On my MacBook Air MID 2012 I use Ubuntu since 12.04. After installing Ubuntu I had to install the "macfanctld" package (incl. configuration) to get the fan control of my MBA working. If not, the fan (exhaust) stays always on the minimum = 2000 rpm (maximum = 6000 rpm).
The ppa has only an update for (raring) Ubuntu 13.04. I asked the author of the package a view months ago if there is an 13.10 update planned, but I did not received an answer.
Here is the link to the ppa: https://launchpad.net/~mactel-support/+archive/ppa?field.series_filter=raring : It contains only a package for raring and not for saucy.
I installed the 13.04 package on my Ubuntu 13.10 but I am not sure if I should install the "old" package??
On 13.10 I installed it with the following commands:
sudo tee -a /etc/apt/sources.list <<-EOF
deb http://ppa.launchpad.net/mactel-support/ppa/ubuntu raring main
deb-src http://ppa.launchpad.net/mactel-support/ppa/ubuntu raring main
EOF
sudo apt-get install macfanctld
Here is the link to the full script for 12.10: http://www.maketecheasier.com/install-ubuntu-12-10-in-macbook-air/ (see #6)
Is this package not necessary any more for Ubuntu 13.04 and higher ??
