Solve the UBUNTU14 fan high-speed rotation problem (dual graphics)

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)

installing the NVIDIA Prime

1. Find "Additional Drivers" in "System Settings" – "Software and Updates". The default is to use the open source Nouveau driver. Here we choose the NVIDIA 331 driver.

2. Installing the NVIDIA 331 driver

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

3. Install NVIDIA Prime dual graphics switcher

sudo add-apt-repository ppa:nilarimogard/webupd8sudo apt-get updatesudo apt-get install prime-indicator

4, restart the computer, the system tray is more than an Nvidia icon, indicating that the current selection of graphics card is unique, point "quick switch graphics" can quickly switch the video card.

a quicker way.

Installing the Bumblebeecan also solve the problem of fan turning.
