After GNOME was officially introduced with Ubuntu 17.10, Ubuntu 20.04 is the 6th Ubuntu release, and only the 2nd Ubuntu LTS release to use it instead of the previously used Unity. Due to the ease of use and an ample number of extensions and customizations available, GNOME has been well received within the Ubuntu users’ community.

A new GNOME Extensions app has been introduced in Ubuntu 20.04, which makes it even more easier to customize the desktop. In this article, we will see how to use this app to disable the Ubuntu Dock.

Installing GNOME Extensions App

The GNOME Extensions App is a part of the package gnome-shell-extensions. This package will install the app along with all the available GNOME extensions.

sudo apt install gnome-shell-extensions

Verify the installation by running:

gnome-extensions version

Disable Dock from Command Line

Run the following command to get list of available GNOME extensions.

gnome-extensions list

To disable the Ubuntu dock, run:

gnome-extensions disable

This will immediately remove the dock from the screen. Similarly, you can use the enable command to re-enable the dock.

Disable Dock from GUI

Go to Activities on the top left corner, and search for Extensions.

Disable the Ubuntu dock by switching the toggle button to Off. Also, make sure the Extensions toggle button is enabled on the title bar of the window.

Here is how the desktop looks like without the dock.

You can switch the toggle button back to On, to re-enable the dock.
