Sync GDM screensaver/lockscreen picture with Wallpaper

[brx75]

Add the option to keep Gnome screensaver picture in sync with wallpaper.

This is easily achieved by doing something like this:

    FILEURL=$(gsettings get org.gnome.desktop.background picture-uri)
    echo "$(date -Is): Session background is set to: $FILEURL"
    gsettings set org.gnome.desktop.screensaver picture-uri "$FILEURL"
    echo -n "$(date -Is): Lock screen has been set to: "
    gsettings get org.gnome.desktop.screensaver picture-uri

Just as a note, it is probably worth combining this feature with the option to sync the wallpaper with LightDM.

I agree, this would great! Been trying to get lockscreen wall to update with desktop to no avail. On ubuntu 18.04, gnome 3.28.2.
