the bug still exists in 3.12.0-031200rc7-generic

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

Expired. The bug still exists though.

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.

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.

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.

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

it works for me as well.

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

Thanks!

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

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

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

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.

workaround wfm mac mini 14.04 3.13.0-68

Still present on Xenial 16.04.

Workaround is good.

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.

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

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?

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

setxkbmap -option apple:badmap

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

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

I think this commit solves the issue:
