Right-clicking on the Unity desktop does nothing - ideas?

It is highly unlikely the N.E. is a real problem.

Ensure that:

/apps/nautilus/preferences/show_desktop enter image description here (run gconf-editor) Is set to true. If it is, also ensure that nautilus is set to launch on login.

  • How do I use the gconf editor?

The desktop is actually provided by Nautilus, just like it was in previous versions of Ubuntu. If you press Alt+F2 and type killall nautilus without the quotes and then press Enter, this will stop (and automatically restart) Nautilus.

What happens when you right-click on your desktop then?
