I don't think you're misinterpreting anything, but Josselin is 
correct when they say

In your case, you're using set-xorg-configuration which tries to 
extend your slim-service-type service. Unfortunately, you want to 
define two of them, which causes the extension mechanism to fail 
complaining about the ambiguity.

You should be able to fix this by adding the xorg-configuration 
directly into the slim service that you're defining, something 
like this:

   (cons* (service slim-service-type (slim-configuration
                                      (display ":0")
                                      (vt "vt7")
                                      (xorg-configuration
                                       (xorg-configuration
                                        (modules (list 
                                        xf86-input-libinput
    		                                        xf86-input-evdev
                                                       xf86-input-wacom))
                                        (keyboard-layout 
                                        keyboard-layout)
                                        (server-arguments
                                         ;; disable screen-saver 
                                         timeout
                                         (append (list "-s" "0")
                                                 %default-xorg-server-arguments))
                                        (extra-config (list 
                                        xorg-touchpad
                                                            xorg-monitor))))))
          (service slim-service-type (slim-configuration
                                      (display ":0")
                                      (vt "vt8")
                                      ;; I wasn't sure if you 
                                      wanted the same
                                      ;; xorg-configuration here, 
                                      so I left it out.
                                      ))
          (modify-services %desktop-services
            (delete gdm-service-type)
            (delete (screen-locker-service xlockmore "xlock"))))

I hope that helps,

Carlo
