doc: Restructure the list of desktop services.
* doc/guix.texi (Desktop Services): Use a straight list for the list of service types, rather than hiding them in one growing paragraph of prose. Explain their purpose in general terms beneath it. Change-Id: I2408ccf38dd62323138854cc5aa46051d2a076ac

@ -24618,28 +24618,26 @@ The @code{%desktop-services} variable can be used as the @code{services}
|
|||
field of an @code{operating-system} declaration (@pxref{operating-system
|
||||
Reference, @code{services}}).
|
||||
|
||||
Additionally, the @code{gnome-desktop-service-type},
|
||||
@code{xfce-desktop-service}, @code{mate-desktop-service-type},
|
||||
@code{lxqt-desktop-service-type} and @code{enlightenment-desktop-service-type}
|
||||
procedures can add GNOME, Xfce, MATE and/or Enlightenment to a system. To
|
||||
``add GNOME'' means that system-level services like the backlight adjustment
|
||||
helpers and the power management utilities are added to the system, extending
|
||||
@code{polkit} and @code{dbus} appropriately, allowing GNOME to operate with
|
||||
elevated privileges on a limited number of special-purpose system interfaces.
|
||||
Additionally, adding a service made by @code{gnome-desktop-service-type} adds
|
||||
the GNOME metapackage to the system profile. Likewise, adding the Xfce
|
||||
service not only adds the @code{xfce} metapackage to the system profile, but
|
||||
it also gives the Thunar file manager the ability to open a ``root-mode'' file
|
||||
management window, if the user authenticates using the administrator's
|
||||
password via the standard polkit graphical interface. To ``add MATE'' means
|
||||
that @code{polkit} and @code{dbus} are extended appropriately, allowing MATE
|
||||
to operate with elevated privileges on a limited number of special-purpose
|
||||
system interfaces. Additionally, adding a service of type
|
||||
@code{mate-desktop-service-type} adds the MATE metapackage to the system
|
||||
profile. ``Adding Enlightenment'' means that @code{dbus} is extended
|
||||
appropriately, and several of Enlightenment's binaries are set as setuid,
|
||||
allowing Enlightenment's screen locker and other functionality to work as
|
||||
expected.
|
||||
Additionally, the following procedures add one (or more!) desktop
|
||||
environments to a system.
|
||||
|
||||
@itemize
|
||||
@item @code{gnome-desktop-service-type} adds GNOME,
|
||||
@item @code{plasma-desktop-service-type} adds KDE Plasma,
|
||||
@item @code{enlightenment-desktop-service-type} adds Enlightenment,
|
||||
@item @code{lxqt-desktop-service-type} adds LXQt,
|
||||
@item @code{mate-desktop-service-type} adds MATE, and
|
||||
@item @code{xfce-desktop-service} adds Xfce.
|
||||
@end itemize
|
||||
|
||||
These service types add ``metapackages'' such as @code{gnome} or
|
||||
@code{plasma} to the system profile, but most of them also set up other useful
|
||||
services that mere packages can't do.
|
||||
|
||||
For example, they may elevate privileges on a limited number of
|
||||
special-purpose system interfaces and programs. This allows backlight
|
||||
adjustment helpers, power management utilities, screen lockers, and
|
||||
other integrated functionality to work as expected.
|
||||
|
||||
The desktop environments in Guix use the Xorg display server by
|
||||
default. If you'd like to use the newer display server protocol
