iMac UK keyboard layouts incorrect or fail

Problem persists on Gutsy tribe 2.

A bug maintainer changed the sourcepackagename from None to xorg. However, I don't think the bug is xorg specific, because the problem also appears in virtual consoles. Some tweaking to the underlying way that the keymaps work is required.

Ok, lets try console-setup. Do you still have the problem in 7.10 or Hardy alpha3?

Currently, I am using Gutsy 7.10 (full version). Virtual console grave and tilde don't work correctly.

So now I install:
 console-common
 console-data
 console-setup
 console-tools

As root, I do:
 dpkg-reconfigure console-setup
with
 Keyboard model: Macintosh
 The origin of the keyboard: United Kingdom
 Keyboard layout: United Kingdom
 AltGr key replacement: No AltGr key
 Compose key: No compose key
 Encoding on the console: UTF-8
 Set of characters ... : Combine - Latin; ...
 Font for the console: Fixed
 Font size: 16
 Virtual consoles in use: /dev/tty[1-6]
It generates the output:
 * Saving console font and keymap for next boot...

Virtual console grave and tilde is still not working at this stage.
I reboot, but it doesn't help.
Next, as root, I type
 install-keymap /usr/share/keymaps/i386/qwerty/mac-usb-uk.kmap.gz
If I go to a virtual console, then the the grave and tilde work correctly.
Also, the the key below the Esc key works correctly, too (formerly, it
operated the grave and tilde, which was wrong). The £, $, @ and " keys
all seem to work properly, too, so that keymap is exactly what I'm looking
for.

I reboot again, but the keyboard layout reverts to the old one (i.e.
where the grave and tilde don't work properly).

This is still an ongoing problem with Hardy (full version).

Is there any way of telling what keymap I'm actually using?

In my .xession file, I have added the line
xmodmap ~/docs/uconfig/xmodmap

In ~/docs/uconfig/xmodmap I have added the lines
keycode 49 = section plusminus
keycode 94 = grave asciitilde
This fixes the keyboard for me. So there's something that you guys need to jig in order to get the keyboard working properly.

Here's my xorg.conf keyboard setting:
Section "InputDevice"
        Identifier "Generic Keyboard"
        Driver "kbd"
        Option "XkbRules" "xorg"
        Option "XkbModel" "pc105"
        Option "XkbLayout" "gb"
        Option "XkbVariant" "mac"
EndSection

BTW, the corresponding keys on the virtual consoles are also wrong - although they do not generate the same values.

I'd be grateful if there was some way that this bug report isn't automatically expired, as it's been an issue that's been ongoing for some time, and it's definitely a bug.

Mark, do you know if this is still a problem in any release past hardy?

Rolf, I seem to recall that Intrepid still had the problem. I'm using a regular Dell keyboard at the moment, and haven't got Jackalope currently installed. It's a bug that seems to have been ongoing for ages, and I've no reason to suppose that it's been fixed. When Koala comes along I can retest the keyboard. Until then, it would be best to keep this bug report open.

I can confirm this with Jaunty on a PowerPC iMac (/proc/cpuinfo: NewWorld 66 iMac FireWire, PowerMac2,2 740/750) with the Apple USB Keyboard (model number M2452). I've attached a photograph to avoid confusion.

There are two issues:

1. Mapping of the UK key-cap symbols for many of the non-alphabetical keys is incorrect in console and Xorg
2. Selecting Apple-specific layouts fails under Xorg.
3. There is no "#" symbol and no obvious alternate way to generate it - a big problem when trying to edit shell scripts

Closing due to age.
If a similar bug appears in 15.04 (development) please open a new report.

This still affects 12.04, 14.04 and beyond. In particular, Apple Bluetooth keyboard layouts (used with IBM-PC compatibles as well as Apple hardware), including the numeric keypad not operating in numeric mode and no obvious way to switch to it. "#" requires Right-alt+3, "~" and "|" keys reversed between Xorg and virtual terminals.
