I have added a background image to unlock screen of 18.04 using the below code in ubuntu.css in usr/share/gnome-shell/theme

#lockDialogGroup { background: #2e3436 url("unlock-background.jpeg"); background-repeat: none; background-size: cover; }

While it works great, is it possible to add a blur effect to whatever image we are using as unlock screen background ? Thanks.

Eg. Something close to the blur below

enter image description here

Possible solution from w3schools

/* Add the blur effect */
  filter: blur(8px);
  -webkit-filter: blur(8px);

I am not quite confident how to add this piece of CSS.

An easy way is to blur your image using GIMP or an online tool and then use the blurred image as a background.

If you don't know how to use GIMP, i would recommend using this: https://onlinejpgtools.com/blur-jpg

Just upload your image, enter the blur radius you want and download the resulting image.
