I've upgraded to Raring a couple of days ago, and noticed that certain indicators are not appearing in my Unity panel, while all other do.

Essentially I'm referring to: pyAlienFX (from http://code.google.com/p/pyalienfx/), Thunderbird (with Firetray extension, https://github.com/foudfou/FireTray.git) and pidgin.

Obviously they all did work with previous 12.10.

The older system tray has been retired since 10.04 and has now been totally removed in 13.04. pyalienfx needs to use the appindicator, you can file a bug on the program and point to this page:

So that app authors can port their application. This includes a fallback option so the software will still work in older Ubuntus and other distros.

As far as pidgin and thunderbird, those are integrated into the messaging menu (The little envelope).

Here are some other pointers:


Here's my solution:

How to re-enable the systray whitelist in Ubuntu 13.04 (Raring Ringtail)

If you use such an application and want the systray whitelist back in Ubuntu 13.04, you can use a PPA that comes with Unity patched to re-enable the systray whitelist. To do this, open a terminal and run the following commands:

sudo add-apt-repository ppa:timekiller/unity-systrayfix
sudo apt-get update
sudo apt-get upgrade

Then, restart Unity by pressing ALT + F2 and entering "unity" or by logging out. Then open Dconf Editor, navigate to com > canonical > unity > panel and the "systray-whitelist" should be displayed there so you can enable some apps to be able to use the systray.

After adding an application to the systray whitelist, remember to restart Unity or else it won't work.

    You should realise this installs a custom version of Unity. You are now dependent upon the PPA owner for updates & fixes.
