I cannot right click on the desktop

It was activating a few options of compiz config, but when it activates the option "wallpaper", to be able to have different images in every office. first I unite awhile the screen, which is normal, that in order that it works this option it is necessary to deactivate a thing in ubuntu tweak or in gnome tweak tool, after deactivating it works perfectly. But later I realized that when I right click on the desktop nothing happens. I found that for arregrarlo gconf-publisher had to open, go to apps > nautilus > preferences, and to activate show "desktop", but me this option does not appear, only it goes out saying:

desktop fond, navigation_window_saved_geometry, 
navigation_window_saved_maximized
start_with_sidebar.

Solution 1:

Or else, you can also use Ubuntu Tweak 0.7.1to do the same. Simply download and install it by running these one by one from a terminal:

sudo add-apt-repository ppa:tualatrix/ppa
sudo apt-get update
sudo apt-get install ubuntu-tweak

Then start Ubuntu tweak, go to Tweaks menu, select Desktop Icons, and change Show Desktop Icons to On. Basically it does the same thing as what

gsettings set org.gnome.desktop.background show-desktop-icons true

does, but Ubuntu Tweak can also come in handy if you need some system-tweaking quickly, without using complicated codes.

Thanks.

Solution 2:

Try this:

Hit Alt+Ctrl+T to open terminal and run following command:

gsettings set org.gnome.desktop.background show-desktop-icons true
