Many of the forum and on stack overflow I found people are facing problem and asking about the solution. Well if you are looking for this solution then you are on the right page.
You may need to follow two steps for getting icon back on the tray:-
1. Install the sni-qt libraries.
Install sni-qt (click on the link), or with
sudo apt-get install sni-qt sni-qt:i386 from the terminal, and then restart Skype. The tray/panel icon should now be back!
The reason this step is required is because sni-qt is installed automatically by the Ubuntu repository Skype package, but NOT by the Skype deb you directly download. Once Skype 4.0 is in the Ubuntu repos, you can install from there and this will no longer be necessary.
2. You may also need to whitelist the indicator.
I don’t know why, but for some systems this additional step is required before the indicator will show
- Install the package
dconf-tools(click on the link), or from the terminal with
sudo apt-get install dconf-tools
- Open dconf editor from the Dash (or
- On the left sidebar, use the triangles to navigate to desktop > unity > panel. On Ubuntu 12.10 you instead need to navigate to com > canonical > unity > panel. Double-click on the orange
[JavaEmbedded...]part on the right, and add
,'skype'to allow the Skype indicator to show, as below:
- Press Enter, close dconf editor, logout and login — your indicator should now be back!
