You don't have to repeat the use-modules form, it can be used like this:
(use-modules (gnu)
              (gnu system nss)
              (gnu packages tryton)
              (gnu packages databases)
              (gnu packages xorg))

I'm actually surprised the other way works, but noticed it appears for 
"Globally-Visible Packages" at:
https://www.gnu.org/software/guix/manual/html_node/Using-the-Configuration-System.html

Why do you use one level of indirection for no gain? This can go into 
services, directly.

That modify-services looks very suspicious. Why the nested cons*?
modify-services should be fed with one list of services, followed by 
(type variable => body) clauses, like in:


(modify-services %desktop-services
   (mingetty-service-type config =>
     (mingetty-configuration
       (inherit config)
       (motd (plain-file "motd" "Howdy FOSDEM!"))))
   (upower-service-type config =>
     (upower-configuration
       (inherit config)
       (ignore-lid? #true)
       (percentage-critical 5.))))


modify-services %desktop-services
  (udev-service-type config =>
    (udev-configuration (inherit config)
     (rules (append (udev-configuration-rules config)
                    (list %example-udev-rule))))))


Aside of that, I wonder if you have to put the xorg server into either 
global packages, or install it for root.

(crypt " " "ab") looks suspicious to me, but I haven't read up on how it 
should be used.
