KMSCON.CONF(5)

NAME
kmscon.conf - Configuration file for KMS/DRM based System Console

DESCRIPTION

kmscon.conf is the configuration file to control the behavior of kmscon and adjust it to your system-setup. It allows to remap the bindings of keyboard-shortcuts, define the desired keyboard-layout, select font attributes for text-rendering, hardware-accelerationn, orientation of output and much more.

Below is a complete list of all recognized Options, their meaning and possible values. In section Example is a typical real-world sample of a configuration to guide you in creating your own.

OPTIONS

Below is a complete list of all recognized options, their meaning and possible values.

verbose
    Make kmscon be very chatty about what it is doing. It prints to stdout unless redirected. Off if not present in kmsconf.conf or commented out. (default: off)

debug
    Let kmscon be even more chatty. The text-output goes to stdout or any file it was redirected to. Off if not present in kmsconf.conf or commented out. (default: off)

silent
    Suppress notices and warnings. (default: off)

configdir
    Path to config directory. (default: /etc/kmscon)

vt
    Select which VT to run on. (default: auto)

switchvt
    Automatically switch to VT. (default: on)

libseat
    Use libseat for seat management. (default: off)

session-max
    Maximum number of sessions. (default: 50)

session-control
    Allow keyboard session-control. (default: off)

login
    Start the given login process instead of the default process; all arguments following '--' will be be parsed as argv to this process. No more options after '--' will be parsed so use it at the end of the argument string. (default: /bin/login -p)

term
    Value of the TERM environment variable for the child process. (default: kmscon)

reset-env
    Reset environment before running child process. (default: on)

backspace-delete
    Send delete character when backspace is pressed. (default: on)

palette
    Select the used color palette. (default: default)

sb-size
    Size of the scrollback-buffer in lines. (default: 1000)

bell
    Enable bell forwarding to the VT. When enabled, the BEL character (0x07) from applications is forwarded to the underlying VT. (default: off)

xkb-model
    Set XkbModel for input devices. (default: unset)

xkb-layout
    Set XkbLayout for input devices. (default: unset)

xkb-variant
    Set XkbVariant for input devices. (default: unset)

xkb-options
    Set XkbOptions for input devices. (default: unset)

xkb-keymap
    Use a predefined keymap for input devices. (default: unset)

xkb-repeat-delay
    Initial delay for key-repeat in ms. (default: 250)

xkb-repeat-rate
    Delay between two key-repeats in ms. (default: 50)

mouse
    Enable mouse/touchpad/trackpoint in kmscon (default: on). It allows to select, and copy/paste text with a pointing device, and also to scroll with the mouse wheel. It's still experimental, and may not work with specific devices.

natural-scrolling
    Invert the mouse wheel direction (natural scrolling). When enabled, scrolling up with the wheel scrolls down and vice versa. (default: off)

soft-cursor
    Force software cursor, if hardware cursor is not working properly. (default: off)

dpms-timeout
    Set screen timeout in seconds (default: 600 = 10 minutes). When enabled, the screen will automatically turn off (DPMS OFF) after the specified period of keyboard and mouse inactivity. Any keyboard or mouse input will turn the screen back on and reset the timer. This feature is useful for power saving on systems where the screen is not always needed. Set to 0 to disable.

grab-scroll-up
    Shortcut to scroll up. (default: <Shift>Up)

grab-scroll-down
    Shortcut to scroll down. (default: <Shift>Down)

grab-page-up
    Shortcut to scroll page up. (default: <Shift>Prior)

grab-page-down
    Shortcut to scroll page down. (default: <Shift>Next)

grab-zoom-in
    Shortcut to increase font size. (default: <Ctrl>Plus)

grab-zoom-out
    Shortcut to decrease font size. (default: <Ctrl>Minus)

grab-session-next
    Switch to next session. (default: <Ctrl><Logo>Right)

grab-session-prev
    Switch to previous session. (default: <Ctrl><Logo>Left)

grab-session-close
    Close current session. (default: <Ctrl><Logo>BackSpace)

grab-terminal-new
    Create new terminal session. (default: <Ctrl><Logo>Return)

grab-rotate-cw
    Rotate output clock-wise. (default: <Logo>Plus)

grab-rotate-ccw
    Rotate output counter-clock-wise. (default: <Logo>Minus)

grab-reboot
    Reboot the system when this keyboard shortcut is pressed. This option is disabled by default. The reboot behavior follows the system-wide setting in /proc/sys/kernel/ctrl-alt-del: when set to 0 (default), a graceful reboot is performed by sending SIGINT to init (PID 1); when set to a value greater than 0, an immediate hard reboot is performed after syncing disk buffers. Example: grab-reboot=<Ctrl><Alt>Delete (default: disabled)

drm
    Use DRM if available. (default: on)

hwaccel
    Use 3D hardware-acceleration if available. (default: off)

gpus
    GPU selection mode. (default: all)

use-original-mode
    Use the original KMS video mode. (default: on)

mode
    Set the resolution to {width}x{height}

multi-monitor {clone,largest}
    When there are multiple monitors, this option controls how the monitors are used.

    `clone': All monitors will have the same size. The smallest monitor will be used to determine the size.

    `largest': The largest monitor will be used to determine the size. The other monitors will be disabled. If multiple monitors have the largest size, they will all be used.

    default: clone

rotate
    Orientation of output to use. (default: normal)

font-engine
    Font engine to use. (default: freetype)

font-size
    Font size in pixels. (default: 16)
