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.enable_fbc=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 and, of course xf86-video-intel.
If Xorg refuses to start with a "no screens found" message. You have two options, tell Grub2 to turn off the Radeon card and turn on the Intel card during boot; or force the EFI to use the integrated card instead.
Force EFI to use integrated
If you want to force the EFI to use the integrated graphics card, then check the following topic: force 2011 macbook to use integrated card. You may need to append radeon.modeset=0 to your kernel command line so that linux does not attempt to use it:
radeon.modeset=0
Use grub2
If you want to tell grub2 then 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 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.
Wireless network
See Broadcom wireless for b43 installation and usage.
Keyboard and touchPad
Keyboard
Default F1 key represents XF86MonBrightnessDown, if you want it represents to F1. Set fnmode=2
parameters to hid_apple module.
See Kernel modules#Configuration[broken link: invalid section] for instruction.
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.
There are two drivers to provide features to the touchpad (including right and middle click): mtrack which is reported to work well and Synaptics which provides more features but might require some tuning.
mtrack:
Mtrack is available 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
synaptics:
See Touchpad Synaptics#Installation for synaptics installation and configuration instructions.
#list all possible configurable parameters. synclient #To change a value for a command use `synclient command=X` #Example: synclient HorizTwoFingerScroll=1
After you have successfully tried and tested your options through synclient, you can make these changes permanent by adding them to /etc/X11/xorg.conf.d/50-synaptics.conf
Video and 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/local/bin/macbackl
and mark it as executable:
# chown +x /usr/bin/macbackl
For usage, run:
$ macbackl --help
/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[broken link: archived in aur-mirror] and reboot system.
# echo 34839 > /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 and hibernate
Consulte Suspend and hibernate.
8,1
For s2ram install uswsusp-gitAUR 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). The solution is creating /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
Others that works-out-of-the-box
- Sensors
Troubleshooting
Broken integrated GPU
The 8.2 macbook pro models with integrated graphics card have a manufacturing issue that causes the lead-free solder of the GPU to crack, inhibiting its ability to function. The problem begins by seeing red lines on the monitor and then failing to boot OS X. Apple issued a repair program, but the odds are that your GPU will die again soon.
It is still possible to boot linux using the outb 0x750 lines in grub2 as described above, however this is a nuisance because it may be impossible to read the monitor when the problem is severe, making installation impossible. In addition, you may also wish to use another boot loader other than GRUB.
It is possible to fix the problem by forcing the EFI to use the integrated graphics card.
If you want to force the EFI to use the integrated graphics card, then check the following topic: force 2011 macbook to use integrated card. You may need to append radeon.modeset=0 to your kernel command line so that linux does not attempt to use it:
radeon.modeset=0
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.
You have two options, use grub to disable the discrete GPU or disable the discrete GPU in the EFI.
' use grub '
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.
' Force EFI to use integrated '
If you want to force the EFI to use the integrated graphics card, then check the following topic: force 2011 macbook to use integrated card. You may need to append radeon.modeset=0 to your kernel command line so that linux does not attempt to use it:
radeon.modeset=0
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
