Move the launcher on the left side of the Ubuntu16.04 desktop to the bottom of the screen

Press Ctrl + ALT + t keyboard key combination to bring up the terminal, enter the following command in the terminal:

Gsettings Set Com.canonical.Unity.Launcher launcher-position Bottom

Press ENTER.

The last Bottom in the command is the meaning of the bottom.

Pull up the terminal again and enter the following command:

Gsettings set Com.canonical.Unity.Launcher launcher-position left

Note either the Bottom in the previous step or the left in this step, the first letter is capitalized.

You will find the Launcher launcher back to the left of the screen.

If you change the last parameter of the above command to right, Launcher will not move anywhere. It appears that the above command can only switch the location of the Launcher between the left and the bottom of the screen.
