vconsole.conf
VCONSOLE.CONF(5) vconsole.conf VCONSOLE.CONF(5)NAME
vconsole.conf - configuration file for the virtual console
SYNOPSIS
/etc/vconsole.conf
DESCRIPTION
The /etc/vconsole.conf file configures the virtual console, i.e. keyboard mapping and console font.
The basic file format of the vconsole.conf is a newline-separated list environment-like shell-compatible variable assignments. It is
possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported,
allowing applications to read the file without implementing a shell compatible execution engine.
Note that the kernel command line options vconsole.keymap=, vconsole.keymap.toggle=, vconsole.font=, vconsole.font.map=,
vconsole.font.unimap= may be used to override the console settings at boot.
Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only
as fallback.
OPTIONS
The following options are understood:
KEYMAP=, KEYMAP_TOGGLE=
Configures the key mapping table of for they keyboard. KEYMAP= defaults to us if not set. The KEYMAP_TOGGLE= can be used to configured
a second toggle keymap and is by default unset.
FONT=, FONT_MAP=, FONT_UNIMAP=
Configures the console font, the console map and the unicode font map. FONT= defaults to latarcyrheb-sun16.
EXAMPLE
Example 1. German keyboard and console
/etc/vconsole.conf:
KEYMAP=de-latin1
FONT=latarcyrheb-sun16
