Bug Description

Binary package hint: linux-image-2.6-amd64-generic

fn key is required on apple keyboards to do common functions (delete, pageup/down, home/end, volume, etc). The apple aluminum keyboard and new macbook3,1 ("Santa Rosa") are both affected.

Attached is a patch from the mactel-linux-devel list by Martin Szulecki <email address hidden> that adds the aluminum keyboard. I have modified the patch to include the macbok3,1 keyboard as well as additional keycodes that were present on "powerbook" keyboards (delete, pgup/down, home/end).

This patch has been tested on a macbook 3,1 by myself on an amd64 kernel.

I can confirm that this patch works, at least for the fn key.

I tried installing this patch on both i386 and amd64. This patch works for me on both for the fn key but the brightness controls aren't working (with or without the patch/with or without pommed v1.11).

udpate: the patch seems to have changed the functionality of my ` key. Whenever I press the ` key, I get the character <. Whenever I press <shift> to along with ` to get ~, I get >.
Also the F5 and F6 keys are producing ~ character in the terminal.

Chris Irwin (chrisirwin) wrote :

sidgalt, what kind of keyboard do you have? can you please attach the output of `lsusb` to this ticket?

The brightness keys send the correct key codes, but being detected by HAL requires the patch in bug #163725. Having HAL do something when these keys are detected depends on bug #162560.

Attached is an updated patch that adds IDs for several keyboards. Included are the ANSI, ISO, and JIS variants of the macbook3,1 keyboard, and both the wired and wireless Apple Aluminum keyboards ("2007" variant according to apple's kext). It also adds a fix needed for ISO keyboards as two keycodes were reversed. The code for handling this already existed for powerbook iso keyboards.

Chris Irwin (chrisirwin) wrote :

Note that the git packages referenced are lacking the wireless aluminum + macbook3,1 IDs

Mario Limonciello (superm1) wrote :


Additionally, the patches posted here don't seem to work with my wireless variant. Note that they are patching the hid-quirk's in the usb* devices only. Shouldn't they be applied elsewhere for the wireless version?

Chris Irwin (chrisirwin) wrote :


I had thought that the wireless devices would still go through the usbhid as there seems to be no other applicable quirks file. I did not have an apple bluetooth keyboard to test, and it never occurred to me that it may not.

Do you know what driver handles your keyboard then?

I want to say it's just directly handled by the normal input driver interface
for the kernel.

The only relevant things that I'll see crop up are these in dmesg:

[ 44.100775] input: Apple Computer, Inc. Mighty Mouse as /class/input/input12
[ 45.108663] input: Apple Inc. Keyboard as /class/input/input14

Obviously neither of those ends up loading usbhid, usbkbd, or usbmouse.

Lots of bluetooth modules begin to load too, but its hard to determine if they
were intended for usage by the devices or because of the usb bluetooth receiver.

Also, I do have an additional hald process running for this device, and a
bluetooth input service running

107 29123 0.0 0.0 2164 900 ? S 06:44 0:00
hald-addon-keyboard: listening on /dev/input/event7
root 6021 0.0 0.0 2772 1080 ? S Dec11 0:00

So with all that being said, i'm pretty confused myself as to who is actually
responsible for the fact that the keyboard works as much as it does :)

After doing some research on this topic I found the following patch, which at first does not work for me; however, after doing some further research I realised that "hidd" is showing 05ac:022d for my keyboard (perhaps a new version of the keyboard?) so I adjusted the address in the patch and now everthing is working fine ;-)


Mario Limonciello (superm1) wrote :

Well the more interesting part is that it is showing the same revision as the poster for my keyboard.

00:1B:63:FC:42:88 Apple Wireless Keyboard [05ac:022c] connected.

Where did you come across that post? According to:;a=blob;h=4bbacddeb49d4d4425177cf972b921bd195ec92f;hb=decbedde11cdda33533828757df87494b7ab1961;f=net/bluetooth/hidp/core.c
It appears that this hasn't been added to 2.6.24 even yet.

I'll do a test build of the module for 2.6.22 (which i'm still on)

Mario Limonciello (superm1) wrote :

Indeed that patch works perfectly for me on my aluminum wireless keyboard. (05ac:022c)

Mario Limonciello (superm1) wrote :

Well scratch the *perfectly*, it works well enough to re-enable the fn key, but all the mappings for the fX (f1 f2 f3 etc) keys are thrown off. Additionally the fn lock is on at all times, and turned off when i hold it down.

