Apple USB BCM5974 (Macbook Air and Penryn Macbook Pro) multitouch driver
This driver adds support for the multitouch trackpad on the new
Apple Macbook Air and Macbook Pro Penryn laptops. It replaces the
appletouch driver on those computers, and integrates well with the
synaptics driver of the Xorg system.
Known to work on Macbook Air, Macbook Pro Penryn and the new Unibody
Macbook 5 and Macbook Pro 5.
Support for the latest Macbooks is not upstream yet, but available in the mactel PPA.
Make sure you have these lines in /etc/apt/sources.list:
When changing /etc/apt/sources.list, one needs to update:
deb http://ppa.launchpad.net/mactel-support/ubuntu intrepid main
deb-src http://ppa.launchpad.net/mactel-support/ubuntu intrepid main
With the mactel PPA in place, install the bcm5974-dkms package
sudo apt-get update
sudo apt-get install bcm5974-dkms
