machine running a graphical display server, possibly with graphical user
interfaces, etc.
To simplify things, the module defines a variable containing the set of
services that users typically expect on a machine with a graphical
environment and networking:
@defvr {Scheme Variable} %desktop-services
This is a list of services that builds upon @var{%base-services} and
adds or adjust services for a typical ``desktop'' setup.
In particular, it adds a graphical login manager (@pxref{X Window,
@code{slim-service}}), a network management tool (@pxref{Networking
Services, @code{wicd-service}}), energy and color management services,
an NTP client and an SSH server (@pxref{Networking Services}), the Avahi
daemon, and has the name service switch service configured to be able to
use @code{nss-mdns} (@pxref{Name Service Switch, mDNS}).
@end defvr
The @var{%desktop-services} variable can be used as the @code{services}
field of an @code{operating-system} declaration (@pxref{operating-system
Reference, @code{services}}).
The actual service definitions provided by @code{(gnu services desktop)}
are described below.
@deffn {Monadic Procedure} dbus-service @var{services} @
[#:dbus @var{dbus}]
Return a service that runs the ``system bus'', using @var{dbus}, with
