Hello, I am not sure... But insane the Optimus architexture needs the Integrated Card to be on all the time the NVIDIA is in use (to write to it´s memory). In my opinion it´s an ugly hardware design. Or I am wrong ? Vgaswitcheroo enables switching on my Asus N53jf. But do so is resulting in thre old screen which isn´t updated any more. It looks the main Problem is to get the NVIDIA/Nouveau driver writing in the Intel ?Framebuffer?. Where is this function located ? In the Mainboard BIOS, VGA BIOS, Win7 diver ? And which way the Data took ? Through sli or PCI ? How the find the Call... Am 21.12.2010 12:03, schrieb Dave Airlie:

I hear that some Optimus enabled laptops have some kind of a pre-windows 7 compability mode in the BIOS... Does anyone have an idea how this is archived on the hardware side???Its the same as the pre-optimus hw, most of the pre-optimus announced hw could actually support optimus as well since its mostly a sw soln.
