Pascal - - 25 November 2002 - - Abstract - - This document describes how to configure X11R6.8 XKB from a user's - point a few. It converts basic configuration syntax and gives also - a few examples. - -1. Overview - -The XKB configuration is decomposed into a number of components. Selecting -proper parts and combining them back you can achieve most of configurations -you might need. Unless you have a completely atypical keyboard you really -don't need to touch any of xkb configuration files. - -2. Selecting XKB Configuration - -The easiest and the most natural way how to specify a keyboard mapping is to -use rules component. As its name suggests it describes a number of general -rules how to combine all bits and pieces into a valid and useful keyboard -mapping. All you need to do is to select a suitable rules file and then to -feed it with a few parameters that will adjust the keyboard behaviour to ful- -fill your needs. - -The parameters are: - - o XkbRules - files of rules to be used for keyboard mapping composition - - o XkbModel - name of model of your keyboard type - - o XkbLayout - layout(s) you intend to use - - o XkbVariant - variant(s) of layout you intend to use - - o XkbOptions - extra xkb configuration options - -The proper rules file depends on your vendor. In reality, the commonest file -of rules is xorg. For each rules file there is a description file named <ven- -dor-rules>.lst, for instance xorg.lst which is located in xkb configuration -subdirectory rules (for example /etc/X11/xkb/rules). - -2.1 Basic Configuration - -Let's say you want to configure a PC style America keyboard with 104 keys as -described in xorg.lst. It can be done by simply writing several lines from -below to you xorg.conf configuration file (previously known as -/etc/X11/XF86Config-4 or /etc/X11/XF86Config): - - Section "InputDevice" - Identifier "Keyboard1" - Driver "kbd" - - Option "XkbModel" "pc104" - Option "XkbLayout" "us" - Option "XKbOptions" "" - EndSection - -The values of parameters XkbModel and XkbLayout are really not surprising. -The parameters XkbOptions has been explicitly set to empty set of parameters. -The parameter XkbVariant has been left out. That means the default variant -named basic is loaded. - -Of course, this can be also done at runtime using utility setxkbmap. Shell -command loading the same keyboard mapping would look like: - - setxkbmap -rules xorg -model pc104 -layout us -option "" - -The configuration and the shell command would be very analogical for most -other layouts (internationalized mappings). - -2.2 Advanced Configuration - -You can use multi-layouts xkb configuration. What does it mean? Basically it -allows to load up to four different keyboard layouts at a time. Each such -layout would reside in its own group. The groups (unlike complete keyboard -remapping) can be switched very fast from one to another by a combination of -keys. - -Let's say you want to configure your new Logitech cordless desktop keyboard, -you intend to use three different layouts at the same time - us, czech and -german (in this order), and that you are used to Alt-Shift combination for -switching among them. - -Then the configuration snippet could look like this: - - Section "InputDevice" - Identifier "Keyboard1" - Driver "kbd" - - Option "XkbModel" "logicordless" - Option "XkbLayout" "us,cz,de" - Option "XKbOptions" "grp:alt_shift_toggle" - EndSection - -Of course, this can be also done at runtime using utility setxkbmap. Shell -command loading the same keyboard mapping would look like: - - setxkbmap -rules xorg -model logicordless -layout "us,cz,de" \ - -option "grp:alt_shift_toggle" - -2.3 Even More Advanced Configuration - -Okay, let's say you are more demanding. You do like the example above but you -want it to change a bit. Let's imagine you want the czech keyboard mapping to -use another variant but basic. The configuration snippet then changes into: - - Section "InputDevice" - Identifier "Keyboard1" - Driver "kbd" - - Option "XkbModel" "logicordless" - Option "XkbLayout" "us,cz,de" - Option "XkbVariant" ",bksl," - Option "XKbOptions" "grp:alt_shift_toggle" - EndSection - -That's seems tricky but it is not. The logic for settings of variants is the -same as for layouts, that means the first and the third variant settings are -left out (set to basic), the second is set to bksl (a special variant with an -enhanced definition of the backslash key). - -Analogically, the loading runtime will change to: - - setxkmap -rules xorg -model logicordless -layout "us,cz,de" \ - -variant ",bksl," -option "grp:alt_shift_toggle" - -2.4 Basic Global Options - -See rules/*.lst files. - -3. Direct XKB Configuration - -Generally, you can directly prescribe what configuration of each of basic xkb -components should be used to form the resulting keyboard mapping. This -method is rather "brute force". You precisely need to know the structure and -the meaning of all of used configuration components. - -This method also exposes all xkb configuration details directly into -xorg.conf configuration file which is a not very fortunate fact. In rare -occasions it may be needed, though. So how does it work? - -3.1 Basic Components - -There are five basic components used to form a keyboard mapping: - - o key codes - a translation of the scan codes produced by the keyboard - into a suitable symbolic form - - o types - a specification of what various combinations of modifiers pro- - duce - - o key symbols - a translation of symbolic key codes into actual symbols - - o geometry - a description of physical keyboard geometry - - o compatibility maps - a specification of what action should each key pro- - duce in order to preserve compatibility with XKB-unware clients - -3.2 Example Configuration - -Look at the following example: - - Section "InputDevice" - Identifier "Keyboard0" - Driver "kbd" - - Option "XkbKeycodes" "xorg" - Option "XkbTypes" "default" - Option "XkbSymbols" "en_US(pc104)+de+swapcaps" - Option "XkbGeometry" "pc(pc104)" - Option "XkbCompat" "basic+pc+iso9995" - EndSection - -This configuration sets the standard X server default interpretation of key- -board keycodes, sets the default modificator types. The symbol table is com- -posed of extended US keyboard layout in its variant for pc keyboards with 104 -keys plus all keys for german layout are redefined respectively. Also the -logical meaning of Caps-lock and Control keys is swapped. The standard key- -board geometry (physical look) is set to pc style keyboard with 104 keys. The -compatibility map is set to allow basic shifting, to allow Alt keys to be -interpreted and also to allow iso9995 group shifting. - -4. Keymap XKB Configuration - -It is the formerly used way to configure xkb. The user included a special -keymap file which specified the direct xkb configuration. This method has -been obsoleted by previously described rules files which are far more flexi- -ble and allow simpler and more intuitive syntax. It is preserved merely for -compatibility reasons. Avoid using it if it is possible. - - |
