In previous question I asked how to disable zeitgeist Disabling Zeitgeist.
After I removed all packages, I was unable to find anything via unity launcher! Shortcuts to media apps, internet apps...dont work.
Reinstalling zeitgeist didnt help.
Any idea how to recover unity?
Fixed by installing unity add-ons: unity-place-applications and unity-place-files.
I can call this a bug: uninstall zeitgeist, install zeitgeist and you lose unity application and place files add-ons. They should be independent.
Run
unity --reset. You will lose all of unity's settings, but at least it should start working again.
