System Summary

SATA / AHCI Mode

Many SATA controllers have two modes of operation: IDE mode (using the ata_generic or the ata_piix kernel modules for example), and AHCI mode (using the ahci module). Apple determines the mode of operation on boot based on whether the system is booted in EFI mode or BIOS compatibility mode (see the whole section on EFI/BIOS for more detail).

When you use BIOS mode the SATA controller will be switched to IDE mode. If you want to set the controller in AHCI mode while using BIOS compatibility before the kernel boots up, you can do it using GRUB2. The reason why you might want to do this, is because the AHCI mode and module ensures better performance under load, and is generally more stable.

The fix is to just add a setpci call on your GRUB configuration. To be safe you can test it by going into command line mode in GRUB, and doing something like this:

> lspci
(check for the ID for IDE mode, in my case 8086:2828)
> setpci -d 8086:2828 90.b=40
> lspci
(The 2828 ID is now gone, replaced by 8086:2829, AHCI/SATA mode)

You can add this to your GRUB configuration, and avoid losing it on upgrades, by adding a script like this to /etc/grub.d/:

#!/bin/sh
set -e
## Enable SATA (AHCI) mode on macbook 3,1
echo "setpci -d 8086:2828 90.b=40"

Apple Keyboard

Configuration

You can set up the keyboard layout with this command:

$ sudo dpkg-reconfigure keyboard-configuration

This will change the config file /etc/default/keyboard into something like this:

XKBMODEL="apple_laptop"
XKBLAYOUT="us"
XKBVARIANT="mac"
XKBOPTIONS="terminate:ctrl_alt_bksp"

… or another example:

XKBMODEL="pc105"
XKBLAYOUT="fr"
XKBVARIANT="mac"
XKBOPTIONS="lv3:rwin_switch"

Default behaviour

'fn'+'Enter' -> Insert
'fn'+'Backspace' -> Delete
'fn'+'Up' -> PageUp
'fn'+'Down' -> PageDown
'fn'+'Left' -> Home
'fn'+'Right' -> End
'Clear' -> NumLock

Function key behaviour

The hid_apple module has a parameter called 'fnmode' to change the behaviour of the 'fn'-key

There's three settings for fnmode:

0 = disabled: Disable the 'fn' key. Pressing 'fn' has no effect
1 = fkeyslast: Enable the 'fn' key. Pressing 'F1-F12' keys will act as special keys. Pressing 'fn'+'F1-F12' will behave like 'F1-F12'.
2 = fkeysfirst: Enable the 'fn' key. Pressing 'F1-F12' keys will behave like the real 'F1-F12'. Pressing 'fn'+'F8' will act as the special key (play/pause in this case).

There's several ways to set this parameter:

using sysfs, for example:

$ echo 2 | sudo tee /sys/module/hid_apple/parameters/fnmode

as a module parameter (won't work if you compile hid_apple in your kernel):

$ echo options hid_apple fnmode=2 | sudo tee -a /etc/modprobe.d/hid_apple.conf 
$ sudo modprobe --dry-run hid_apple

if this throws no error you can

$ sudo update-initramfs -u

on the kernel command line: edit /etc/default/grub, and add the following to the GRUB_CMDLINE_LINUX_DEFAULT variable:
```
hid_apple.fnmode=2
```

Swapped keys on international keyboards

The hid_apple module also has a parameter called 'iso_layout'

0 means international layout, so on an 'English International' keyboard the '§±'-key will be top left, and the '`~'-key will be next to left shift
1 swaps it around

There's several ways to set this parameter:

using sysfs, for example:

$ echo 0 | sudo tee /sys/module/hid_apple/parameters/iso_layout

as a module parameter (won't work if you compile hid_apple in your kernel):

$ echo options hid_apple iso_layout=0 | sudo tee -a /etc/modprobe.d/hid_apple.conf 
$ sudo modprobe --dry-run hid_apple

if this throws no error you can

$ sudo update-initramfs -u

on the kernel command line: edit /etc/default/grub, and add the following to the GRUB_CMDLINE_LINUX_DEFAULT variable:
```
hid_apple.iso_layout=0
```
