To complement what Marius wrote, note that you don’t have to use
‘%desktop-services’ as-is to get X running.  You can remove services you
don’t want from ‘%desktop-services’ as shown at
<https://www.gnu.org/software/guix/manual/html_node/Using-the-Configuration-System.html#System-Services>
(search for “remove”), or you can build your own service list.

In the latter case, you’ll want at least ‘slim-service’ or
‘sddm-service’ for the graphical login manager.  See
<https://www.gnu.org/software/guix/manual/html_node/X-Window.html> and
<https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/services/desktop.scm#n749>.

If you don’t want a graphical login manager, the solution would be to
install ‘xinit’ (which provides the ‘startx’ command) rather than make
Xorg setuid-root.  However, people reported in the past that there were
problems with ‘xinit’, though I forgot what it was.

HTH,
Ludo’.
