After reading up on the threads that many users whom have problems with the nvidia driver installation, i got my own system to install the drivers properly.
1) Download the nvidia driver from Nvidia.com. Choose the version according to your system specs. http://www.nvidia.com/object/unix.html
2) I noticed that nvidia now has included a little program to help u to configure ur Xorg.conf file. Choose No when it prompts u to do so.
3) When you have booted back into Linux, type /etc/X11/xorg.conf
4) Remove the line:
and replace it with the line:
Remove the following lines:
In the Module section of the file, add the line (if it does not already exist):
Save the settings you have made and reboot. You should see Nvidia logo when you boot into Linux again. If you do not see it, it means you probably never install the driver properly.
