Found the following two entries had been added to /etc/apt/sources.list 
following automatic updates.
deb [trusted=yes] http://ftp.us.debian.org/debian experimental main
deb [trusted=yes] http://ftp.us.debian.org/debian sid main

Commented them out and performed apt update. Then purged the following packages:
apt purge gnome-settings-daemon gdm3 gnome-control-center gnome-initial-setup 
gnome-power-manager gnome-shell uatter ubuntu-desktop ubuntu-session

This removed these packages, then reinstalled all pre-existing packages.

Reboot returned system to normal functionality.
