That itself set the context of your upcoming work or activity that you are about to do. Although, I am not a Windows fan, but I admire how Windows 10 login background changes every day from Bing wallpapers, and it looks nice. Isn’t it? + +A while back, we covered how to [change login background in Fedora][1] and [elementary OS][2]. And now this guide explains how you change it in vanilla Ubuntu with GNOME Shell. + +Login screen background is part of display manager property. This guide uses a script in GitHub created by a user to make it seamless and easy for average user. Otherwise, you have to change the Gnome Display Manager (gdm) CSS files manually after extracting the `.gresource` file, then compile it – which is complicated in general. + +![Ubuntu Login screen - before change][3] + +Ubuntu Login screen – before change + +### Change Login Background in Ubuntu + +- Open a terminal (press CTRL+ALT+T) + +- Download the [GitHub repo][4] using the below command. + +``` +wget github.com/thiggy01/change-gdm-background/raw/master/change-gdm-background +``` + +**Note**: If you do not have wget, install it using `sudo apt install wget` + +**Ubuntu 22.04 Jammy Jellyfish** users require an additional code change to make it work because the developer did not fix it in GitHub.

Then, go to the following line (#15) and add `|jammy`. + +![script change to allow jammy][5] + +script change to allow jammy + +Then, go to the following two lines (#144 and #184). Change `gdm3.css` to `gdm.css`. As shown below. + +![correct the css file for gdm][6] + +correct the css file for gdm + +And finally, save the file and follow the instructions as below. This workaround is only for Ubuntu 22.04 login screen change. + +- Change the permission of the script to make it executable + +``` +chmod +x change-gdm-background +``` + +- Then change the login background wallpaper in Ubuntu using the below command. Change the path of your image. + +``` +sudo ./change-gdm-background ~/Pictures/tree.jpg +``` + +This step might require `libglib2.0-dev` package, which will be installed automatically. This is required to extract/compile the `.gresource`. + +And after installation, it would prompt you to restart gdm. Press N, to be on the safe side. + +- Log out and you can see the changed background in Ubuntu. +- If you are not seeing the change, try restarting your system and then try to log in. + +![Ubuntu Login screen After Change][7] + +Ubuntu Login screen with background After Change + +### Restore the stock login screen + +The script also provides a feature to revert the stock login screen. It takes a backup of your `.gresource` file before changing it. So, from the terminal, simply run below to restore the original login screen. + +``` +sudo ./change-gdm-background --restore +``` + +That should change the login screen back to its original form. + +Let me know whether it worked for you using the comment box below.
