Setting up dual monitors, Xorg.conf issues

Question

I just got a new computer (W520, Graphics card nVidia GF106 [Quadro 2000]) and installed ubuntu on it using wubi. I have everything working, so I wanted to set it up to be able to use two monitors with an extended screen. I figured I had to edit Xorg.conf, but the file didnt exist. So I tried to create it by booting in recovery mode, and executing

 Xorg -configure

but I am getting these errors:

(EE) Failed to load module "vmwgfx" (module does not exist, 0)
(EE) vmware: Please ignore the above warnings about not being able to load module/driver vmwgfx
(++) Using config file: "/root/xorg.conf.new"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
(EE) [drm] No DRICreatedPCIBusID symbol
Number of created screens does not match number of detected devices.
    Configuration failed.
  ddxSigGiveUp: Closing log

Any idea how I can get Xorg -configure to work, so that I can have an xorg.conf file that I can edit to enable twinview?

EDIT:

Another way I could ask the same question to solve this problem is, why can't I boot with an xorg.conf file generated by nvidia-xconfig? Is there something in the generated xorg.conf file that might need editing?

EDIT:

So it seems like I have bigger issues. I have an nVidia Optimus technology which seems like it precludes me from running Unity 3d. At least all of the information I can find on it says that. This is from forums as recent as January of this year. Has there been any new developments? Can I have dual monitors while running unity 2d?

EDIT:

I am going to ask another question because this problem seems to be a symptom of my larger issue.

Answer 1

You shouldn't really need to worry about xorg.conf. You need to install your nvidia drivers. The first thing you need to do is login normally, hit SuperKey and type in: Additional DriversOpen the Additional Drivers. You should see the following:

Select the one of your choice, and hit activate. The drivers should download for you, and install. Once the download/installation is complete, it will let you know that you will need to restart.

Once restarted you should then have access to the Nvidia X Server Settigns Application. You'll be able to find it by hitting SuperKey again and typing in: nvidia

You can then go to:

Hit Detect Displays, Set the Resolution, and Twinview or with one of your displays (whichever you prefer) set to primary.

I have access to a W520 at work. Let me know if this helps or if you need a little more info and I'll try to see what I can do to add more detail.
