I'm completely new to Ubuntu and it's running great so far but the one issue that I've been having is that my laptop seems to heat up more than usual (even more than when I run windows!).

I only assigned about 1.8 gigs to my linux-swap partition (and I've heard that you should allocate double the amount of ram on your computer to this). Could this be the culprit of my overheating laptop?

I ran the lm-sensors utility to check the temperature of my cpu and it's been at about 67 degrees celsius and it says that the 100 degrees is critical. Is that a pretty normal temperature or should I be worried?

67 degrees is reasonable for a CPU. What exactly is overheating? – Nathan Osman Jul 20 '11 at 4:12
What is the value on Windows? What applications are you running, which version of Ubuntu? – user unknown Jul 20 '11 at 5:20

The heat may be coming from your video card, I've had the problem where my video card did not have supported drivers and was therefore running flat out 100% of the time. – Smithamax Jul 20 '11 at 9:05

@Smithamax: Hey, I tried to troubleshoot my problem again after a while and I believe that my problem is my video card. What did you do to solve your problem? – sq1020 Sep 26 '11 at 21:21

My problem was solved when my card got driver support in the ubuntu repo. I wasn't booting my laptop into ubuntu very often so i didn't worry me. I'd go onto your card manufactures website though and see if they have a more up to date linux driver. – Smithamax Sep 28 '11 at 3:20

Remove wheather plugin, disk-cpu-memory-plugin. Reduce graphic effects.

Can you edit this answer to explain in greater detail (perhaps even with screenshots) how to make these changes? – Eliah Kagan Sep 8 '12 at 1:37

You can also scale down your cpu to consume less power and thus produce less heat. A convenient way is described here: http://ubuntuguide.net/change-and-monitor-cpu-frequency-scaling-in-ubuntu-11-04-with-indicator-cpufreq

Another good way to reduce strain on your laptop is to install Jupiter Power Applet. This will give you tons more control over your battery, here's how to install.

  • Install PPA - sudo add-apt-repository ppa:webupd8team/jupiter & sudo apt-get update
  • Install Jupiter - sudo apt-get install jupiter
  • If you're on an EEEpc you'll have to install this as well - sudo apt-get install jupiter-support-eee

Hope this helps!

From personal experience i can tell that the user he is absolutely correct. There is a "more"-heating, not overheating problem. In windows i have 50 C while in ubuntu the normal is 60-62 C. I have been reading around, and there is a problem with the linux kernel. If you take a look at http://www.phoronix.com/scan.php?page=article&item=linux_31_power_regress&num=1 .
