Bash script that replaces the original login background from the distro with your own.
Use at your own risk! This was tested with Debian 4.14.13-1kali1
The script will make a backup, but make sure you make one as well in any case.
If you use multiple monitors, you might want to learn css and do this manually.

This script was created with snippets of code from ArchWiki.
- It unpacks the /usr/share/gnome-shell/gnome-shell-theme.gresource.
- It adds the new background to the css and xml files contained in the gresource.
- It compiles the gresource.
- It makes a backup of the original gresource and replaces it with the newly created one.
Please use .jpg files, it would make everything much more easier
chmod a+x changeTheme.sh
./changeTheme.sh
Why it asks me for 'sudo'?
Well, we need to change stuff in /usr/share/gnome-shell/ and we need root privileges to use cp and mv there.
My distro uses gdm3 but the script dosen't work.
Technically not a question, but open the script and change the variables so that they match your distro.
The variables you need to change are backgroundString and gst.
x.svg was not found.
I can't do anything about that, my solution was to make my own svg file with the same name and put it in shell-theme/theme folder.
And while inside shell-theme/theme manually running:
glib-compile-resources gnome-shell-theme.gresource.xml
sudo cp gnome-shell-theme.gresource /usr/share/gnome-shell/gnome-shell-theme.gresource
