macbook keyboard layout maps the tilde key to something else

[Krister]

1. install ubuntu on Macbook Air 6,2
2. press the key with the tilde ('~') written on it.
3. see that is prints '§' instead.

This is particularly annoying since the way to switch between windows uses the tilde.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 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.

[Krister (thekswenson)]

the bug still exists in 3.12.0-031200rc7-generic

[Launchpad Janitor (janitor)]

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[Krister (thekswenson)]

Expired. The bug still exists though.

[nfsd (in4mer+launchpad)]

I too experience this bug on a late-2013 MBA, booting a freshly installed UEFI boot of 13.10.

I'm confirming that this bug exists as described.

[Yuan Chao (yuanchao)]

I've got the same problem on 13.10 on macbook air 6,2 (2013). Both standard US and Machintosh layout maps "`~" into other characters.

[Yuan Chao (yuanchao)]

According to this bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1025041

"According to an upstream bug report, the ANSI/ISO detection of the keyboard is incorrect."

there's a walk-around:

       echo 0 > /sys/module/hid_apple/parameters/iso_layout

I can confirm that this fixes the problem on macbook air 6,2 (2013) with ubuntu 13.10.

[Daryl Tucker (daryltucker)]

The workaround posted by Yaun worked for me on my 13.10 installation on my Macbook Air 6,2 (2013). Thank you very much.

>> sudo su -
>> echo 0 > /sys/module/hid_apple/parameters/iso_layout

[Krister (thekswenson)]

it works for me as well.

[Dan Herman (dan-herman)]

This workaround works for me too on MacBook Air 6,2 using Ubuntu 13.10

Thanks!

[Daryl Tucker (daryltucker)]

To make this fix persistant, just add the line to your **/etc/rc.local**

>> echo 0 > /sys/module/hid_apple/parameters/iso_layout

[hawodi (hawodi-gmail)]

Thanks so much ~yuanchao! Your solution works for me.

[Chris Cowan (agentme49)]

I ran into this problem on a fresh install of Ubuntu 15.04 on a Macbook Air. The "echo 0 > /sys/module/hid_apple/parameters/iso_layout" workaround worked for me.

[jonathan chetwynd (peepo-com)]

workaround wfm mac mini 14.04 3.13.0-68

[Thiago Martins (martinx)]

Still present on Xenial 16.04.

Workaround is good.

[FGM (fgm)]

Workaround does not work on Xenial 16.04 in a Fusion 8.1.1 box: sys/module/hid_apple does not exist and can not be created, even with sudo.

[Yuan Chao (yuanchao)]

Workaround is still needed and works on Xenial 16.04 for my MBA 6,2 (2013).

[azrobbo (azrobbo)]

I can confirm this bug still exists and the workaround still works for Xenial 16.04 on my MBA 6,2

(Posted so the entry won't expire.)

Will the bug ever be fixed?

[Gunnar Hjalmarsson (gunnarhj)]

There is an XKB option solution to this issue on Debian/Ubuntu:

setxkbmap -option apple:badmap

[azrobbo (azrobbo)]

I can confirm this bug still exists in Zesty 17.04 on my MBA 6,2

This workaround still works:
echo 0 | sudo tee /sys/module/hid_apple/parameters/iso_layout

[Kai-Heng Feng (kaihengfeng)]

Please try latest mainline kernel (v4.13-rc3)

I think this commit solves the issue:
