Use Bumblebee to control NVIDIA dual-graphics (ubuntu)

Use Bumblebee to control NVIDIA dual-graphics card (ubuntu) Introduction Nvidia dual-graphics card switching technology is called Optimus (Optimus Prime), but unfortunately it can only be implemented under win7 and vista. There is no corresponding technology in Linux, and of course Apple does not. This causes the independent video card to be enabled all the time, the video card is heated up, and the fan turns crazy, but there is no normal input. Usually, the laptop battery can be used for 4 hours in Win7, and it takes about two hours for Ubuntu to run out. AMD has already developed a catalyst for Linux for the ATI graphics card. It supports switching between card a and intel. N card users can only talk about it. Optimus technology does not rely on the complex hardware structure of the crossfire graphics card implementation. Independent graphics cards are rendered on demand and transmitted to integrated graphics cards. Integrated graphics cards are used for display. When the notebook is powered by power, the independent graphics card is turned off to prolong battery life. Bumblebee tries to simulate the behavior of Optimus technology. When needed, it uses an independent video card for rendering and disables it when not used. The current version only supports on-demand rendering, and the power management function is still under development. Test environment: Acer Aspire 5750 GNVIDIA GeForce GT630Mubuntu 12.04 x86_64 I.
