services: xorg: Define an <xorg-configuration> record type.
* gnu/services/xorg.scm (<xorg-configuration>): New record type. (xorg-configuration-file): Remove. (xorg-wrapper): Remove #:modules, #:configuration-file, and #:xorg-server; add optional 'config' parameter instead. Adjust accordingly. (xorg-start-command): Likewise. * doc/guix.texi (X Window): Document 'xorg-configuration'. Update 'xorg-start-command' documentation. Remove 'xorg-configuration-file' documentation.

+@cindex Xorg, configuration
+@deftp {Data Type} xorg-configuration
+This data type represents the configuration of the Xorg graphical display
+server. Note that there is not Xorg service; instead, the X server is started
+by a ``display manager'' such as GDM, SDDM, and SLiM. Thus, the configuration
+of these display managers aggregates an @code{xorg-configuration} record.
-Usually the X server is started by a login manager.
-@end deffn
+@table @asis
+@item @code{modules} (default: @code{%default-xorg-modules})
+This is a list of @dfn{module packages} loaded by the Xorg
+server---e.g., @code{xf86-video-vesa}, @code{xf86-input-keyboard}, and so on.
-@cindex @code{-listen tcp}, for X11.
-This procedure is useful to override command line options for the X server,
-such as having it listen to over TCP:
+@item @code{fonts} (default: @code{%default-xorg-fonts})
+This is a list of font directories to add to the server's @dfn{font path}.

-@cindex keymap

-This procedure is especially useful to configure a different keyboard layout

-@end example

-The @code{MatchIsKeyboard} line specifies that we only apply the configuration
-to keyboards. Without this line, other devices such as touchpad may not work
-correctly because they will be attached to the wrong driver. In this example,
-the user typically used @code{setxkbmap fr bepo} to set their favorite keymap
-once logged in. The first argument corresponds to the layout, while the second
-argument corresponds to the variant. The @code{xkb_variant} line can be omitted
-to select the default variant.
