Hi,

Best way to-do this and one that is reversible if needed.

- Open terminal.
- Do: 'cd /usr/share/gnome-shell/theme'
- Do: 'sudo cp -f noise-texture.png noise-texture.png.orig'
- Pick a wallpaper that is 'png' and the same resolution as your screen.
- Do: 'sudo cp -f /path_to/my_image.png noise-texture.png'

You may need to experiment with the size of the image to match your
resolution.

To reverse the changes:

- Do: 'cd /usr/share/gnome-shell/theme'
- Do: 'sudo cp -f noise-texture.png.orig noise-texture.png'
- Do: 'sudo rm -f noise-texture.png.orig'

Regards

Phil
