I made a dual boot on my laptop with Windows 8. After installing Ubuntu, I notices that my laptop was really hot, and realized that both GPUs are working, my integrated Intel GPU and secondary NVidia. I found this solution http://techhamlet.com/2012/05/ubuntu-how-to-fix-over-heating-of-laptops-with-switchable-graphics/ and it really helped me, my computer stopped overheating instantly. But after some time, whenever I try to reboot, or work on my computer, it freezes, and on version 12.04.4 I wasn't even able to reboot it, it just froze on black screen saying something about kernel, nouveau, didn't really manage to remember all. Any suggestions? I think that it would work without changing rc.local, but I really don't want my computer to overheat.

Linux now supports Hybrid Graphics Systems. For Nvidia Hybrid Graphics you need following packages.

sudo apt-get install nvidia-319 nvidia-settings-319 nvidia-prime

you can find a review about the working and functioning of the Nvidia Hybrid Graphics on Ubuntu on Webupd8.enter image description here

Ok so I think that I solved this issue. I was researching a lot, and I found this: Switchable laptop graphics issues on Ubuntu 12.04?

I did this, I can feel that my laptop stopped overheating instantly after reboot, and I don't have any problems with booting Ubuntu. Also, there is another link that you could check if you have this problem: https://wiki.ubuntu.com/Bumblebee

So the solution would be to install bumblebee. If I encounter any more problems, I will edit this post.
