7.6. Configuring the Linux Console

This section discusses how to configure the console and consolelog bootscripts that set up the keyboard map, console font and console kernel log level. If non-ASCII characters (e.g., the copyright sign, the British pound sign and Euro symbol) will not be used and the keyboard is a U.S. one, much of this section can be skipped. Without the configuration file, the console bootscript will do nothing.

The console and consolelog script reads the /etc/sysconfig/console file for configuration information. Decide which keymap and screen font will be used. Various language-specific HOWTOs can also help with this, see http://www.tldp.org/HOWTO/HOWTO-INDEX/other-lang.html. If still in doubt, look in the /lib/kbd directory for valid keymaps and screen fonts. Read loadkeys(1) and setfont(8) manual pages to determine the correct arguments for these programs.

The /etc/sysconfig/console file should contain lines of the form: VARIABLE="value". The following variables are recognized:

LOGLEVEL

This variable specifies the log level for kernel messages sent to the console as set by dmesg. Valid levels are from "1" (no messages) to "8". The default level is "7".

KEYMAP

This variable specifies the arguments for the loadkeys program, typically, the name of keymap to load, e.g., “es”. If this variable is not set, the bootscript will not run the loadkeys program, and the default kernel keymap will be used.

KEYMAP_CORRECTIONS

This (rarely used) variable specifies the arguments for the second call to the loadkeys program. This is useful if the stock keymap is not completely satisfactory and a small adjustment has to be made. E.g., to include the Euro sign into a keymap that normally doesn't have it, set this variable to “euro2”.

FONT

This variable specifies the arguments for the setfont program. Typically, this includes the font name, “-m”, and the name of the application character map to load. E.g., in order to load the “lat1-16” font together with the “8859-1” application character map (as it is appropriate in the USA), set this variable to “lat1-16 -m 8859-1”. In UTF-8 mode, the kernel uses the application character map for conversion of composed 8-bit key codes in the keymap to UTF-8, and thus the argument of the "-m" parameter should be set to the encoding of the composed key codes in the keymap.

UNICODE

Set this variable to “1”, “yes” or “true” in order to put the console into UTF-8 mode. This is useful in UTF-8 based locales and harmful otherwise.

LEGACY_CHARSET

For many keyboard layouts, there is no stock Unicode keymap in the Kbd package. The console bootscript will convert an available keymap to UTF-8 on the fly if this variable is set to the encoding of the available non-UTF-8 keymap.

Some examples:

Note

The /etc/sysconfig/console file only controls the Linux text console localization. It has nothing to do with setting the proper keyboard layout and terminal fonts in the X Window System, with ssh sessions or with a serial console. In such situations, limitations mentioned in the last two list items above do not apply.
