Unhide system tray icons on Ubuntu 12.04 Unity

I had couple of applications like Uget downloader, Truecrypt, Data card dialers for Reliance Netconnect, Tata Photon+, etc. which would run in background if you close (click on cross - X) them.

And at times, I needed to bring them to front for different reasons. By default, you do not see any system tray icons in Unity unlike on GNome, Mate or any of other desktop environments.

So here is how do you bring back system tray icons in Unity.

Run

user@ubuntu:~$ gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" user@ubuntu:~$

..............Done!!!

PS: If changes doesn't show up immediately, run

user@ubuntu:~$ unity --replace
