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.
