Adding Truecrypt to Ubuntu's Unity panel

To add applications like Truecrypt to Ubuntu’s Unity panel the application has to be “white listed”.

  1. Install dconf-editor (ie sudo aptitude install dconf-editor)

  2. Go to section desktop | unity | panel and add ‘Truecrypt’ to the systray-whitelist variable

  3. Restart Unity (or log out and back in again)

That’s it. Found this solution here.
