The File & Folders lens and default Applications lens is missing from my dock. How can I get them back?
I attempted the guide here: http://www.webupd8.org/2011/04/how-to-reset-unity-launcher-icons-or.html
All the icons came back except the two missing lenses. unity-place-applications and unity-place-files are both currently installed.
/usr/share/unity/places
? Have you tried reinstalling the packaged (sudo apt-get install --reinstall unity-place-files unity-place-applications
)?
