kbd - Keyboard input driver
kbd is an Xorg input driver for keyboards. The driver supports the
standard OS-provided keyboard interface, but these are currently only
available to this driver module for Linux, BSD, and Solaris. This
driver is the replacement for the built-in keyboard driver formerly
included in Xorg.
The kbd driver functions as a keyboard input device, and may be used as
the X server's core keyboard.
Please refer to xorg.conf(5) for general configuration details and for
options that can be used with all input drivers. This section only
covers configuration details specific to this driver.

Option "XLeds" "ledlist"

most platforms, but "pc98" for the Japanese PC-98 platforms.
Option "XkbLayout" "layoutname"
specifies the XKB keyboard layout name. This is usually the
country or language type of the keyboard. Default: "us" for
most platforms, but "nec/jp" for the Japanese PC-98 platforms.
Option "XkbVariant" "variants"
specifies the XKB keyboard variant components. These can be
used to enhance the keyboard layout details. Default: not set.
Option "XkbOptions" "options"
specifies the XKB keyboard option components. These can be used
to enhance the keyboard behaviour. Default: not set.
Some other XKB-related options are available, but they are incompatible
with the ones listed above and are not recommended, so they are not
The following xorg.conf fragment ensures that user will be able to
switch between us and sk layouts by pressing the "menu" key.
The XkbVariant option defines which variants of the two layouts should
be used. In case of the us layout its default variant is used. In case
of the sk layout its qwerty variant is used.
