customizing the background of gnome3 login screen

:: debian, jessie, gnome, gdm

gnome conf tools on debian jessie, such as dconf-editor, are not robust at present, and it’s not straightforward to customize the background of gnome3 login screen. modifying the default background of gnome3 login screen on debian jessie can be done by editing file /usr/share/gnome-shell/theme/gnome-shell.css.
