# Xfce Desktop Environment

To enable the Xfce Desktop Environment, set

     = true;
     = "xfce";
    };

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

    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 .

## Thunar Volume Support

To enable Thunar volume support, put

     = true;

into your configuration.nix.

## Polkit Authentication Agent

There is no authentication agent automatically installed alongside Xfce. To allow mounting of local (non-removable) filesystems, you will need to install one. Installing polkit_gnome, a rebuild, logout and login did the trick.

## Troubleshooting

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 `journalctl --user -b`).

    Thunar:2410): GVFS-RemoteVolumeMonitor-WARNING **: remote volume monitor with dbus name org.gtk.Private.UDisks2VolumeMonitor is not supported

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.

    $ xfconf-query -c xfce4-session -p /compat/LaunchGNOME -s true

A log-out and re-log will be needed for this to take effect.
