I'm new with Ubuntu and I'm enjoying my experience with Ubuntu 11.10 on my Lenovo ideapad Y460. I'm dual booting Ubuntu with Windows 7 64 bit. It's great using Ubuntu, however I noticed that my laptop heats up rather quickly when I use Ubuntu. Does this have to do with drivers? I have Nvidia GT 425M graphics, but I don't know if this information is relevant. My fans are just not working right as they do in Windows 7. Did I miss installing something or what am I doing wrong?
