After logging into my Wi-Fi network then logging out then logging back into the Live-USB session Two Wi-Fi network applets appeared where One would be the expected outcome.

Confirmed on Lubuntu 18.04 32bit @ 12/4/18 on daily iso, after a succesfull install
2 wifi icons showing at right down corner

Since the older bug (1685502) was marked duplicate in favor of this one, I'll just copy a few related links (aside from the listed duplicates) that might be of interest:

Would be nice to finally see this fixed across all Ubuntu flavors, but maybe that's not possible due to different approaches (panels).

[fabritrento (fabritrento)]

the same problem is present in xubuntu 18.04LTS, two wifi icons is displayed in the panel

[aaronfranke (arnfranke)]

Occurs for me on live session and installed versions of release Xubuntu 18.04 Bionic Beaver. Two network icons are displayed, both functional.

System specs: TL-WDN4800 Wi-Fi card, i5-6600k, 16 GB RAM, GTX 770.

[bmaupin (bmaupin)]

Same here, on an installed Xubuntu 18.04

[tom581 (tbrown581)]

I've got the same problem in Xubuntu 18.04. Two network icons appear in the panel.
When I restart the Xfce Panel (xfce4-panel --restart), one of the two duplicate icons goes away but it comes back especially when I resume the system after suspend.

[Pascal A. (pascalav)]

Also present on Lubuntu 18.04 (from a 16.04 upgrade, at least).

[Pascal A. (pascalav)]

Maybe an hint:
  - The first network icon has no sections horizontal bar UI-delimiters (e.g. between the 'Wifi' and 'Mobile broadband' sections)
  - The second network icon has those UI-delimiters

[Prahlad Yeri (prahladyeri)]

This happens on Xubuntu and UbuntuMATE variants of 18.04.01 LTS too, its high time that this needs a resolution.

Title of this bug is:

[QUOTE] Two Wi-Fi network applets appear after logging back into live-usb Lubuntu 18.04 session. [/QUOTE]

However, this also affects Lubuntu 18.04.1 installed to my HDD; not just live-usb.

[bmaupin (bmaupin)]

In Xubuntu this may be fixable by removing the indicator-application package:

sudo apt remove indicator-application
xfce4-panel -r

[Alkis Georgopoulos (alkisg)]

It appears to be a race condition, like maybe nm-applet first registers itself in the tray, then indicator-applet-complete is loaded, and it shows nm-applet a second time. While if nm-applet starts after indicator-applet-complete has finished loading, it doesn't register itself in the tray, only in the indicator-applet-complete itself.

But I'm experiencing this very rarely so I can't easily test workarounds.

If you add "X-GNOME-Autostart-Delay=10" in /etc/xdg/autostart/nm-applet.desktop, does the problem go away?

[Alkis Georgopoulos (alkisg)]

And another test would be:
In /etc/xdg/autostart/nm-applet.desktop
to replace:
Exec=nm-applet
with:
Exec=nm-applet --indicator

...which hopefully turns off autodetection and always uses indicator-applet-complete. Does that work?

[schamane (schamane)]

I tried `Exec=nm-applet --indicator` on a Lubuntu 18.04 w/ current updates. After reboot still 2 icons were shown on the panel.

[Mark smith (zebiddy8)]

Two network & volume indicators also on XFCE panel.
No change even after resetting the panel (xfce4-panel -r).
I guess two is better than none. ;-)

[Alex (alex2020)]

Xubuntu 18.04. In the settings panel remove the Status Notifier Plugin. Only one network icon will remain.

[Ilias (ilias63)]

Xubuntu 18.04.2
Two network icons appear at start up but not every time.
The 1st icon appears because Status Notifier plugin is enabled.
The 2nd icon appears because nm applet and network are included in Notification area and if I choose to be hidden only the arrow appears in panel instead of the 2nd icon.
Under 16.04 there was no problem ever.
xfce-panel -r solves the problem but not permanently.
Any idea on this issue?

[John Doe (j0hn1d0e)]

Thanks to Alkis Georgopoulos @alkisg for the hint, `Exec=nm-applet --indicator` indeed does work for me in LUbuntu 18.0.4.

[Josep Pujadas-Jubany (jpujades)]

Lubuntu 18.04.3 LTS 64 bit fresh install & dist-upgrade on:

* Toshiba Satellite Z30-B-15M
* Acer TravelMate B115-M

I have the same problem. Tried:

Exec=nm-applet --indicator

or

X-GNOME-Autostart-Delay=10

in /etc/xdg/autostart/nm-applet

Not working. Two icons in most logins.

[Josep Pujadas-Jubany (jpujades)]

Exec=/bin/bash -c "sleep 2 && nm-applet"

in /etc/xdg/autostart/nm-applet

seems to be a good workaround for my computers.

Both computers are using SSD disk. So, fast start-up.

[Sebastien Bacher (seb128)]

it's not a bug in nmapplet if lubuntu includes 2 indicators

[Alkis Georgopoulos (alkisg)]

In Ubuntu MATE 18.04, this happens in e.g. one out of 10 logins (not just in the Live CD).

We tried uninstalling the indicator-application package in 500+ schools.
The problem never occurred again.

If this can't be pinpointed, maybe Ubuntu MATE and Lubuntu can just avoid including the indicator-application package in the default installations.

Isn't that about extracting the application menus and putting them in the panel? This isn't used by default, right?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Peter Eijlander (peter-eijlander)]

This happens too in Linux Mint MATE 19.3 (in my case 64bit) Stopping and starting the applet does not help but logging off and back on again soves this iommediately. It occurs since the change from the old separated applets to the "unified XApp Status Applet" combines the status of updates and network. Simulating it is hardly possible, it's more a gamble.

[Martin Wimpress  (flexiondotorg)]

Fixed in ubuntu-mate-settings (21.04.1) hirsute;

[Alkis Georgopoulos (alkisg)]

I still have the issue in Ubuntu MATE 22.04.
Removing ayatana-indicator-application (which replaced indicator-application) works around the issue.
