I am the developer of Login Manager Settings and I want my application to be able to set blurred background for GDM.
It can change GDM background by modifying gnome-shell.css
found in gnome-shell-theme.gresource
I tried adding
filter: blur(8px);
to gnome-shell.css
, it didn’t work. Is there any way to do this that I don’t know?
What program does gnome-shell
use to parse its CSS?
Also, I know I can use ImageMagick to modify the image directly but ImageMagick is slow and I would prefer not to use it.
