I'm using qz-tray application installed/downloaded from GitHub: qzind/tray.

It does not show tray icon in Ubuntu 18.04 Gnome desktop.
What should I do to show it?

    Do you have gnome-shell-extension-appindicator package installed? What is the output of apt policy gnome-shell-extension-appindicator? Are you in a "vanilla" GNOME session by any chance?

    May be related askubuntu.com/questions/1030833/… . What application you use? For example hplip-gui and psensor show their icons on clean installation of standard 18.04 LTS. But guake does not show its icon.

I ran the following commands to install QZ Tray (based on official guide):

sudo apt-get install git ant nsis makeself default-jre
cd ~/Downloads
wget https://github.com/qzind/tray/releases/download/v2.0.7/qz-tray-2.0.7.run
chmod +x qz-tray-2.0.7.run
sudo ./qz-tray-2.0.7.run
  • At first I tested it in normal traditional desktop - Ubuntu MATE 18.04 LTS and it has tray icon in place here just after installation:

    qz-tray MATE

  • Then I switched to Ubuntu 18.04 LTS with GNOME:

    1. With default settings it is not shown (i.e. gnome-shell-extension-appindicator is installed, enabled and loaded).
    2. Then installed TopIcons Plus extension from GNOME Software - it shows icon in non-expected place (note green printer near Firefox icon and black square near clock):

    QZ Tray with TopIcons Plus

    1. Afterwards I removed TopIcons Plus and installed TopIcons extension - it does not work even if I start it manually with java -Xms512m -jar "/opt/qz-tray/qz-tray.jar".

So I recommend to drop this brave new GNOME world and switch to fully functional traditional MATE desktop environment by executing sudo apt-get install ubuntu-mate-desktop^.
As normal users we do not have time to overcome all these new non-predicted difficulties.
Also you can try to find support on GitHub issue page to fix this problem for GNOME.


Starting with 2.0.9, QZ Tray detects the absence of a System Tray and attached to the Taskbar icon instead.

Here's QZ Tray running on ElementaryOS:

Solutions including the System Tray compat libs (or avoiding Gnome entirely) are the correct solution for those using older QZ Tray versions, however those looking to use a newer version of QZ Tray no longer need to make special considerations. It should work out of the box.
