How to Convert the Unity Launcher into a Dock-Style Launcher

00_lead_image_dock_launcher

The Unity Launcher in Ubuntu is locked to the left side of the screen. If you would rather have a launcher at the bottom of the screen, there is a way to convert the Unity Launcher into a dock-style launcher at the bottom of the screen.

First, we will be installing the Unity Tweak Tool and Cairo-Dock. To install the Unity Tweak Tool, click the Ubuntu Software Center icon on the Unity Launcher.

01_opening_ubuntu_software_center

Start typing “unity tweak” in the search box in the upper-right corner of the Ubuntu Software Center window. Results start to display in the list as you type. When the “Unity Tweak Tool” displays in the list, click on it and then click the “Install” button.

02_clicking_install_for_unity_tweak_tool

When the “Authenticate” dialog box displays, enter your password in the “Password” edit box and click “Authenticate.”

03_authenticate_dialog

The progress of the installation is displayed on the right side of the “Unity Tweak Tool” item in the list.

04_installation_progress

Now, search for Cairo-Dock and install it using the same procedure we described for installing the Unity Tweak Tool.

05_installing_cairo_dock

When the installation of Cairo-Dock is finished, click the X button in the upper-left corner of the Ubuntu Software Center window to close it.

05a_closing_ubuntu_software_center
To open the Unity Tweak Tool, click the icon on the Unity Launcher.
06_opening_unity_tweak_tool_from_unity

NOTE: If you don’t have an icon on the Unity Launcher for the Unity Tweak Tool, open the Dash and type “unity”. The Unity Tweak Tool icon should display under “Applications” in the results. Click the icon to start the tool.

07_starting_unity_tweak_using_dash

In the “Unity” section of the Unity Tweak Tool, click “Launcher.”

08_clicking_launcher

On the “Launcher” tab, click the “Auto-hide” switch so it reads “ON.” The Unity Launcher immediately hides. You can change the “Auto-hide animation,” “Reveal location,” and “Reveal sensitivity” as well.

09_turning_auto_hide_on

To start Cairo-Dock, move your mouse to the left side of the screen (or top left corner, depending on your settings) to show the Unity Launcher. Then, click the Cairo-Dock icon on the launcher.

10_running_cairo_dock

The Cairo-Dock displays at the bottom of the screen. For more information about customizing and using Cairo-Dock.

11_cairo_dock_visible_unity_hidden

If you want Cairo-Dock to display automatically when you log in, right-click anywhere on the dock and move your mouse over “Cairo-Dock.” Then, select “Launch Cairo-Dock on startup” from the sub-menu that displays.

NOTE: Once you select the “Launch Cairo-Dock on startup” option, it is removed from the menu. If you change your mind and don’t want Cairo-Dock to start automatically when you log in, you can disable it in the Startup Applications tool.

12_selecting_launch_cairo_dock_on_startup

This method of switching to a dock-style launcher gives you the best of both worlds. You can have a dock at the bottom of the screen and still access the Unity Launcher by hovering your mouse over the left side of the screen.
