0012 Say Y here if you have any input device (mouse, keyboard, tablet,
0013 joystick, steering wheel ...) connected to your system and want
0014 it to be available to applications. This includes standard PS/2
0015 keyboard and mouse.
0016
0017 Say N here if you have a headless (no monitor, no keyboard) system.

0159 want all events (keypresses, mouse movements), to be output to
0160 the system log. While this is useful for debugging, it's also
0161 a security threat - your keypresses include your passwords, of
