NAME <\/a> <\/h2>\n

keyboard \u2212 keyboard configuration file<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The keyboard<\/b> file describes the properties of the keyboard. It is read by setupcon<\/b>(1) in order to configure the keyboard on the console. In Debian systems the default keyboard layout is described in \/etc\/default\/keyboard<\/i> and it is shared between X and the console.<\/p>\n

The specification of the keyboard layout in the keyboard<\/b> file is based on the XKB<\/small> options XkbModel, XkbLayout, XkbVariant and XkbOptions. Unfortunately, there is little documentation how to use them. Description of all possible values for these options can be found in the file xorg.lst<\/i>.<\/p>\n

You might want to read \u201cThe XKB Configuration Guide\u201d by Kamil Toman and Ivan U. Pascal:<\/p>\n

http:\/\/www.xfree86.org\/current\/XKB-Config.html<\/p>\n

http:\/\/pascal.tsu.ru\/en\/xkb\/
http:\/\/www.charvolant.org\/~doug\/xkb\/<\/p>\n

The complete XKB-specification can be found on<\/p>\n

http:\/\/xfree86.org\/current\/XKBproto.pdf<\/p>\n

The file keyboard<\/b> consists of variable settings in POSIX<\/small> format:<\/p>\n

VARIABLE<\/i>=VALUE<\/i><\/p>\n

Only one assignment is allowed per line. Comments (starting with \u2019#\u2019) are also allowed.<\/p>\n

OPTIONS <\/a> <\/h2>\n

The following variables can be set.
XKBMODEL<\/b><\/p>\n

Specifies the XKB<\/small> keyboard model name. Default: pc105<\/b> on most platforms.<\/p>\n

XKBLAYOUT<\/b><\/p>\n

Specifies the XKB<\/small> keyboard layout name. This is usually the country or language type of the keyboard. Default: us<\/b> on most platforms<\/p>\n

XKBVARIANT<\/b><\/p>\n

Specifies the XKB<\/small> keyboard variant components. These can be used to further specify the keyboard layout details. Default: not set.<\/p>\n

XKBOPTIONS<\/b><\/p>\n

Specifies the XKB<\/small> keyboard option components. Options usually relate to the behavior of the special keys (, , , , etc.)<\/small> Default: not set.<\/p>\n

BACKSPACE<\/b><\/p>\n

Determines the behavior of <\/small> and <\/small> keys on the console. Allowed values: bs<\/b>, del<\/b> and guess<\/b>. In most cases you can specify guess<\/b> here, in which case the current terminal settings and the kernel of your operating system will be used to determine the correct value. Value bs<\/b> specifies VT100-conformant behavior: <\/small> will generate ^H<\/b> (ASCII BS)<\/small> and <\/small> will generate ^?<\/b> (ASCII DEL).<\/small> Value del<\/b> specifies VT220-conformant behavior: <\/small> will generate ^?<\/b> (ASCII DEL)<\/small> and <\/small> will generate a special function sequence.<\/p>\n\n\n
<\/td>\n\n

KMAP<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Usually this variable will be unset but if you don\u2019t want to use a XKB<\/small> layout on the console, you can specify an alternative keymap here. Specify a file that is suitable as input for loadkeys<\/b>(1) on Linux or for kbdcontrol<\/b>(1) on FreeBSD.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

FILES <\/a> <\/h2>\n

The standard location of the keyboard<\/b> file is \/etc\/default\/keyboard<\/i>. Description of all available keyboard models, layouts, variants and options is available in \/usr\/share\/X11\/xkb\/rules\/xorg.lst<\/i>. In most cases, in \/lib\/kbd\/keymaps\/<\/i> you will find several keymaps that can be used with the variable KMAP<\/b>.<\/p>\n

NOTES <\/a> <\/h2>\n

In Debian systems, changes in \/etc\/default\/keyboard<\/i> do not become immediately visible to X. You should either reboot the system, or use<\/p>\n

udevadm trigger –subsystem-match=input –action=change<\/p>\n

In order to activate the changes on the console, run setupcon<\/b>(1).<\/b><\/p>\n

BUGS <\/a> <\/h2>\n

When a triple-layout is used on the console, i.e. a layout with three XKB<\/small> groups, then the group toggling happens in the following way: Group1 \u2212> Group2 \u2212> Group1 \u2212> Group3.<\/p>\n

On FreeBSD triple- and quadruple-layouts are not supported on the console (only the first and the second layout are taken into account).<\/p>\n

The option grp:shifts_toggle<\/b> is not supported on the console.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

The following configuration will give you the standard US QWERTY<\/small> layout (us<\/b>). The key

<\/small> will act as a compose key (compose:menu<\/b>) and <\/small> will act as third control key (ctrl:nocaps<\/b>).<\/p>\n

XKBLAYOUT=us
XKBVARIANT=
XKBOPTIONS=compose:menu,ctrl:nocaps<\/p>\n

In the following configuration the right <\/small> key (grp:toggle<\/b>) will toggle between US QWERTY<\/small> layout (us<\/b>) and Greek (gr<\/b>) layout. The option grp_led:scroll<\/b> is ignored on the console but in X in means to use the ScrollLock keyboard led as indicator for the current layout (US or Greek).<\/p>\n

XKBLAYOUT=us,gr
XKBVARIANT=
XKBOPTIONS=grp:toggle,grp_led:scroll<\/p>\n

In the following configuration the +<\/small> key combination will toggle (grp:ctrl_shift_toggle<\/b>) between French keyboard (fr<\/b>) without dead keys (nodeadkeys<\/b>) and British (gb<\/b>) \u201cDvorak\u201d (dvorak<\/b>) keyboard. The right <\/small> key will be a compose-key (compose:rwin<\/b>) and the right <\/small> key will function as AltGr (lv3:lalt_switch<\/b>).<\/p>\n

XKBLAYOUT=fr,gb
XKBVARIANT=nodeadkeys,dvorak
XKBOPTIONS=grp:ctrl_shift_toggle,compose:rwin,lv3:ralt_switch<\/p>\n
