You need to remove the default slim service and add your own.  You can
use 'service-kind' procedure to check if the service is the one you
need.

See <http://lists.gnu.org/archive/html/help-guix/2016-01/msg00064.html>
and surrounding messages.

So it would look something like this :

  (cons (slim-service ...)  ; your service
        (remove (lambda (service)
                  (eq? (service-kind service)
                       slim-service-type))
                %desktop-services))

Note that 'remove' is from (srfi srfi-1), 'service-kind' is from (gnu
services), 'slim-service-type' is from (gnu services xorg), so you need
to use all these modules in your config file.
