default y
|
help
|
Say Y here if you have any input device (mouse, keyboard, tablet,
|
joystick, steering wheel ...) connected to your system and want
|
it to be available to applications. This includes standard PS/2
|
keyboard and mouse.
|
|
Say N here if you have a headless (no monitor, no keyboard) system.

tristate "Support for memoryless force-feedback devices"
|
help
|
Say Y here if you have memoryless force-feedback input device
|
such as Logitech WingMan Force 3D, ThrustMaster FireStorm Dual
|
Power 2, or similar. You will also need to enable hardware-specific
|
driver.
|
|
If unsure, say N.

config INPUT_POLLDEV
|
tristate "Polled input device skeleton"
|
help
|
Say Y here if you are using a driver for an input
|
device that periodically polls hardware state. This
|
option is only useful for out-of-tree drivers since
|
in-tree drivers select it automatically.
|
|
If unsure, say N.

Say Y here if you are using a driver for an input
|
device that uses sparse keymap. This option is only

useful for out-of-tree drivers since in-tree drivers
|
select it automatically.

tristate "Mouse interface"
|
help
|
Say Y here if you want your mouse to be accessible as char devices
|
13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
|
emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
|
programs (including SVGAlib, GPM and X) will be able to use your
|
mouse.
|
|
If unsure, say Y.

help

Say Y here if you want your mouse also be accessible as char device
|
10:1 - /dev/psaux. The data available through /dev/psaux is exactly
|
the same as the data from /dev/input/mice.
|
|
If unsure, say Y.

|
help
|
If you're using a digitizer, or a graphic tablet, and want to use
|
it as a mouse then the mousedev driver needs to know the X window
|
screen resolution you are using to correctly scale the data. If
|
you're not using a digitizer, this value is ignored.

Say Y here if you want your joystick or gamepad to be

accessible as char device 13:0+ - /dev/input/jsX device.

If unsure, say Y.

config INPUT_EVBUG
|
tristate "Event debugging"
|
help
|
Say Y here if you have a problem with the input subsystem and
|
want all events (keypresses, mouse movements), to be output to
|
the system log. While this is useful for debugging, it's also
|
a security threat - your keypresses include your passwords, of
|
course.
|
|
If unsure, say N.

config INPUT_APMPOWER
|
tristate "Input Power Event -> APM Bridge" if EXPERT
|
depends on INPUT && APM_EMULATION
|
help
|
Say Y here if you want suspend key events to trigger a user
|
requested suspend through APM. This is useful on embedded
|
systems where such behaviour is desired without userspace
|
interaction. If unsure, say N.
