Problem Description

Since my dual-card laptop has been installed on Ubuntu 14, the fan has turned into a huge heat. Online One search is estimated that the graphics card driver is not very line. The Nvidia prime of Nvidia has recently been able to seamlessly switch between dual graphics cards, and after installing the software, the fan will not turn wildly and the heat will not be as big. (My computer is g710+hd4000)
