== Ubuntu dual monitors ==

Run &lt;code&gt;nvidia-settings&lt;/code&gt;.  Now we may need to modify the Xconf file, if so see the following:
# Open nvidia-settings by searching for nvidia in the Dash, or run the command gksudo nvidia-settings in the Terminal. Note not to press the apply button.
# Under 'Xserver Display Configuration' select TwinView and configure the settings for the monitors to your liking.
# Click 'Save to X Configuration File' and an error message should appear. Click OK.
# In the next dialog box click the button to 'Show Preview'.
# Leave the preview window open and open a Terminal. Run the following commands in the Terminal to back up your xorg.conf file and open the original file in a test editor. If something goes wrong, just revert to your backed up xorg.conf.
# sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
# gksudo gedit /etc/X11/xorg.conf`
# Copy the text from the nvidia-settings preview window into the xorg.conf file. Save the xorg.conf file and close gedit. Click 'Cancel' to close the nvidia-settings preview window. Then click 'Quit' to exit completely out of nvidia-settings without applying or saving any data.
# Restart your computer. If all went well, the two monitors should work together.

Note: As of ubuntu 12.04 you don't appear to need to copy the xorg.conf files around.  Just clicking save is all it takes.
