I installed Xfce in Ubuntu 14.04, but the network manager icon disappeared. When I run sudo nm-applet, the icon shows. Not only the network manager but also the power manager and fcitx icon disappeared. fcitx is a Chinese input method.

For the benefit of further readers having the same problem I would like to note that I managed to get the indicators to show up in the xfce4 indicator area without using the indicator plugin.

I fiddled with the settings, but I think the key point was to deactivate the gnome indicators that I marked with red in the screen shot. I reckon these are gnomish programs that might indeed need the indicator-plugin. As can be seen at the top right of the screen shot, at least the network manager and the power indicator appear. Whether there is something special for bluetooth in xfce4, I don't know.

Test this:
Edit /etc/xdg/autostart/nm-applet.desktop:
sudo su
nano /etc/xdg/autostart/nm-applet.desktop
Go down to the Exec line.
Change the entry:
nm-applet
to
dbus-launch nm-applet
Save the file -- Control + O
Close nano -- Control + X
Reboot.
Login and you will see that the n-m icon is now back.

In my case, I needed to install network-manager, and network-manager-gnome, despite the fact that I use using xfce4.
sudo apt install network-manager
sudo apt install network-manager-gnome
sudo systemctl enable NetworkManager.service
I rebooted the system, and the network manager plugin appeared in XFCE4's tray.
Thanks for the tip with network-manager-gnome. Strangely, the xfce4-netload plugin no longer displayed anything, so WLAN could no longer be used. As described, the applet installed. Reboot. Works. MX XFCE 23 Libretto
sudo apt install network-manager-gnome
sudo systemctl enable NetworkManager.service
network manager was already installed.
you can also make the network-manager applet show up with systemd, just make sure you have a notification area set
- make a file
~/.config/systemd/user/nm-applet.servicewith the following content: -
[Unit] Description=Network Manager Applet[Service] ExecStart=/usr/bin/nm-applet
[Install] WantedBy=graphical-session.target
- start it with
systemctl --user start nm-applet
