@defvr {Scheme Variable} slim-service-type
This is the type for the SLiM graphical login manager for X11.
@defvr {Scheme Variable} gdm-service-type
This is the type for the @uref{https://wiki.gnome.org/Projects/GDM/, GNOME
Desktop Manager} (GDM), a program that manages graphical display servers and
handles graphical user logins. Its value must be a @code{gdm-configuration}
(see below.)
@cindex session types (X11)
@cindex X11 session types
SLiM looks for @dfn{session types} described by the @file{.desktop} files in
@file{/run/current-system/profile/share/xsessions} and allows users to
choose a session from the log-in screen using @kbd{F1}. Packages such
as @code{xfce}, @code{sawfish}, and @code{ratpoison} provide
@file{.desktop} files; adding them to the system-wide set of packages
automatically makes them available at the log-in screen.
GDM looks for @dfn{session types} described by the @file{.desktop} files in
@file{/run/current-system/profile/share/xsessions} and allows users to choose
a session from the log-in screen. Packages such as @code{gnome}, @code{xfce},
and @code{i3} provide @file{.desktop} files; adding them to the system-wide
set of packages automatically makes them available at the log-in screen.
In addition, @file{~/.xsession} files are honored. When available,
@file{~/.xsession} must be an executable that starts a window manager
and/or other X clients.
@end defvr
@deftp {Data Type} gdm-configuration
@table @asis
@item @code{auto-login?} (default: @code{#f})
@itemx @code{default-user} (default: @code{#f})
When @code{auto-login?} is false, GDM presents a log-in screen.
When @code{auto-login?} is true, GDM logs in directly as
@code{default-user}.
@item @code{gnome-shell-assets} (default: ...)
List of GNOME Shell assets needed by GDM: icon theme, fonts, etc.
@item @code{xorg-configuration} (default: @code{(xorg-configuration)})
Configuration of the Xorg graphical server.
@item @code{xsession} (default: @code{(xinitrc)})
Script to run before starting a X session.
@item @code{dbus-daemon} (default: @code{dbus-daemon-wrapper})
File name of the @code{dbus-daemon} executable.
@item @code{gdm} (default: @code{gdm})
The GDM package to use.

@defvr {Scheme Variable} slim-service-type
This is the type for the SLiM graphical login manager for X11.
Like GDM, SLiM looks for session types described by @file{.desktop} files and
allows users to choose a session from the log-in screen using @kbd{F1}. It
also honors @file{~/.xsession} files.
@end defvr
@deftp {Data Type} slim-configuration
Data type representing the configuration of @code{slim-service-type}.
