My "Most Frequently Used" Applications in Unity Dash disappeared.
I tried to:
- reset unity with unity --reset,
- removing Zeitgeist history with rm ~/.local/share/zeitgeist/activity.sqlite, and even
- reinstall zeitgeist via Synaptic,
but no one worked.
I also used Guest Session to check whether it only disappeared in my account, but actually not.
I don't know why it happened. How can I get it back? How do we reinstall unity and zeitgeist so that they really return to the state as when they are freshly installed?
Thanks in advance.
