To install Ubuntu with a working NVIDIA card on this laptop. Follow these instructions:

  1. Follow https://help.ubuntu.com/community/Asus_N53
  2. Add this to your modules blacklist in /etc/modprobe.d/blacklist.conf: 
    blacklist nouveau
blacklist fbcon
blacklist vga16fb
  3. Run 3D Graphics intensive applications like Google Earth with 
    optirun google-earth
  4. Optional: Mount Windows NTFS partition in /etc/fstab: 
    /dev/sda5       /d      ntfs    noexec,nosuid   0       0

Edit: You might not need to add the blacklist. I've just setup 11.04 64 bit and did not black list the drivers and it works! Remember to NOT enable the additional drivers in this setup because it will override your Intel Drivers, which are good because you can still run 3D apps but with less power consumption.
