How can I change the window shadow size for windows in the gnome shell?
I'm trying the shell out and I like it so far. I know it uses mutter rather than compiz so there's no ccsm that I'm used to.
But I understand you can configure almost everything within /usr/share/gnome-shell via css and js. Awesome
Anybody know where the window shadow line is?
You can only edit the Shell theme via /usr/share/gnome-shell, not the windows. As far as I know, you must edit the mutter source code, and this might become quite difficult if you don't know programming.
(Not tested)
Edit the theme manually by adding the following to ~/.config/gtk-3.0/gtk.css:
Use values to suit :)
