If you are using the proprietary nVidia driver, I believe that you
can
establish cloned screens through the nvidia-settings application. I'm not
sure if nouveau can do it, but you could try google:

Clone with 2 different res doesn't work like that. The lower res screen is just
one corner of the higher res - and most important - putting the image to be
projected into fullscreen mode will cause it to be fullscreen on the laptop -
not the projector.
