Keyboard layouts for Macbook Pro under Ubuntu Linux

Modifying the following keyboardl ayouts:

English (Macintosh)
Russian (Macintosh)
Ukrainian (Macintosh)

Add the keyboard layout into the system

1.a Copy modified files

$ cd /path/to/the/mac-linuxxkb/
$ sudo cp us ru ua /usr/share/X11/xkb/symbols/

1.b Or edit the keyboard layout files

English (Macintosh)

Has the following problems:

Incorrect arrangement of the tilde and plusminus symbols;
Incorrect location of the sharp symbol;

Open the /usr/share/X11/xkb/symbols/us with root privileges, find the English (Macintosh) block and change the codes as:

...
key <TLDE> { [   section,  plusminus,       section,        plusminus ] };
key <LSGT> { [     grave, asciitilde,    dead_grave,        dead_horn ] };
key <AE03> { [         3, numbersign ] }; 
...

Russian (Macintosh)

Has no problems.

Ukrainian (Macintosh)

The keyboard layout is completely absent in the system.

Open the /usr/share/X11/xkb/symbols/ua with root privileges, find the Ukrainian (legacy) block and after this block, create a new block Ukrainian (Macintosh) as:

...
partial alphanumeric_keys
xkb_symbols "legacy" {

    name[Group1]= "Ukrainian (legacy)";
    ...
};

partial alphanumeric_keys
xkb_symbols "mac" {

    include "ua(legacy)"
    name[Group1]= "Ukrainian (Macintosh)";

    key <AC02> { [   Cyrillic_i,  Cyrillic_I  ] };
    key <AB05> { [  Ukrainian_i, Ukrainian_I  ] };

    key <LSGT> { [         less,     greater  ] };
    key <AE02> { [            2,    quotedbl  ] };
    key <AE03> { [            3,  numerosign  ] };
    key <AE04> { [            4,     percent  ] };
    key <AE05> { [            5,       colon  ] };
    key <AE06> { [            6,       comma  ] };
    key <AE07> { [            7,      period  ] };
    key <AE08> { [            8,   semicolon  ] };
    key <TLDE> { [ bracketright, bracketleft  ] };
    key <BKSL> { [ Ukrainian_ghe_with_upturn, Ukrainian_GHE_WITH_UPTURN ] };
};
...

2. Registrate the keyboard layout

The English (Macintosh) and the Russian (Macintosh) keyboard layouts already registered in the system. Now need to add a record about Ukrainian (Macintosh).

Open the /usr/share/X11/xkb/rules/xorg.lst with root privileges, find the homophonic ua: Ukrainian (homophonic) string, and add after this line: mac ua: Ukrainian (Macintosh):

...
legacy          ua: Ukrainian (legacy)
rstu            ua: Ukrainian (standard RSTU)
homophonic      ua: Ukrainian (homophonic)
mac             ua: Ukrainian (Macintosh)
extd            gb: English (UK, extended, with Win keys)
...

Open the /usr/share/X11/xkb/rules/evdev.xml with root privileges, find the Ukrainian block, and add Ukrainian (Macintosh) variant into variantList:

...
      <variantList>
        <variant>
          <configItem>
            <name>mac</name>
            <description>Ukrainian (Macintosh)</description>
          </configItem>
        </variant>
        ...
      </variantList>
...

The end

Reboot your system! Open keyboard settings and select layouts:

English (Macintosh)
Russian (Macintosh)
