I have HP DV6 6080 laptop with Sandy Bridge ci7 CPU and ATI graphic.

I have thermal issue and power usage in Ubuntu. I followed the instructions from this tutorial to install hybrid graphic because I want to my laptop become cool in Ubuntu.

But after doing so, my laptop thermal doesn't become cool. I tried to install new kernel 3.4 in order to fix these issues but after installing, it doesn't boot in high graphic mode and need to me reconfigure graphic.

How can I reconfigure graphic? And how can I fix thermal issue in my laptop with 12.04?

I've had a dv7 for years (I think from Ubuntu 10.04). Of course it is not Sandy Bridge, but I have the same issue. After a lot of tries during these years I understood there is nearly no way to avoid the heat. But this is normal and doesn't harm your laptop.

Important note: This is a personal experience on a laptop different than yours. May be you were more lucky than me and find a good way on your computer.
