way-displays - Auto Manage Your Wayland Displays
way-displays [OPTIONS...] [COMMAND]
way-displays manages your wayland displays:
- Sets mode:
- user specified resolution/refresh OR
- monitor preferred OR
- highest resolution/refresh
- Enables VRR / adaptive sync
- Arranges in a row or a column
- Auto scales based on DPI: 96 is a scale of 1
- Reacts when displays are plugged/unplugged
- Reacts when laptop lid is closed/opened and no other displays connected
Works out of the box: no configuration required.
Background process that performs the management. Configuration is read from a file discovered in order:
$XDG_CONFIG_HOME/way-displays/cfg.yaml
$HOME/.config/way-displays/cfg.yaml
/usr/local/etc/way-displays/cfg.yaml
/etc/way-displays/cfg.yaml
The file may be specified via the --config
option.
cfg.yaml will be monitored for changes, which will be immediately applied.
See the default /etc/way-displays/cfg.yaml and https://github.com/alex-courtis/way-displays/blob/master/doc/CONFIGURATION.md for details on individual configurable settings.
Server is run when no commands are specified.
Server responds to IPC requests to fetch and mutate state: https://github.com/alex-courtis/way-displays/blob/master/doc/IPC.md
Manages the server. The active configuration and display state may be inspected, and the configuration modified.
The active configuration can be written to disk, however any comments and formatting will be lost.
way-displays is known to work on the sway and river compositors. It may work on any wlroots compositor that supports the WLR Output Management protocol.
The user must be a member of the input
group.

You can configure displays by name or description. You can find these by looking at the logs e.g.
DP-3 Arrived:
info:
name: 'DP-3'
make: 'Monitor Maker'
model: 'ABC123'
desc: 'Monitor Maker ABC123 (DP-3 via HDMI)'
It is recommended to use the description rather than the name, as the name may change over time and will most likely be different on different PCs.
The description does contain information about how it is connected, so strip that out. In the above example, you would use the description 'Monitor Maker ABC123'.
The name should be at least 3 characters long, to avoid any unwanted extra matches.
