Many applications still uses the old system tray implantation. This guide will show you how to enable it on elementary OS.
Open the terminal and copy/paste the following;
sudo apt install software-properties-common sudo add-apt-repository ppa:yunnxx/elementary sudo apt update sudo apt install indicator-application wingpanel-indicator-ayatana
The next thing is to add Pantheon to your autostart/indicator-application.desktop
sudo nano /etc/xdg/autostart/indicator-application.desktop
You’ll find a line called OnlyShowIn=Unity;GNOME; add Pantheon; to it. It should now look like;
OnlyShowIn=Unity;GNOME;Pantheon;
Save: [ctrl]+[o]
Exit: [ctrl]+[x]
There’s a bug that will show you two network indicators in your system tray.. To correct it, copy/paste;
cd /etc/xdg/autostart sudo rm nm-applet.desktop
Reboot
Enjoy! ^_^
TESTED on: elementary OS 5.1.4
