kanshi

Kanshi uses a configuration file and a list of available displays to choose the right settings for each display. It's useful if your window manager doesn't support multiple display configurations (e.g. i3/Sway).

For now, it only supports:

• sysfs as backend
• udev as notifier (optional)
• Configuration file
  • GNOME (~/.config/monitors.xml)
  • Kanshi (see below)
• Sway as frontend

Usage

cargo install kanshi
touch ~/.config/kanshi/config
kanshi

Configuration file

Each monitor configuration is delimited by brackets. Each line has the same syntax as sway(5).

{
	output LVDS-1 disable
	output VGA-1 resolution 1600x900 position 0,0
}

{
	output LVDS-1 vendor CMN product 0x1484 serial 0x0 resolution 1600x900 scale 2
}

Running as a udev rule

Edit /etc/udev/rules.d/95-monitor-hotplug.rules:

KERNEL=="card0", SUBSYSTEM=="drm", ENV{WAYLAND_DISPLAY}="wayland-0", RUN+="/usr/bin/kanshi -n none"
