Does anyone know how to set Ubuntu to an extended desktop over two monitors? I run a laptop with an intel graphics card.

I don't know how to get the actual name of the model of the card.


When I connect my extra monitor, Ubuntu recognizes it and clones my desktop, but it will not let me create an extended desktop.

Also: When I DO connect the external monitor, the feed goes in and out [as if Ubuntu is constantly rechecking to see that it's there]


Any help would be marvelous.
