Hi @mickee,

/usr/share/backgrounds/ubuntu-mate-jammy/Jammy-Jellyfish_WP_4096x2304_Green.png is a part of ubuntu-mate-wallpapers-jammy package. If this package gets reinstalled, your modifications will be lost. Path to login screen background is stored in /usr/share/glib-2.0/schemas/30_ubuntu-mate.gschema.override file.
