Hi Ben, I know I have optimus, and we are trying a module to be able to switch between screens, you can check it here: git://<a href="http://github.com/awilliam/asus-switcheroo.git" target="_blank">github.com/awilliam/asus-switcheroo.git</a> I will try to get better debug and see why I get a black screen... This error is not significant then???

However, I'd say you've probably got an Optimus laptop, which means you're out of luck. Only the intel GPU is physically wired up to the display..
