Posted on by

The following tutorial describes how to change the background color / Ubuntu login screen wallpaper 21.10.

We will do everything in a few very simple steps.

We run the terminal and download the script:

1
wget https://github.com/PRATAP-KUMAR/impish-gdm-set-background/raw/main/impish-gdm-set-background

We give permission:

1
chmod u+x impish-gdm-set-background

And we do:

1
sudo ./impish-gdm-set-background --image PATH/TO/IMAGE


PATH/TO/IMAGE We replace the path to our picture. That's it 🙂

We can restore the default wallpaper by executing the command:

1
sudo ./impish-gdm-set-background --reset
