I have Ubuntu 11.10 (Oct, 2011).

I never use Unity-2d.

I downloaded various Lenses from the Software Center. Then I restarted the system.

But I don't see any differences! What do I have to do?


Lenses need to be stored in /usr/share/unity/lenses. Open that folder and you'll see that each lens is stored in it's own folder. At a minimum there will be a {lens name}.lens file. You will probably need to log out and log back in for the new lens to be recognized.


Some lenses doesn't show up in Dash. For example, if you install the Calculator Lense, it will only appear if you type for example "2 * 3" on the search box. Some have "tabs" bellow the Dash. Just click on them and them you can make your search.

  • Yes, I now that. For example I download, like others Lense, the Calculator Lense and when I type in the dash "2 * 3" or things like that, I wait and wait and wait but nothing appears! The Lenses don't work!! Were I can install the Lense? Those that are available in the Software Center I installed and didn't work. – Lucio May 9 '12 at 22:33
  • Try to use alt + f2 and write "unity --replace" – joelalmeidaptg May 10 '12 at 11:19
