Comment 31 for bug 836480

Yesterday I was trying to solve some other problem, following steps given on this page http://www.ivegotavirus.com/blog/2011/11/06/how-to-get-optimus-working-on-ubuntu-11-10-oneiric/

Soon after step 3) sudo apt-get install bumblebee, fan started working fine.

Is this related? Now fan works fine. I haven't finished the steps mentioned on the page. Just installed bumblebee, now fan is working normally.

I also keep ubuntu uptodate so not sure if that is also related. I am using 3.0.0-16-generic x86_64
