Yeah I have a laptop with intel/nvidia. I foolishly assumed it would work... several days of research and cursing later after installing ubuntu and I finally came to the realisation that the support just wasn't there. This was pretty recently too.
For what it's worth I just put an Ubuntu 14.04 nightly on my Nvidia Optimus laptop, and contrary to previous versions the dual-GPU setup Just Works (including choosing which GPU using the Nvidia utilities) after selecting the latest binary driver from the "Additional Drivers" page.
Quite a relief after fighting with the dual-GPU for so long.
