How to change login screen background in Ubuntu
You may get bored with ordinary purple-colored background screen whenever you login into your computer. To replace this purple-colored background to your favorite background screen it is not as easy as in Windows.
Steps to change login screen background in Ubuntu:
Step 1: Copy your favorite background image and paste in below mentioned folder:
/usr/share/backgrounds
or type this command in terminal and enter your password.
sudo cp Path_of_Image/NAME_OF_THE_FAVORITE_IMAGE /usr/share/backgrounds/
Step 2: We need to modify a CSS file which is responsible for the background image. Open the terminal and paste this command and you will able to see a CSS file.
Step 3: Press ctrl+f and you will see insert box at top right corner of the window. Type #lockDialogGroup in the box then you can see the “#lockDialogGroup” highlighting on the screen.
Step 4: Find out the following section.
#lockDialogGroup {

background: #2c001e url(file:///usr/share/backgrounds/NAME_OF_THE_FAVOURITE_IMAGE);
background-repeat: no-repeat;
background-size: cover;
background-position: center; }
Write your image name in place of “NAME_OF_THE_FAVORITE_IMAGE” in the above section and save the file.
