[bug#40680] [PATCH] service: sddm: Have sddm-service-type conflict with other display managers.

[Efraim Flashner]

* gnu/services/sddm.scm (sddm-shepherd-service)[shepherd-service]:
Conflict with 'xorg-server.
---

I was looking over the services list with raingloom on IRC and I noticed
that GDM and Slim both provision xorg-server, while SDDM provisions
display-manager. To ensure that they conflict with each other we can
either:

A: Have SDDM conflict with 'xorg-server

B: Have SDDM also provision 'xorg-server

I'm currently using SDDM (in Wayland mode) to launch an X session of
Enlightenment, so I think it's safe enough to say that SDDM can
provision 'xorg-server.
