Ever since I installed Ubuntu 12.10 I've been having overheating issues, and poor battery life. Jupiter indicates that my CPU is 45° while idle, and 65-75° while performing common tasks.

My battery lasts for like an hour and a half.

I asked a similar question before:

How to improve battery life on a HP Pavilion dv6?

DrA7 pointed out that it might be a problem related to having hybrid Intel/ATi GPu,I tried to use the proprietary drivers using "Software sources" but Ubuntu always boots in low graphics mode or something like that: here's a snapshot, notice what happens when I try to open catalyst control centre.

CCC

I read this interesting article, and attempted to install the driver provided by AMD, but I had no luck with that either.

Also: I'm not sure if this is relevant but this is what happened when I ran sudo aticonfig --initial while using fglrx -updates driver.

error

My laptop is an HP pavilion dv6 6185la.

Thanks for your answers, this is the only thing that's keeping me from switching to Ubuntu completely.

You're not alone. I switched from Windows 7 to Ubuntu hoping to solve random freeze issue (that remained even after a full factory reset with HP provided CDs). The computer overheats on its own, just boot and wait. –  ixe013 Mar 28 '13 at 13:26
    
@ixe013 Hi, I managed to "solve" this issue after all by installing an app called Jupiter, and most importantly by disabling the ATI card that comes with our computers, this is the cause of the overheating, it has to do with some bug with the open source driver and ATI/Intel hybrid cards : take a look at this post link –  user1793249 Apr 3 '13 at 0:22
