I have Skype installed for my Ubuntu 14.04. And I have added it to indicator-messages (com>canonical>indicator>messages). But now I can't find a way to remove Skype icon from unity panel. I tried to add Skype to unity-gtk-module blacklist, but that doesn't help. Is there a way to forbid an application to show it's icon on panel?
You can remove it by:
sudo apt-get remove sni-qt sni-qt:i386
Note that removing
sni-qt will affect other apps that depend on it (such as dropbox) to show their icons. If you do not want this to happen, there is a detailed work-around posted in How can I remove the Skype panel icon?
