I found out the issue is with LDM (Light Display Manager) used with Ubuntu
11.11. I could do the following and get X going..
sudo service lightdm stop # Stop LDM
sudo service gdm start # Start the old Graphics display manager
after renaming custom.conf file in /etc/gdm which had auto log-on enabled.
How do I make 'gdm' my default login display manager?
BTW, The graphics card information on my laptop is as below.
