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:
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.
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.
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.
