I am using Ubuntu 12.10 currently. I have an ATI Mobility Radeon graphic card in my laptop. My laptop has heating problem. Laptop fan is always on. When I searched on the Internet, I found that this could be because of my graphic card driver.

On further searching, I found out about proprietary and open source drivers. Could someone tell me the pros and cons of both type of drivers? I want to know which driver I should install.

Output of lspci -nn | grep VGA is

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI RV710 [Mobility Radeon HD 4500/5100 Series] [1002:9553]

Finding the Pros and cons of using open source v.s proprietary drivers are very tough task. Many people have different views on this so it totally depends on the subject matter. For your case since AMD proprietary drivers are available, I suggest you to install them. Just go to this post and find the way to install AMD proprietary drivers.. – Saurav Kumar Oct 7 '13 at 9:20

I dont think your problem is driver-related.

The prime reason why laptops heat up is mainly because of dust deposits physicallty within the machine. This is not software related. Try finding a hardware expert and ask them to blow out duat from your machine. You can DIY by buying a laptop blower, unscrewing the back cover, and then blowing off the dust. Your laptop should be silent and also you fan will work less.

Also, another possible problem is because you sleep (suspend )your machine. Ubuntu is known to have issues with suspending and hibernation. I used to have the same problem, whereby my laptop's fan flew throughout when the machine was on, even with very few processes running. The problem ended after i had stopped hibernati ng my machine.

I don't think it's because of dust problem. It used to worked fine with Windows. – Neeraj Gangwar Oct 7 '13 at 16:12
