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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761606 Title: Two Wi-Fi network applets appear after logging back into live-usb Lubuntu 18.04 session.
