Ubuntu – Producing lot of heat and fan sound, while using ubuntu 12.04 on dell xps-l502x


I have installed Ubuntu 12.04 in my XPS L502. Everything works fine except the system heat. I can feel that the laptop heat rises more and fan sound also, when I am using ubuntu. But with Windows 7 that came pre-installed with laptop heat is normal. I like to use Ubuntu on this laptop, but because of this reason I am not able to do that. Please help.

I had the same problem. I solved it by installing Bumblebee.

It seems like it was a problem with power management. After installing Bumblebee and restarting my computer, it ran smoothly, with quiet fan and at normal temperature. Actually, now my battery last longer in Ubuntu than it does on Windows 7.
