1# Xfce Desktop Environment {#sec-xfce}
2
3To enable the Xfce Desktop Environment, set
4
5```nix
6{
7 services.xserver.desktopManager.xfce.enable = true;
8 services.displayManager.defaultSession = "xfce";
9}
10```
11
12Optionally, *picom* can be enabled for nice graphical effects, some
13example settings:
14
15```nix
16{
17 services.picom = {
18 enable = true;
19 fade = true;
20 inactiveOpacity = 0.9;
21 shadow = true;
22 fadeDelta = 4;
23 };
24}
25```
26
27Some Xfce programs are not installed automatically. To install them
28manually (system wide), put them into your
29[](#opt-environment.systemPackages) from `pkgs.xfce`.
30
31## Thunar {#sec-xfce-thunar-plugins}
32
33Thunar (the Xfce file manager) is automatically enabled when Xfce is
34enabled. To enable Thunar without enabling Xfce, use the configuration
35option [](#opt-programs.thunar.enable) instead of adding
36`pkgs.xfce.thunar` to [](#opt-environment.systemPackages).
37
38If you'd like to add extra plugins to Thunar, add them to
39[](#opt-programs.thunar.plugins). You shouldn't just add them to
40[](#opt-environment.systemPackages).
41
42## Troubleshooting {#sec-xfce-troubleshooting}
43
44Even after enabling udisks2, volume management might not work. Thunar
45and/or the desktop takes time to show up. Thunar will spit out this kind
46of message on start (look at `journalctl --user -b`).
47
48```plain
49Thunar:2410): GVFS-RemoteVolumeMonitor-WARNING **: remote volume monitor with dbus name org.gtk.Private.UDisks2VolumeMonitor is not supported
50```
51
52This is caused by some needed GNOME services not running. This is all
53fixed by enabling "Launch GNOME services on startup" in the Advanced
54tab of the Session and Startup settings panel. Alternatively, you can
55run this command to do the same thing.
56
57```ShellSession
58$ xfconf-query -c xfce4-session -p /compat/LaunchGNOME -s true
59```

61It is necessary to log out and log in again for this to take effect.
