I am using Fedora 18 in my laptop with Nvidia GT 630M graphics card. I am using dual boot with windows 7.
In windows I am getting a battery backup of around 3 hr. But when I use Fedora, it reduces to 1 hr. It also produces excess heat.
After searching a lot on power saving, I used many tools like powertop. But it doesn't make any difference.
Then I came to know that nvidia GPUs are poorly supported in Linux and it can produce high heat due to excess use of GPU.
So below is the data I got on GPU usage from powertop.
Does this value denote a high GPU usage ? How can I reduce this problem for a better battery backup and lesser heat production?
UPDATE (PROBLEM SOLVED):
I followed @allquixotic answer and it worked. I tested my computer for temperature and battery backup.
sensors shows around 50 C which means 8-10 C reduction in temperature. (ie great).
And now I get 3 hr full videoplayback battery backup, and that is awesome (earlier it was less than 1.5 hr without videoplayback)!!!
So in short, BumbleBee works fine in Fedora 18 !!!
