While X11 (see <xref linkend="sec-x11"/>) is still the primary display
technology on NixOS, Wayland support is steadily improving.
Where X11 separates the X Server and the window manager, on Wayland those
are combined: a Wayland Compositor is like an X11 window manager, but also
embeds the Wayland 'Server' functionality. This means it is sufficient to
install a Wayland Compositor such as <package>sway</package> without
separately enabling a Wayland server:
<programlisting>
<xref linkend="opt-programs.sway.enable"/> = true;
</programlisting>
This installs the <package>sway</package> compositor along with some
essential utilities. Now you can start <package>sway</package> from the TTY
console.

If you are using a wlroots-based compositor, like sway, and want to be able to
share your screen, you might want to activate this option:
<programlisting>
<xref linkend="opt-xdg.portal.wlr.enable"/> = true;
</programlisting>
and configure Pipewire using <xref linkend="opt-services.pipewire.enable"/>
and related options.
