Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I recently installed ubuntu 10.10 onto my Macbook Pro 6,2 unibody. I've got everything setup (not my first time), except on startup the fan goes crazy. I choose linux from rEFIt, and after GRUB the fan turns up to what I think is the highest speed.

The computer definitely is not overheating. It doesn't do this when booting Mac OS X.

  • Macbook Pro 6,2 Unibody (15")
  • Ubuntu
  • 10.10 kernel 2.6.35-28 generic
  • Mactel PPA (pommed, etc.)

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

I suspect people will need more information to help you out, unless they have exactly the same hardware. a good place to start would be to try and install lm-sensors, and post the output from the 'sensors' command while your fan is blitzing. that'll show what temperature your computer thinks it is at, and what control it has over the fans. –  thomas michael wallace May 29 '11 at 17:36

I can't answer this problem specifically, but I can say that I do not have this problem with 11.04 on my Macbook Pro 6,2 With 11.04 I needed to load the module coretemp to get the fans working. (Edit /etc/modules and add coretemp and reboot). Running sensors shows reasonable temperatures and the fans are generally quiet, but slowly speedup when necessary.

Sounds like you might need to reset the SMC (System Management Controller) - see this Apple Knowledgebase article for the full details -
