Ubuntu – Missing system tray icons Ubuntu Gnome 18.04

18.04gnomesystem-tray

I have Ubuntu 18.04 and I am using the default Gnome. I updated and all of the system tray icons were missing.

Is this a bug? Can this be fixed? I cannot see any of the unread messages that I have in Skype / Slack etc. And there is no way to know about missed notifications.

Does someone know how to fix this issue?

You may also simply try to relaunch gnome shell and see if it works better:

(Alt+F2) gnome-shell --replace

Or the short and easy way

(Alt+F2) r (Enter)

Yes, just the letter "r".

If I restart the shell the icons come back, to do so:

press alt + f2

type "r" without quotes

hit enter

This is not a solution but a quick workaround. I believe it affects the icons of all the programs that depend on QT.

I opened a bug report and this is the address: https://bugs.launchpad.net/ubuntu-gnome/+bug/1594550

Ubuntu – Ubuntu Budgie 18.04 LTS System Tray Icons not all showing

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.
