Значить так, оптимусдрочеры, слушаем сюда:

The driver may be installed normally on Optimus systems, but the NVIDIA X driver 
and the NVIDIA OpenGL driver may not be able to display to the laptop's internal 
display panel unless a means to connect the panel to the NVIDIA GPU (for example, 
a hardware multiplexer, or "mux", often controllable by a BIOS setting) is available. 
On systems without a mux, the NVIDIA GPU can still be useful for offscreen rendering, 
running CUDA applications, and other uses that don't require driving a display.
On muxless Optimus laptops, or on laptops where a mux is present, but not set to drive 
the internal display from the NVIDIA GPU, the internal display is driven by the 
integrated GPU. On these systems, it's important that the X server not be configured 
to use the NVIDIA X driver after the driver is installed. Instead, the correct driver 
for the integrated GPU should be used. Often, this can be determined automatically by 
the X server, and no explicit configuration is required, especially on newer X server 
versions. If your X server autoselects the NVIDIA X driver after installation, you may 
need to explicitly select the driver for your integrated GPU.

В двух словах - трахайте мозги своему производителю БИОСа и говнобука!!!
Трахайте мозг себе - потому, что перед покупкой не изучили документацию, в том числе на BIOS!  

Если кто ещё скажет про не работу Оптимуса - можете смело причислять его к жирному троллю,
школьнегу, лошаре, "мимопроходил",...
