Ubuntu install and switch Nvidia dual graphics driver method

Ubuntu system installed Nvidia driver, you can switch dual graphics in the settings. The performance mode switches to a discrete graphics card, while the power save mode switches to the integrated graphics. Here's how to install Ubuntu and switch Nvidia dual graphics drivers.

First, Ubuntu installs Nvidia driver

Ubuntu's private driver library is restricted to Nvidia's official graphics driver. We can easily use apt-get or graphical Ubuntu 14.04 software. Installation in the center:

sudo apt-get install nvidia-331 nvidia-settings nvidia-prime

As with Windows, installing a graphics driver requires a reboot to take effect.

Nvidia's official website also provides driver installation programs for Linux, such as the latest stable version 331 for 64-bit Linux.

However, individuals still recommend to install directly with apt-get, apt-get will automatically choose to install 32-bit or 64-bit drivers according to the system type, and the drivers in the restricted library are generally tested by Ubuntu. It is more stable and easier to operate.

Nvidia Graphics Control Panel nvidia-settings shortcuts are located at /usr/share/applications/nvidia-settings.desktop

You can link one to the desktop for easy graphics setup.

Second, Ubuntu dual graphics switch

You can also directly run Alt+F2 nvidia-settings to open the control panel, such as viewing the graphics card temperature under Thermal Settings, and switching between PRIME Profiles.

With nvidia-prime, you don't need bumblebee. You can switch between graphics cards in Nvidia's official control panel nvidia-settings, which is very convenient.

in the open Nvidia card GPU temperature is 40 & deg; C, CPU temperature is 41 & deg; C, as shown below:

does not play a large 3D games or watching HD video without It is recommended that you switch from "Nvidia Performance Mode" to "Intel Energy Saver Mode".

In the Intel energy-saving mode, the Nvidia graphics card is automatically turned off to save energy. In addition, Intel's nuclear display itself has a good hardware acceleration capability, usually using Intel nuclear display.

For example, this MacBook on the Jingdong is only equipped with an i5 CPU and uses Intel IRIS Graphics for hardware acceleration.

Many other Ultrabooks are only equipped with Intel low-voltage processors and use the built-in HD Graphics.

Intel has integrated its graphics driver into the Linux kernel project, so there is no need to install an additional Intel graphics driver, out of the box.

If you don't need to use the single display for a long time, you can boot into the BIOS and change the Graphic Mode from Switchable to Integrated to disable the display.

The above is how Ubuntu installs and switches Nvidia dual graphics drivers. The biggest benefit of Nvidia dual graphics switching is that it maximizes the performance of the computer game while also balancing system power savings.
