I installed Cryptkeeper on my Ubuntu 11.04, but when I run it, the only way to manage it is through the icon it places in the top desktop bar, or Panel. You know that top desktop bar that used to hold my wonderful applet icons, yeah this one:
Ubuntu 11.04 64 bit (Natty Narwhal)
So if you want to see your icons in the top bar again, run this command from the Terminal, and once you’re done log out and back in:
gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"
End of Line.
