1. Open terminal and type
- Code: Select all
2. Open /var/lib/menu-xdg/applications/menu-xdg from that window. Files will have name something like this "X-Debian-Games-Toys-oclock.desktop"(This file will be shown as oclock application in Gnome shell). Delete the files having extension .desktop whose icons are displayed twice(In my case I deleted all files).
3. Open /usr/share/applications
4. Delete duplicate icons or unnecessary icons from here.
Hopefully this will solve your problem
Note: Instead of deleting files, move them to a new folder placed at different location as deleting files may cause problems or shortcuts may be needed in future.
