I'm afraid you cannot simply connect your laptop to your desktop as if it was a TV or desktop monitor, because laptops generally only provide video outputs but no video inputs.
One might be able to pull something like that off by using a complex setup of Xdmx, synergy and probably some virtualisation/remote access software or protocols (e.g. spice) to get a virtual second screen on the desktop and to display it on the laptop (and access the laptop from your desktop via synergy). Of course this also comes with a huge computing overhead.
I don't know of any hardware solutions that would allow something like that, but I guess they would be almost as expensive as another desktop monitor.
