For some unknown reason, my Unity dash doesn't show recent applications. I am guessing it could be related to the fact that I have a newer version of zeitgeist than the standard repo provides (I use a ppa).
That is the only unusual detail I can think of. What can I do to get back recent applications in the dash?
There was a similar problem reported here
The solution was to reinstall unity-lens-applications and unity-lens-files packages and the Dash magically works.
Both these packages were formely named unity-place-applications and unity-place-files
We are looking into it. Probably some packaging issue.
In my case none of the solutions above worked.
The solution I found to work:
sudo rm -rf ~/.local/share/zeitgeist
Then close your session and login again, and dash worked again.
for recent apps to show in dash in ubuntu 16.04 turning on record file and application usage (in security & privacy) worked for me
