To enable the Xfce Desktop Environment, set
|

<programlisting>
|

services.xserver.desktopManager = {
|

xfce.enable = true;
|
||
default = "xfce";

Optionally, <emphasis>compton</emphasis>
|

can be enabled for nice graphical effects, some example settings:
|

<programlisting>
|

services.compton = {
|

enable = true;
|
||
fade = true;
|
||
inactiveOpacity = "0.9";

shadow = true;

fadeDelta = 4;
|

};

Some Xfce programs are not installed automatically.
|
||
To install them manually (system wide), put them into your
|
||
<literal>environment.systemPackages</literal>.

NixOS’s default <emphasis>display manager</emphasis> is SLiM.
|
||
(DM is the program that provides a graphical login prompt
|
||
and manages the X server.)
|
||
You can, for example, select KDE’s
|
||
<command>sddm</command> instead:
|
||
<programlisting>
|
||
services.xserver.displayManager.sddm.enable = true;
|

</programlisting>

<para>
|

To enable
|

<emphasis>Thunar</emphasis>
|
||
volume support, put
|
||
<programlisting>
|
||
services.xserver.desktopManager.xfce.enable = true;
|

</programlisting>
|

into your <emphasis>configuration.nix</emphasis>.

<title>Polkit Authentication Agent</title>
|
||
|
||
<para>
|
||
There is no authentication agent automatically installed alongside
|
||
Xfce. To allow mounting of local (non-removable) filesystems, you
|
||
will need to install one.
|
||
|
||
Installing <emphasis>polkit_gnome</emphasis>, a rebuild, logout and
|
||
login did the trick.

|
||
Even after enabling udisks2, volume management might not work.
|
||
Thunar and/or the desktop takes time to show up.
|
||
|
||
Thunar will spit out this kind of message on start
|
||
(look at <command>journalctl --user -b</command>).
|
||
|
||
<programlisting>
|
||
Thunar:2410): GVFS-RemoteVolumeMonitor-WARNING **: remote volume monitor with dbus name org.gtk.Private.UDisks2VolumeMonitor is not supported
|
||
</programlisting>
|
||
|
||
This is caused by some needed GNOME services not running.
|
||
This is all fixed by enabling "Launch GNOME services on startup" in
|
||
the Advanced tab of the Session and Startup settings panel.
|
||
Alternatively, you can run this command to do the same thing.
|
||
<programlisting>
|
||
$ xfconf-query -c xfce4-session -p /compat/LaunchGNOME -s true
|
||
</programlisting>
|
||
A log-out and re-log will be needed for this to take effect.
