+Linux Systems Using nVida Drivers
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This guide is for users of the proprietary Nvidia driver on Linux Distributions.
+It is assumed that you have properly setup your drivers according to your
+distribution's documentation, and you have a working xorg.conf file in place.
+
+If you wish to make the changes permanent in setting up your system for dual
+monitors it will be necessary to modify your xorg.conf file. It is always a good
+idea to make a backup of any critical file before making changes::
+
+  user@linux:~ $ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old 
+
+or for those using systems that use the root user instead of sudo, change to 
+root and enter::
+  
+  root@linux: # cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old 
+
+The exact location of the xorg.conf file can vary so check your distribution's 
+documentation.
+
+If you want to make your changes permanent run nVidia settings from the terminal::
+
+  user@linux:~ $ sudo nvidia-settings 
+
+or::
+
+  root@linux: # nividia-settings 
+
+If you do not want to write the changes to your xorg.conf file simply run the
+nVidia Settings program from your desktops menu, usually in an administration
+or system menu, or from the terminal as a normal user run::
+
+ user@linux:~ $ nvidia-settings 
+
+Once you have opened nVidia Settings, click on **X Server Display Confiuration**
+Then select the monitor you are wanting to use as your second monitor and click
+configure.

+
+After clicking configure, select twinview. Then click ok.

+
+Then click **apply** and if you are happy with the way things look click to keep
+your new settings. Don't worry if all goes wrong the settings will return back
+to the previous settings in 15 seconds without any action. nVidia Settings
+should take care of selecting your optimum resolution etc, but that can be 
+changed as needed. When you are happy with everything click on **Save to X Configuration File**
+
+.. image:: pics/xorgwrite.png
+
+Then click **Save** and you should be set. You may want to restart X or your 
+machine just to make sure all the settings carry over the next time you log in.
