El módulo (gnu services desktop) proporciona servicios que son útiles
habitualmente en el contexto de una configuración de “escritorio”—es
decir, en una máquina que ejecute un servidor gráfico, posiblemente con
interfaces gráficas, etcétera. También define servicios que proporcionan
entornos de escritorio específicos como GNOME, Xfce o MATE.
Para simplificar las cosas, el módulo define una variable que contiene el conjunto de servicios que las usuarias esperarían de manera habitual junto a un entorno gráfico y de red:
Es una lista de servicios que se construye en base a %base-services y
añade o ajusta servicios para una configuración de “escritorio” típica.
In particular, it adds a graphical login manager (see gdm-service-type), screen lockers, a network management tool
(see network-manager-service-type) with
modem support (see modem-manager-service-type), energy and color management services,
the elogind login and seat manager, the Polkit privilege service, the
GeoClue location service, the AccountsService daemon that allows authorized
users change system passwords, a NTP client (see Servicios de red)
and the Avahi daemon.
La variable %desktop-services puede usarse como el campo
services de una declaración operating-system
(see services).
Additionally, the following procedures add one (or more!) desktop environments to a system.
gnome-desktop-service-type adds GNOME,
plasma-desktop-service-type adds KDE Plasma,
enlightenment-desktop-service-type adds Enlightenment,
lxqt-desktop-service-type adds LXQt,
mate-desktop-service-type adds MATE, and
xfce-desktop-service adds Xfce.
These service types add “metapackages” such as gnome or
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 called Wayland, you need
to enable Wayland support in GDM (see wayland-gdm). Another solution is
to use the sddm-service instead of GDM as the graphical login
manager. You should then select the “GNOME (Wayland)” session in SDDM.
Alternatively you can also try starting GNOME on Wayland manually from a TTY
with the command “XDG_SESSION_TYPE=wayland exec dbus-run-session
gnome-session“. Currently only GNOME has support for Wayland.
Es el tipo del servicio que añade el entorno de escritorio
GNOME. Su valor es un objeto
gnome-desktop-configuration (véase a continuación).

Configuration record for the GNOME desktop environment. Available
gnome-desktop-configuration fields are:
core-services (type: list-of-packages)A list of packages that the GNOME Shell and applications may rely on.
shell (type: list-of-packages)A list of packages that constitute the GNOME Shell, without applications.
utilities (type: list-of-packages)A list of packages that serve as applications to use on top of the GNOME Shell.
gnome (type: maybe-package)This field used to be the only configuration point and specified a GNOME meta-package to install system-wide. Since the meta-package itself provides neither sources nor the actual packages and is only used to propagate them, this field is deprecated.
extra-packages (type: list-of-packages)A list of GNOME-adjacent packages to also include. This field is intended for users to add their own packages to their GNOME experience. Note, that it already includes some packages that are considered essential by some (most?) GNOME users.
udev-ignorelist (default: ()) (type: list-of-strings)A list of regular expressions denoting udev rules or hardware file names provided by any package that should not be installed. By default, every udev rule and hardware file specified by any package referenced in the other fields are installed.
polkit-ignorelist (default: ()) (type: list-of-strings)A list of regular expressions denoting polkit rules provided by any package that should not be installed. By default, every polkit rule added by any package referenced in the other fields are installed.
This is the type of the service that adds the

This service adds the plasma package to the system profile.

Note that xfce4-panel and its plugin packages should be installed in
the same profile to ensure compatibility. When using this service, you
should add extra plugins (xfce4-whiskermenu-plugin,
xfce4-weather-plugin, etc.) to the packages field of your
operating-system.

Devuelve un servicio que añade el paquete enlightenment al perfil del
sistema, y extiende dbus con acciones de efl.
enlightenment (predeterminado: enlightenment)El paquete enlightenment usado.
Debido a que los servicios de escritorio GNOME, Xfce y MATE incorporan
tantos paquetes, la variable %desktop-services no incluye ninguno de
manera predeterminada. Para añadir GNOME, Xfce o MATE, simplemente use
cons junto a %desktop-services en el campo services de
su declaración operating-system:
(use-modules (gnu)) (use-service-modules desktop) (operating-system ... ;; cons* añade elementos a la lista proporcionada en el último ;; parámetro. (services (cons* (service gnome-desktop-service-type) (service xfce-desktop-service) %desktop-services)) ...)

management daemon that provides user interfaces with notifications and ways
to mount/unmount disks. Programs that talk to UDisks include the
udisksctl command, part of UDisks, and GNOME Disks. Note that
Udisks relies on the mount command, so it will only be able to use
the file-system utilities installed in the system profile. For example if

supports many recent scanners.
This package includes support for all scanners that

which follows the same policy as to BR/EDR that publishes the identity
address when discoverable, and Network Privacy Mode for scanning

seatd is a minimal seat management daemon.
Seat management takes care of mediating access to shared devices (graphics, input), without requiring the applications needing access to be root.
(append
(list
;; make sure seatd is running
(service seatd-service-type))
;; normally one would want %base-services
%base-services)
seatd operates over a UNIX domain socket, with libseat
providing the client side of the protocol. Applications that acquire access
to the shared resources via seatd (e.g. sway) need to be able
to talk to this socket. This can be achieved by adding the user they run
under to the group owning seatd’s socket (usually “seat”), like so:
(user-account
(name "alice")
(group "users")
(supplementary-groups '("wheel" ; allow use of sudo, etc.
"seat" ; seat management
"audio" ; sound card
"video" ; video devices such as webcams
"cdrom")) ; the good ol' CD-ROM
