Delete extra toolbar on top of the screen in GNOME fallback mode?

Solution 1:

Try to install Gnome-Tweak-Tool (Click to install), and go to "Desktop" and then change the "Have file manager handle desktop" to off.

You could install gnome-tweak-tool via Software Center or sudo apt-get install gnome-tweak-tool

Hope it helps.

Solution 2:

The gnome-tweak-tool solution turns off everything put on the desktop like linked folders and files, which is unacceptable for me. I use the desktop as part of my work space.

That extra toolbar (Global Menubar) is part of the Unity desktop. Remove Unity and the toolbar is gone. This article shows you how to remove all aspects of the Unity.

Here are the relevant command from that article to solve this problem:

• Remove the appmenu. The appmenu (or Global Menubar) is that function that brings up the menu 'panel. Since we are going to remove unity, becomes useless (and also a problem because there would appear under the menu panel nautilus gnome)

  sudo apt-get purge appmenu-gtk appmenu-gtk3 appmenu-qt indicator-appmenu
  

• To remove more Unity parts:

  sudo apt-get remove unity-lens-music unity-lens-applications unity-greeter unity-common unity-asset-pool unity-2d-launcher unity-2d libunity-misc4 libunity-2d-private0 gir1.2-unity-4.0
