Anything about Ubuntu, Centos, openSuSe and Fedora
Initially, since Ubuntu 11.04, I tried Unity several time and force myself to like it, but I can’t. Done several tweak to make it useful then, but when 12.04 came out, Unity if getting more usable and faster.
And another thing about Unity, is that I hides several icons from the default system tray, most of them place under the messaging menu icon ( the one that looks like a mail envelope), which includes pidgin, a multi-platform instant messaging client. I’ve tried several howtos to show it back to the system tray, but still I failed. Then read this acticle from ask ubuntu (here), and it works!.
1. Via the console/terminal while under your login account, invoke:
$> gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"
2. You can also use dconf-editor, which is included in the dconf-tool package, install it using either the “Ubuntu Software Center” or via console with the command:
$> sudo apt-get install dconf-tools
3. On dconf-editor, go to Desktop -> Unity -> Panel, and replace the value of systray-whitelist to “[‘all’]”.
