After a successful upgrade to 14.04, now when I am trying to login using administrator id, It loops back to login page and doesn't load my session. Even guest is not working. When I enter wrong password for administrator, it shows invalid password label.

File name ~/.xsession-errors show below error

After upgrade to 14.04, I had changed the driver to NVIDIA proprietary for my GF119M [GeForce 610M] graphics card which was causing this issue.

I had to do a fresh installation of 14.04 and this time I continued with driver X.Org X Server (Open Source) from xserver-xorg-video-nouveau.

This resolved my issue.

Removing the ~/.Xauthority file then rebooting solved my issue.
