This about Asus' UL80Vt (some type of hardware)
CULV processors are typically paired with Intel's GS45 Express chipset, whose integrated Graphics Media Accelerator X4500MHD offers abysmal gaming performance and spotty compatibility. Fortunately, the chipset has 16 lanes of second-generation PCI Express connectivity, which the UL80Vt links to a GeForce G210M discrete graphics processor. Toggling between the GeForce G210M and GMA X4500MHD is as easy as switching between power plans, which can be done with the touch of a button located above the keyboard. The process isn't entirely seamless; the screen goes blank for a few seconds when you switch graphics modes. (http://techreport.com/articles.x/17939) I want to use linux or XP, but so can't enable G210, driver show me that the display is not connected to G210. May be we need to use some special util to swith GPUs.
