Sets GDM background image while blurring it and changing brightness.

Works well with Blur my Shell extension. (Brightness and blur parameters correnspond to 'Blur my Shell' ones. Not perfectly, however, but closely)

Until such feature is implemented in future releases of GDM or Gnome, this script serves as a nice workaround

gdm-settings is a thing now, but still no blur ;(

• Python 3

• Pillow

pip install Pillow

• Tkinter

• gdm-tools
