nVidia Optimus is a technology from nVidia for switching the discrete nVidia card off when the graphical power of it is not needed and relying on the integrated GPU from Intel. Unfortunately, this technology is not supported on Linux yet and nVidia has no plans to support this.

Due to the design of the hardware (the GPU is wired to the CPU instead of the bus), the discrete cannot even be used if there is no BIOS option available for disabling this technology.
