crandr 1.6.1

This is a unifying wrapper around xrandr and swaymsg to control your monitors/outputs,

This is a unifying wrapper around xrandr and swaymsg to control your monitors/outputs, mainly intended for setups where only one or two monitors are enabled at the same time.

xrandr's syntax is too verbose for direct usage and too explicit to use it in an i3/sway config file. This script tries to make things easier.

Examples

• crandr cycles through all connected monitors.
• crandr toggle toggles between the internal monitor and an external monitor.
• crandr extend left turns on another monitor and positions it left of the currently enabled monitor.
• crandr mirror turns on another monitor and mirrors the displayed content. If the monitors have different resolutions the internal monitor is scaled to match the resolution of the external monitor. If you want another monitor to be scaled you can specify the monitor which should not be scaled with --original. (Sway does not support mirroring yet, see this issue.)
• crandr scale .8 if everything is displayed too small and you want to make things bigger.
• crandr rotate left rotates the content of the currently enabled monitor so that the top of the content is at the left edge of the monitor.
• crandr reset external enables the external monitor with default rotation and scaling and turns off all other monitors (the internal monitor).
• crandr list to list all connected monitors.

Files

crandr creates two files:

• a config file ~/.config/crandr/config, when running crandr config
• a bash completion script ~/.local/share/crandr/complete.bash, if it does not exit or is outdated. You need to source this file in your bashrc in order to activate the bash completion.

If you are unhappy with the default location of these scripts you can inject appdirs, xdgappdirs or platformdirs into the virtual environment (pipx inject crandr appdirs).

Installation

$ pipx install crandr

Dependencies

• Python >= 3.8
• xrandr and RandR >= version 1.3 or swaymsg

Dependencies for running the tests:

• mypy
• pytest

Alternatives

• arandr (for X) and wdisplays (for wayland) are graphical user interfaces to control monitors.
• autorandr (for X) and kanshi (for wayland) are programs which automatically enable output profiles when connecting and disconnecting monitors.
