Ubuntu – How to solve overheating problem

dellnvidiaoverheatingtemperature

I have windows 7 and ubuntu 12.10 installed.
My laptop specs are
Dell XPS 15
4gb RAM
Nvidia gt540m

I've been searching for hours but can't figure out a solution. I am a complete newbie to ubuntu. I've installed tlp but the only thing I was able to do with it was to know my cpu temperature is 75C. I executed sudo tlp start but there hasn't been any change in temperature.

I too use Dell XPS 15 and have suffered from over-heating in past when I used open source nvidia-nouveau (installed from additional drivers).

Problem got solved when I started using bumblebee where you can manually switch between intel graphics and nvidia graphics. Nvidia graphics gives much better performance but is also power expensive which results into overheating. Bumblebee gives you option to use only graphic heavy applications with nvidia graphics thus reducing overheating.

Guide to Install Bumblebee

After installation you can run any application with nvidia graphics by using optirun <application-name> from terminal.

Also you can try indicator-cpufreq which lets you put your profile to conservative, also reduce CPU frequency from applet-icon to prevent overheating when computational load is low.

I think battery management on Ubuntu is just fine. To improve it, however, you can install Jupiter. According to WebUpd8.Org,

Jupiter is an appindicator (it now uses Python instead of Mono) designed to improve laptops / netbooks battery life. It can be used to switch between maximum, high performance and power saving modes, change the screen resolution and orientation, enable or disable bluetooth, touchpad, WiFi (if available) and so on. If you own an Asus EeePC netbook, there's also a separate package that adds support for Asus Super Hybrid Engine (SHE) as well as some other EeePC tweaks.

To install Jupiter, enter the following commands:

sudo add-apt-repository ppa:webupd8team/jupiter
sudo apt-get update
sudo apt-get install jupiter
