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..<br><br>sudo service lightdm stop # Stop LDM<br>sudo service gdm start # Start the old Graphics display manager<br>
<br>after renaming custom.conf file in /etc/gdm which had auto log-on enabled. <br><br>How do I make 'gdm' my default login display manager?<br><br>BTW, The graphics card information on my laptop is as below.<br>

Start with looking in your /var/log/Xorg.0.log for errors.<br>
Next, I found Ubuntu troublesome when trying to install video drivers,<br>
so there could be a kernel driver mismatch or something. apt-get update<br>
&& apt-get upgrade to make sure everything is updated and installed.<br>
For instance today I loaded Mythbuntu, which defaulted to Nvidia 175.x<br>
driver. I enabled the repo for 285.x (or whatever # it is) and<br>
installed it, but 175 just stayed as the working driver. I'm no Ubuntu<br>
expert, so there was probably a trick to getting it working, but in the<br>
end I just removed the 175 driver which made the nvidia-current (285)<br>
become the working driver.<br>
