unity - Persistent Login loop 16.04.3

Received workstation with Ubuntu 16.04.3 LTS preinstalled from Dell.
Computer: Dell Precision 3630


Login loop immediately upon open box.


ctrl alt F1 works and I have access to 2 accounts I created and root


======================================================


contents of .xsession-errors


upstart: gnome-session (Unity) main process (2697) terminated with status 1


upstart: unity-settings-daemon main process (2689) killed by TERM signal


upstart: Disconnected from notified D-Bus bus


upstart: logrotate main process (2548) killed by TERM signal

unity7 pre-start process (2691) terminated with status 143


unity-panel-service main process (2613) killed by TERM signal


bamfdaemon main process (2614) killed by TERM signal


====================================================


Updated and upgraded ubuntu
edit /etc/lightdm/lightdm.conf and added:


allow-guest=false


greeter-hide-users=true


greeter-show-manual-login=true


sudo mv .xauthority .xauthority.bax
sudo dpkg-reconfigure lightdm
sudo restart lightdm

this did not fix the issue so:


ubuntu-bug lightdm


=============================


I have been searching all the login loop questions and have exhausted all avenues pointed out by the many answers. It seems that so many people have this issue with the unity greeter.


PS: I have 2 video cards and drivers:


Intel HD Graphics 630


AMD Radeon Pro WX2100
