, so the software doesn't need to know
4399 + anything about the low-level (hardware register) stuff.
4400 +
4401 + Frame buffer devices work identically across the different
4402 + architectures supported by Linux and make the implementation of
4403 + application programs easier and more portable; at this point, an X
4404 + server exists which uses the frame buffer device exclusively.
4405 + On several non-X86 architectures, the frame buffer device is the
4406 + only way to use the graphics hardware.
4407 +
4408 + The device is accessed through special device nodes, usually located
4409 + in the /dev directory, i.e. /dev/fb*.
4410 +
4411 + You need an utility program called fbset to make full use of frame
4412 + buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
4413 + and the Framebuffer-HOWTO at
4414 + <http://www.tahallah.demon.co.uk/programming/prog.html> for more
4415 + information.
4416 +
4417 + Say Y here and to the driver for your graphics board below if you
4418 + are compiling a kernel for a non-x86 architecture.
4419 +
4420 + If you are compiling for the x86 architecture, you can say Y if you
4421 + want to play with it, but it is not essential. Please note that
4422 + running graphical applications that directly touch the hardware
4423 + (e.g. an accelerated X server) and that are not frame buffer
4424 + device-aware may cause unexpected results. If unsure, say N.
