Can it be both a fan / sensor / GPU problem? To restate the symptoms: - the hardware runs hot in Linux, the same hardware runs cool in OS X - the fan(s) do not run automatically when the machines get hot - the fan(s) can be controlled manually - the temperatures from /usr/bin/sensors on the notebook seem suspiciously low The kernels are - 3.1.0-999-generic #201111070407 SMP Mon Nov 7 09:08:05 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux - 3.1.0-2-generic #3-Ubuntu SMP Fri Oct 28 20:28:07 UTC 2011 i686 i686 i386 GNU/Linux Output from apport can be found in Launchpad: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881593 The notebook is a MacBookPro8,2 and the desktop is a Macmini3,1 How should I split the problem up and where should I pursue their resolution? /Lars
