This config not works. It causes error on building xserver:
'ERROR: In procedure scm-error:
In procedure for-each: Wrong type argument: "Section \"InputClass\"\n        Identifier \"touchpad\"\n        Driver \"libinput\"\n        MatchIsTouchpad \"on\"\n        Option \"Tapping\" \"on\"\nEndSection"'

I've found with `info guix` this:

 Let’s say you want your system to use the Turkish keyboard layout
throughout your system—bootloader, console, and Xorg.  Here’s what your
system configuration would look like:

     ;; Using the Turkish layout for the bootloader, the console,
     ;; and for Xorg.

     (operating-system
       ;; ...
       (keyboard-layout (keyboard-layout "tr"))  ;for the console
       (bootloader (bootloader-configuration
                     (bootloader grub-efi-bootloader)
                     (target "/boot/efi")
                     (keyboard-layout keyboard-layout))) ;for GRUB
       (services (modify-services %desktop-services
                   (slim-service-type config =>
                     (slim-configuration
                       (inherit config)
                       (xorg-configuration
                         (xorg-configuration             ;for Xorg
                           (keyboard-layout keyboard-layout))))))))

   In the example above, for GRUB and for Xorg, we just refer to the
‘keyboard-layout’ field defined above, but we could just as well refer
to a different layout.


But word 'touchpad' absents in `ingo guix`. I do not know what to do.