Chris Irwin (chrisirwin) wrote :


You should still be able to set /sys/module/hid/parameters/pb_fnmode to 2 and switch the fn key.

You would still need the patch included for the other keyboards to get the proper function mappings. however, There may be some other changes required to get those IDs to use the new mappings.

keans (keans) wrote :

I am glad it is working. I found this patch just by coincidence by googling for the apple aluminum keyboard...

If you see the first posts, this patch seems to be published a while ago in this newsgroup gmane.linux.bluez.devel
However, I have neither a clue how long it will take to go into the kernel nor if it ever will. Nonethesless, the question still is how many revision there are for this keyboard... Furthermore, for the fn-problem you could give pommed a try, which originally should help with the apple laptops hotkeys handling (I have not try it myselft until now)

is there any change this patch will eventually end in the HID tree? looks quite harmless to add a few ID and quirks

Hi Guys,

I looks like there are some patches in the upstream mainline kernel that may help resolve this bug. They appear to have gone in upstream after the 2.6.24 release which explains why they didn't make it into the Hardy kernel by default. I'm adding the upstream git commit id's for the kernel team to reference. Thanks.

Kernel 2.6.24-12.18 works nicely for me on a MacBook 4.1. I do see the same "problem" as Mario though that one needs to press fn to get at the fx keys rather than the special symbols. (So for example to press alt-f4 one now needs to press 3 keys simultaneous) As described by Chris, I can fix it by setting /sys/module/hid/parameters/pb_fnmode to 2. However at least to me, this logic seems inverted and so I was wondering if the default could be changed?

This fix doesn't work for my wireless aluminum keyboard unfortunately. I'm guessing it's just missing a vendor id or product id for it, but I haven't investigated closely.

this seems to have caused a regression that messes up the numlock/fn keys, and (in my case at least) the F1/F2/F3/F* keys too. See bug #201887.

Any thoughts?

The fix introduced for this bug seems to include several regressions for a lot of people. See Bug #201711, Bug #201887 and Bug #214786.

Generally it seems like a wrong solution to make all this peculiar keyboard mapping in kernel space and introduce kernel module parameters (pb_fnmode) for user customization. This Apple specific keyboard handling fills a significant portion of the HID module and even includes locale specific mapping! We already have keyboard layout handling several places in user space and also have the Keyboard Shortcut application to make special shortcuts for media keys. It seems more logical that the fn key should be treated as just another modifier key for general use. It might even make it possible to map it as an insert key which is missing from the keyboard and would normally be in its place.

Why is all this done in kernel space?

Petar Forai (pfo) wrote :

I experience the same kind of regression, F{1,2,3,4} keys are only working properly when pressed in conjunction with Fn, ie Fn + F1 = F1.

there are probably different versions of the keyboard out there... isn't possible to include both???

By the way, can anyone tell me why:

I included a patch for the current ubuntu kernel 2.6.24 from Hardy, so that it also activates fn key for Apple bluetooth alu keyboards, that identify as "hidd" 05ac:022d (and not only for 05ac:022c as tested by kernel 2.6.24). I tested the patch with my keyboard, that identifies with "hidd" 05ac:022d and it seems ok.

Hopefully that can be included in future versions.

UPDATE: A newly purchased (11/12/09) Apple Blueetooth Keyboard is having the same problem on kernel!

I guess they have changed the hex id (from 022d to 0239) of the keyboard, so the patch doesn't know to enable the FN key on this keyboard?

$ hidd --show
60:FB:42:00:5A:CD Apple Wireless Keyboard [05ac:0239] connected

Other than the FN key being nonexistant, this little Apple keyboard works just fine and has a better key feel than their older models.

I tried looking in the source files in net/bluetooth/hidp/core.c to see if I can backport one of the patches from above but the file drastically changed from the previous patches.

It has solution. Works well for Apple Wireless Keyboard [05ac:023a] - the only difference is product id.

It's hard to believe that a new keyboard model out of a manufacturer would require recompiling the kernel? Linus ought to be ashamed: the hex id for the specific keyboard model is hard-coded in the kernel source code?

True: it's actually a keyboard-handler loadable module, but still you seem to need the whole kernel source just to recompile that module...?
