如何添加新的键盘布局（自定义键盘布局定义）

772

我想复制一个键盘布局/usr/share/X11/xkb/symbols/并更改它，然后从中生成一个新布局。

如何添加新的键盘布局（例如命名为“mylayout”）？

更新#1：

我更改以添加新布局的文件：

/usr/share/X11/xkb/symbols/irwinxp（最初与相同ir）：

但是现在，随着这些变化，新的Persian-WinXP布局不服从irwinxp并被irwinxp忽略了。而是ir控制Persian-WinXP.

更新#2：

Unity 对我的新布局有问题。新布局图标是深色的。但效果很好。

注意：我使用的是 Ubuntu 14.04。

创建自定义键盘布局

For example, I'm looking to add a new modified English (international AltGr dead keys) US layout with swapped r,R & t,T. I will name it XY swapped:RT English (international AltGr dead keys).

Create new symbols file:

sudo nano /usr/share/X11/xkb/symbols/xy

 default  partial alphanumeric_keys
 xkb_symbols "basic" {

    name[Group1]= "XY swapped:RT English (international AltGr dead keys)";

    include "us(altgr-intl)"

 // my custom changes:

    key <AD04> { [        t, T,           ediaeresis,   Ediaeresis      ] };
    key <AD05> { [        r, R,           thorn,        THORN           ] };


    include "level3(ralt_switch)"
 };

include "us(altgr-intl)" means it inherits all key from that layout only key overridden here.

You may use Keyboard Layout Editor which is a GUI program that helps create or edit XKB keyboard layouts. Thanks to @Glutanimate

Add the new layout declaration to /usr/share/X11/xkb/rules/evdev.xml (copy & modify us layout section)

Reference: Make new variant keyboard layout available in Settings?

sudo gedit /usr/share/X11/xkb/rules/evdev.xml

 ...
 <layout>
   <configItem>
     <name>xy</name>

     <shortDescription>en</shortDescription>
     <description>XY swapped:RT English (international AltGr dead keys)</description>
     <languageList>
              <iso639Id>eng</iso639Id>
              <iso639Id>fra</iso639Id>
              <iso639Id>ger</iso639Id>
     </languageList>
   </configItem>
   <variantList>
   </variantList>
 </layout>
 ...

Delete xkb cache.
```
 sudo rm /var/lib/xkb/*.xkm
```
Notes:

To load changes to the layouts menu simply restart gnome-keyboard-preferences; relaunching the window manager should not be necessary.

There is a change in Ubuntu version 13.10 which causes the keyboard settings cache to not refresh after files in "/usr/share/X11/xkb/symbols" are modified. It looks like changes just don't get applied. To force the cache refreshing a one should delete *.xkm files from "/var/lib/xkb".

^{Reference: Howto: Custom keyboard layout definitions}

or
```
 sudo dpkg-reconfigure xkb-data
```
^{Reference: Why did 13.10 break my custom keyboard layout?}

(Update #1 wrong parent layout) You have modified xkb_symbols "pes_part_basic" which is in irwinxp file: that's ok.

but xkb_symbols "pes" in irwinxp file still:
```
  include "ir(pes_part_basic)"
```
which should be:
```
  include "irwinxp(pes_part_basic)"
```

(Update #2 custom icon) If <shortDescription>en</shortDescription> changed to <shortDescription>xy</shortDescription>. So the new layout will distinct from En and it will appear as Xy.

Most probably there will be no icon for it in ubuntu-mono. Then the indicator will dynamically generate new one which may not follow current theme.

Copy any layout icons for dark/light mono themes:

 sudo cp /usr/share/icons/ubuntu-mono-dark/status/22/indicator-keyboard-En.svg /usr/share/icons/ubuntu-mono-dark/status/22/indicator-keyboard-Xy.svg
 sudo cp /usr/share/icons/ubuntu-mono-light/status/22/indicator-keyboard-En.svg /usr/share/icons/ubuntu-mono-light/status/22/indicator-keyboard-Xy.svg

SVG files are just XML. Open then for editing and change text value from En to Xy:

 sudo nano /usr/share/icons/ubuntu-mono-dark/status/22/indicator-keyboard-Xy.svg
 sudo nano /usr/share/icons/ubuntu-mono-light/status/22/indicator-keyboard-Xy.svg

Example:

 <?xml version="1.0" encoding="UTF-8" standalone="no"?>
 <svg width="22" xmlns="http://www.w3.org/2000/svg" version="1.1" height="22">
  <defs>
   <mask id="m">
    <rect y="0" x="0" style="fill:#fff" height="22" width="22"/>
    <text y="15.5" x="5" style="font-size:12;font-family:Ubuntu;font-weight:500;fill:black">Xy</text>
   </mask>
  </defs>
  <rect style="fill:#dfdbd2" mask="url(#m)" rx="2" height="20" width="20" y="1" x="1"/>
 </svg>

Update theme cache:

 sudo update-icon-caches /usr/share/icons/ubuntu-mono-*/

How to modify a keyboard layout in Linux (thanks to @Rmano)
Building an XKB Keyboard (thanks to @Glutanimate)

sxc731 · Answer 2 · 2022-02-12T09:30:22+08:00

I've been using variations of the above answer for a number of years but things started to break with newer versions of Ubuntu and possibly due to the switchover to Wayland so I looked for another way.

It appears a more convenient and cleaner (since it's all in userspace) way of specifying keyboard layout customisations has been introduced. This has been tested on 22.04 LTS and 21.10 under GNOME/Wayland.

Here's an example that remaps the PrtSc ("print screen") key as the "menu" key. I find this useful on my ThinkPad keyboard, as it has this less useful (IMHO) former key in lieu of the latter.

mkdir -p ~/.config/xkb/{symbols,rules}
cd ~/.config/xkb
cat > rules/evdev << EOF
! option = symbols
  custom:prtscmenu = +custom(prtscmenu)

! include %S/evdev
EOF
cat > symbols/custom << EOF
partial modifier_keys
xkb_symbols "prtscmenu" {
  key <PRSC> { [ Menu ] };
};
EOF

In the above, we've created a couple of files called rules/evdev and symbols/custom in the .config/xkb directory of our home directory. Note: no need for sudo or modifying any system file.

In those files, we've defined a custom option, which we've called prtscmenu (you can use what you like, just replace all occurrences of the string), and finally we've used the "familiar" XKB syntax to override the <PRSC> ("print screen") key as desired. The syntax is the same as the one used in the accepted answer.

Finally, in order to apply this option (or disable it), on top of whichever keyboard happens to be loaded, one just needs to run:

# apply custom layout:
gsettings set org.gnome.desktop.input-sources xkb-options "['custom:prtscmenu']"
# disable custom layout:
gsettings set org.gnome.desktop.input-sources xkb-options "[]"

These can easily be set as aliases to make things even easier.

A couple more points:

You can have multiple such customizations defined and apply them separately (the xkb-option GSettings above accepts an array)
Unlike the accepted answer, this won't generate a wholly separate layout. So let's say you switch between different layouts in your workflow - say US and your own locale - you could apply the same prtscmenu customization atop each layout.
