EFI Boot
Consult UEFI
radeon driver which only loads properly on Macs in BIOS emulation mode, problem description and possible solution here.
8,1
Tested on macbook pro 8.1 . Forum thread: [1]
Add following to Kernel Parameters.
i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 usbcore.autosuspend=1 h
8,2 and 8,3
While using EFI Boot, you will find
radeon 0000:01:00.0: >Invalid ROM contents i915 0000:00:02.0: Invalid ROM contents
Which means you need disable KMS for amd and intel card. Add following to Kernel Parameters.
i915.modeset=0 radeon.modeset=0
newer versions of the Xorg Intel/i915 driver require KMS to work; without it the X server will fallback to framebuffer mode, with poor performance. The underlying issue is that the Intel KMS driver selects the wrong video output; to fix this try the following settings (tested on an 8,3/17" MBP):
radeon.modeset=0 i915.modeset=1 i915.lvds_channel_mode=2
This should give you Intel graphics output. Note that this requires kernel 3.5rc1 or higher; use linux-mainline from Aur if necessary. See this bug for more details.
If you don't have KMS for intel driver, you need install 'xf86-video-fbdev'
# pacman -S xf86-video-intel and xf86-video-fbdev
If Xorg refuses to start with a "no screens found" message you may have to tell Grub2 to turn off the Radeon card and turn on the Intel card during boot. Edit /etc/grub.d/00_header and add the "outb" lines immediately after "set gfxmode=" (Tested on an 8,2 MBP):
...
set gfxmode=${GRUB_GFXMODE}
outb 0x728 1
outb 0x710 2
outb 0x740 2
outb 0x750 0
load video
...
Then regenerate your grub.cfg:
# grub-mkconfig -o /boot/grub/grub.cfg
Using rEFInd and Kernel EFISTUB
Install rEFInd
Consult Installing rEFInd
Boot into Mac OS X
# mkdir -p /efi/refind # cp -r refind/* /efi/refind/ # rm /efi/refind/refind_ia32.efi # mv /efi/refind/refind.conf-sample /efi/refind/refind.conf and adjust it # bless --setBoot --folder /efi/refind --file /efi/refind/refind_x64.efi
Setting up EFISTUB
Follow UEFI Bootloaders#Linux Kernel EFISTUB
Add Kernel MODULES
Without this, you will get 'root fs not found' error.
Edit /etc/mkinitcpio.conf
MODULES="..ahci libahci.."
Then re-generate the boot img:
# mkinitcpio -p linux
BIOS Boot
Boot into BIOS emulation mode. AMD card works, but intel card doesn't.
Use refind to load grub-legacy.
Network
Wireless:
Install b43-firmwareAUR package from the AUR.
Unload b43 and bcma modules and load b43 module
# rmmod b43 bcma # modprobe b43
That's it. The wireless should work now.
Ethernet: works out-of-the-box
Bluetooth: Unkown
Keyboard & TouchPad
Keyboard:
default F1 key represents XF86MonBrightnessDown, if you want it represents to F1.
echo 2 > /sys/module/hid_apple/parameters/fnmode # value 1: F1 is XF86MonBrightnessDown # value 2: F1 is F1, Fn + F1 is XF86MonBrightnessDown.
and put that into /etc/rc.local
Touchpad:
Two finger scrolling and left-click works out of the box. Unfortunately the right-click is not functional.
14/09/2012 : right click (2 fingers) and middle click (3 fingers) works out of the box with KDE.
To enable most of the multitouch touchpad features (even right and middle clik) use mtrack, which is avaible in AUR. The configuration is done via the /etc/X11/xorg.conf.d/10-mtrack.conf file. Check if the mtrack module is properly loaded in the /var/log/Xorg.0.log file. Sometimes xorg loads other drivers before, like eg. synpatics, and the mtrack driver is not used at all.
