Fn key doesn't work in raring on MacBook Air 6,2

[Linus G Thiel]

After installing Raring on my new MacBook Air 6,2, the Fn key didn't work -- I couldn't use the media keys, regardless of "fnmode", neither backspace, page up/down, etc.

I found bug #207127 and I figured it was something like that, and it turns out that the keyboard has a new device id. I added it to the usbhid driver and after that it works.

Please see the attached patch.

Note: I just followed the pattern of naming the keyboard APPLE_WELLSPRING something, without knowing what that means.

I guess this could be solved with the quirks parameter to usbhid, like in this comment [1], but I couldn't figure out the correct bitmask to set as quirks.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10-saucy/

[Joseph Salisbury (jsalisbury)]

Sorry, Linus I see you attached a patch, so no need to test the upstream kernel.

Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

[Linus G Thiel (yesbabyyes)]

I have corresponded with Jiri Kosina, the maintainer, who let me know that Henrik Rydberg beat me to the punch. So it's apparently queued in input.git#for-linus already.

I'll try to keep an eye on it.

[Linus G Thiel (yesbabyyes)]

The patch is available here:

https://github.com/torvalds/linux/commit/9d9a04ee758b4c1fcc7586d065cdde7a7607e156

[Joseph Salisbury (jsalisbury)]

Thanks for the pointer, Linus.

Commit 9d9a04ee is in mainline as of v3.11-rc1. It was also cc'd to upstream stable, so it will make it's way into all the stable kernel versions, including Raring.

I'll build a test kernel for you with this patch and post a link shortly. If it fixes this bug, I can submit an SRU request to have this included in Raring until the fix makes its way down through stable updates.

[Joseph Salisbury (jsalisbury)]

I built a Raring test kernel with commit 9d9a04ee applied. The kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1196730/

Can you test this kernel and post back if it resolves this bug? Please note, you will need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

[Julian Wiedmann (jwiedmann)]

Should be fixed in current -proposed (3.8.0-28.41) with

HID: apple: Add support for the 2013 Macbook Air
Input: bcm5974 - add support for the 2013 MacBook Air

[Julian Wiedmann (jwiedmann)]

Linus G Thiel,

could you please test the latest kernel in -updates (3.8.0-29.42) and see if this bug is fixed? Thanks.

[Miek Gieben (miek)]

(I also own a Macbook air 2013 model)

I tested this kernel. Needed to manually load the hid-apple, didn't work after that.
After login in again in X, neither fn-F1 or F1 set the brightness (I just loads the terminal help program).

[Miek Gieben (miek)]

Note: this is on a Macbook Air 2013 6,1 Model, lsusb lists:

[Miek Gieben (miek)]

Note this is about to be fixed, see https://bugzilla.kernel.org/show_bug.cgi?id=60181, 0x0290 should be added too to that patch

[Julian Wiedmann (jwiedmann)]

Miek,

Let's please use the bug you already filed (bug 1213770) to track the 0x0290.

[Linus G Thiel (yesbabyyes)]

Yes, I can confirm it's fixed in kernel 3.8.0-29.42.

Sorry for the delay.

[Linus G Thiel (yesbabyyes)]

Actually, it's not quite fixed. The patch that went in for this had the device ids wrong, I think. I am in touch with Henrik Rydberg about this. It kind of works for me now, but the <> and the §° buttons are switched, which is because I don't get the ISO flag set.

I think it will get sorted upstream eventually, but right now it's just a little bit off.
