Chapter 17. Using the NVIDIA Driver withOptimus Laptops
Some laptops with NVIDIA GPUs make use of Optimus technology toallow switching between an integrated GPU and a discrete NVIDIAGPU. The NVIDIA Linux driver can be used on these systems.
Installing the NVIDIA Driver on an Optimus Laptop
The driver may be installed normally on Optimus systems, but theNVIDIA X driver and the NVIDIA OpenGL driver may not be able todisplay to the laptop's internal display panel unless a means toconnect the panel to the NVIDIA GPU (for example, a hardwaremultiplexer, or 'mux', often controllable by a BIOS setting) isavailable. On systems without a mux, the NVIDIA GPU can still beuseful for offscreen rendering, PRIME render offload, running CUDAapplications, and other uses that don't require driving adisplay.
On muxless Optimus laptops, or on laptops where a mux ispresent, but not set to drive the internal display from the NVIDIAGPU, the internal display is driven by the integrated GPU. On thesesystems, it's important that the X server not be configured to usethe NVIDIA X driver after the driver is installed. Instead, thecorrect driver for the integrated GPU should be used. Often, thiscan be determined automatically by the X server, and no explicitconfiguration is required, especially on newer X server versions.If your X server autoselects the NVIDIA X driver afterinstallation, you may need to explicitly select the driver for yourintegrated GPU.
Nvidia have announced Advanced Optimus, a new way to get the best of both worlds between integrated and discrete graphics in laptops. Let’s recap how Optimus previously worked, and see how the new Advanced Optimus improves this design. How Optimus previously worked. NVIDIA Optimus technology intelligently optimizes your notebook PC, providing the outstanding graphics performance you need, when you need it, all the while extending battery life for longer enjoyment.
As an alternative to using only the integrated graphics device,support for the display output source functionality provided by theX Resize and Rotate extension version 1.4 is available. Thisfunctionality allows for graphics to be rendered on the NVIDIA GPUand displayed on the integrated graphics device. For information onhow to use this functionality, see Chapter 33,Offloading Graphics Display with RandR 1.4.
If you have an iGPU and a dGPU (i.e. Intel HD and Nvidia GT/GTX) in a laptop, you basically have Nvidia Optimus. The Nvidia Optimus tech basically switches out iGPU and dGPU (turning on and off one between the other) usage on-demand based on the tasks you're doing. The objective is to enable NVIDIA GPU of an Optimus-based laptop all the time and use it for every single activity. Please do not use this guide if you want to render your desktop using the integrated GPU and specifically select applications to be rendered using the NVIDIA GPU. Right now, only certain laptops have Optimus technology, although the number is growing daily. Though Nvidia Optimus automatic switching does help conserve battery life, it doesn't guarantee great.

A second alternative is to use PRIME render offload, such thatthe integrated graphics device is used to drive the X screen, butthe NVIDIA GPU is used on a per-application basis to acceleraterendering of specific applications. For details, see Chapter 34,PRIME Render Offload.
Loading the Kernel Module and Creating the Device Files withoutX
In order for programs that use the NVIDIA driver to workcorrectly (e.g.: X, OpenGL, and CUDA applications), the kernelmodule must be loaded, and the device files /dev/nvidiactl and /dev/nvidia[0-9]+ must exist with read and writepermissions for any users of such applications. If the setuid rootnvidia-modprobe(1) utility is installed (the default when thedriver is installed from .run file), this should be handledautomatically. Otherwise, the kernel module will need to be loaded,and the device files created, through your Linux distribution'smechanisms.
See “How and when are theNVIDIA device files created?” for more information.
