Previously I explained the procedure of adding a Gwibber lens to the Unity Launcher, which enables checking for Gwibber updates from the Dash. While it can be fun to add lens to Unity, adding too many lens can clutter the launcher. In this post I will explain the procedure involved in removing a Lens from the Unity launcher, as well as purging it from your Ubuntu system.
To get started, enter the following system path in a Terminal window.
gksudo nautilus /usr/share/unity/places
This will open the folder containing all the installed lens.
Open the file of a lens that you wish to delete e.g. “gwibber. place” and paste the following below “Shortcut=..”. For example, if you are removing the gwibber lens, the respective text within the file will look like “Shortcut=g”.
Restart Unity, hit enter ALT+F2, enter the following in the Dashboard and click on Unity – -replace.
Finally, Log off and log back in. The Lens will be removed from the Unity Launcher. To remove the lens completely from the system, go to to the Ubuntu Software Center and type the initials of the lens name to find and remove it completely.
