I don't know if this has been solved or not, and I didn't see it. I'm a complete noob to Ubuntu Budgie and I have 18.04 LTS with the latest updates.

I have Dropbox, Mega, and a few other things installed that are not showing in the System Tray at any point. Dropbox did for a little bit, but then it's gone. Mega, Thunderbird, qBittorrent, don't show up at all. pCloud and Skype show up right now, also when I turn on Franz it shows up.

Can someone please help? I'm sure this has been solved before but I'm not sure what's going on.

    on simple Ubuntu 18.04.1 I just logged out and switched to Ubuntu on Wayland and than everything worked as expected in tray. Maybe this helps someone else. – fuser Sep 2 '18 at 15:21

This problem is common for both Ubuntu 18.04 and Ubuntu Budgie 18.04.

The reason of issue is lack of the libgtk2-appindicator-perl package in main Ubuntu 18.04 repository. A workaround is to install libappindicator-dev:

sudo apt install libappindicator-dev

and Gtk2::AppIndicator perl extension:

sudo cpan -i Gtk2::AppIndicator

Restart your applications, now all of missing icons have to appear in system tray.

    This solved the problem once but the icons disappeared after rebooting. – dmishra Oct 22 '18 at 9:07

    it does not work for me. Neither the dropbox, nor the variety's icon appeared in the system tray. I tested it with Ubuntu 18.04 and Debian 9 with same result. – Zoltán Süle Dec 20 '18 at 22:26

    It does not work on Linux Mint 19.1 issue :( – kokbira Feb 12 '19 at 20:03

    Wow, couple of commands that started half an hour rebuilding of something... and don't seem to have worked. – jayarjo Mar 8 '19 at 8:48

Here is the bug in Launchpad:


It says 18.10, but I see exactly the same thing in 18.04. The workaround described in this works: Alt+F2, r, Enter (restarting the window manager).

An update to this: the issue was fixed and the fix released a while ago now. I haven't had the issue reoccur since.

  • What's that command prompt that Alt+F2 brings up? – jayarjo Mar 8 '19 at 8:46

    This worked, and didn't require a reboot like the accepted solution. – Étienne Mar 12 '19 at 12:32

    @jayarjo it's literally a command prompt. You can type commands in it (and a couple of secret shortcuts like 'r'.) – Robin Sheat May 28 '19 at 13:18

Using budgie settings ensure you have the appindicator applet added to your panel.

A few applications show their panel icons as application indicator and not as a traditional system tray icon.

You could launch budgie desktop settings from terminal:

$ budgie-desktop-settings

This settings manager is inside of budgie-desktop package. You could find all related packages by invoking a command:

$ apt-cache search budgie-desktop

To add what you want go to Top Panel section, click the Add applet 'plus' button and choose what you need. Bugie Desktop Settings applet adding to panel picture

(I could not comment @fossfreedom's answer)

His tip solved the issue for me, but I had to install a package manually before. So, if you are using "vanilla" Ubuntu 18.04 or 18.10 with Budgie Desktop, assert that the AppIndicator Applet is installed. If not:

  1. Install the package budgie-indicator-applet
  2. Restart the session
  3. Add the AppIndicator Applet to the panel (preferably, right next to System Tray)

If you have any open application that uses it (ex.: Dropbox), the icon should show up.
