I have tried several ideas such as:
chown pi:pi .Xauthority choxn -R pi /home/pi
and I have deleted .Xauthority
But my pi keeps returning to the Shut-Down / Log-In screen no matter what I do.
I can get to terminal (ctrl-alt-F1) and do what ever I want, but the desktop won't finish loading.
Password is correct and working, just returns to the same screen.
