This quick tutorial shows you how to easily create applications shortcut icons on your Ubuntu’s default Unity Desktop.
Due to permission issue, it’s not possible to drag and drop application shortcuts from the Unity Dash to the Desktop. You will get below error dialog when trying to do so:
As a workaround we can directly copy and paste the application shortcuts from /usr/share/applications directory into desktop.
1.) Open “Files”, Nautilus file browser, from the left Launcher and navigate to Computer (left panel) / usr / share / applications.
You will see all the applications’ icons there.
2.) Select one or more icons and press Ctrl+C to copy it/them. Then click on blank area of your desktop and press Ctrl+V to paste the icon(s). Note that drop and drop won’t work
That’s it, just so easy!
3.) For those who want to place Home, Network, Trash, and Devices icons on desktop, open Unity Tweak Tool (available in Ubuntu Software Center) from the Unity Dash and enable them from Desktop Icons utility.
