Nico Schottelius/ blog/ Getting the keyboard, touchpad and correct screen resolution working on the MacBook Air 4,2

Introduction

If you are running Linux on the MacBook Air 4,2 and have any of the following problems, this article is for you:

  • FN key not working / modifying keys
  • Touchpad not working in Multitouch mode
  • Resolution is 1280x800 instead of 1440x900

Touchpad and Keyboard

In Jiris for-next branch of the hid tree the keyboard and touchpad issues have been solved.

Screen resolution

Keith fixed the screen resolution issues in his tree that you can retrieve:

git clone -b fix-edp-vdd-power git://people.freedesktop.org/~keithp/linux

Getting both fixes

Until the changes are merged into Linus' tree, I've setup a tree that merged the two previous ones:

  • gitweb
  • git://git.schottelius.org/foreign/linux-keith-jiri-mba

I've used the config.gz from Archlinux as base for .config and added the new config options, which resulted in a working .config for the MacBook Air.
