On Ubuntu 13.04, in the login screen there are white dots arranged in a pattern which some people might always want to get rid of. Today I am going to show you how to eliminate all those dots.
Why? Because we can! It’s very simple. Let’s get started.
Open your terminal and copy and paste the following commands in their respective order into the terminal and press Enter after each:
$ sudo xhost +SI:localuser:lightdm
$ sudo su lightdm -s /bin/bash
$ gsettings set com.canonical.unity-greeter draw-grid false
Type exit to change user.
Restart the computer to see the changes.
To restore the white dots, run the commands in step 1 and 2 above.
Then run this command:
$ gsettings set com.canonical.unity-greeter draw-grid true
Restart the computer to effect changes.