For an MBP 8,3 I needed to use the following config (in /etc/X11/xorg.conf.d/10-mtrack.conf) to stop it picking up other input devices by mistake:
Section "InputClass" Identifier "Multitouch Touchpad" Driver "mtrack" MatchDevicePath "/dev/input/event*" MatchProduct "bcm5974" MatchIsTouchpad "true" EndSection
Video & Screen
13-inch
Intel HD Graphics 3000: works with xf86-video-intel
Adjust Brightness: works with xorg-xbacklight For example:
xbacklight -inc 7 # increase brightness xbacklight -dec 7 # decrease brightness
or you can use a simple bash script that provides screen and keyboard backlight management by simple cli (-d for display / -k for keyboard)
#!/bin/bash
case $1 in
-d|--display)
if [ "$2" != "0" ]
then
echo "$[(($2 * 4882) / 100) % 4883]" > /sys/class/backlight/intel_backlight/brightness
fi;;
-k|--keyboard)
echo "$[(($2 * 255) / 100) % 256]" > /sys/class/leds/smc\:\:kbd_backlight/brightness;;
-h|--help)
echo -e "MacBook 8.1 brightness helper\n\t-d\tset display brightness (0-100%)\n\t-k\tset keyboard brightness (0-100%)\n";;
*)
echo -e "Unknown option try -h or --help";;
esac
save it in
/usr/bin/macbackl
mark executable
# chown +x /usr/bin/macbackl
for usage, run
# macbackl --help
NOTE: you must be root to edit the files in /sys/class/* but if you want you can chown "/sys/class/leds/smc\:\:kbd_backlight/brightness" and "/sys/class/backlight/intel_backlight/brightness"
15-inch and 17-inch
AMD Radeon HD 6490M: Unknown
AMD Radeon HD 6750M and 6770M: works with xf86-video-ati
Adjust Brightness: install AUR package apple-bl-gmuxAUR and reboot system.
$ echo 34839 | sudo tee /sys/class/backlight/gmux_backlight/brightness
Sound
8,1 and 8,2
$ alsamixer # unmute 'Front Speaker' and 'Surround Speaker'
8,3
Using PulseAudio sound works out of the box. However some applications (e.g. Vlc) have intermittent crackling; appending 'tsched=0' to 'module-udev-detect' in /etc/pulse/default.pa fixes this.
Suspend & Hibernate
Consulte Suspend and Hibernate.
8,1
For s2ram install uswsusp-git and add to file /etc/pm/config.d/module following content:
SUSPEND_MODULES="bcma b43" SLEEP_MODULE=uswsusp
Without this, system hangs after the machine wakes up and tries to reconnect to the wireless network.
8,2
BIOS Boot: using linux >= 3.6.2, supend and resume works out-of-the-box.
EFI Boot: resume may not work.
8,3
Supend and resume work out of the box, including wireless reconnection.
HFS+
HFS is mounted as Read-Only. By turning journaling off in OS X, the HFS+ file system will be read/write under Linux.
Bluetooth
I had problems pairing devices, nothing was detected with
hcitool scan
There seems to be a conflict between the bluetooth module and the b43 one (wifi), as written in this blog post. The solution is to do the following:
# rmmod b43
pair your bluetooth device
# modprobe b43
Alternative solution
Create /etc/modprobe.d/b43.conf with the following content:
options b43 btcoex=0
Webcam
In order to use your webcam you need to have permission to use /dev/video0.
# gpasswd -a <username> video
Test to see if it works
$ mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -fps 15 -vf screenshot
With linux-mainline
As noted elsewhere in this document, some MBP features work best (or only) with the latest kernel; the usual way to install this is using the linux-mainline AUR package. However, as of 3.6.rc3 the config for linux-mainline disables webcam support (due to changed defaults in kernel). This patch to the x86_64 config fixes this issue.

Troubleshooting
Grub2-EFI boot: Intel invalid ROM contents
If you see this error on boot and notice the screen output seemingly frozen, you need to disable KMS.
Append the following to your /etc/grub/defaults LINUX line:
i915.modeset=0 radeon.modeset=0
However, newer versions of the Xorg Intel/i915 driver require KMS to work; without it the X server will fallback to framebuffer mode, with poor performance. The underlying issue is that the Intel KMS driver selects the wrong video output; to fix this try the following settings (tested on an 8,3/17" MBP):
radeon.modeset=0 i915.modeset=1 i915.lvds_channel_mode=2
This should give you Intel graphics output. Note that this requires kernel 3.5rc1 or higher; use linux-mainline from Aur if necessary. See this bug for more details.
You may find you need to enable the Intel device; if using Grub, the following should enable it at boot time:
set gfxpayload=keep # Switch gmux to IGD outb 0x728 1 outb 0x710 2 outb 0x740 2
Alternatively, if you have OS X available you can use gfxCardStatus to switch to the Intel device before booting into Linux.
Grub2-EFI boot: root fs not found
On boot, grub2-efi may complain that no root fs is found. This is due to the ahci modules being improperly loaded.
chroot into the installed Arch system. Then edit the /etc/mkinitcpio.conf MODULES array:
MODULES="..ahci libahci.."
Then re-generate the boot img:
mkinitcpio -p linux
