Double Monitor/Extended Desktop

[shaggytwodope]

Firstly, there is currently no means to do this natively with xfce desktop, it will be introduced in later versions. But you can install a simple tool called arandr.

sudo apt-get install arandr

It will then be located in your Menu, Menu > Settings >ARandR



You will then open arandr, navigate to Outputs > Display name > Activate. You can then use the gui to chose the placement of the display and hit the apply button (or ctrl+enter). If you run into any issues feel free to post again.
