Features

• Drag-and-drop layout — arrange monitors visually on an interactive canvas
• Multi-backend — auto-detects Hyprland, Sway, or Niri from the environment
• Cross-write — save a profile in any compositor and automatically generate config files for the others (e.g. configure in Hyprland → get Sway and Niri configs for free)
• Profile system — save, load, and switch between monitor configurations
• Hotplug daemon (moniqued) — automatically applies the best matching profile when monitors are connected or disconnected
• Display manager integration — syncs your layout to the login screen for SDDM (xrandr) and greetd (sway), with polkit rule for passwordless writes
• Workspace rules — configure workspace-to-monitor assignments (Hyprland/Sway)
• HDR & color management — color management presets, 10-bit output, ICC profiles, SDR brightness/saturation and per-monitor EDID luminance overrides (Hyprland monitorv2)
• Live preview — OSD overlay to identify monitors (double-click)
• Workspace migration — automatically moves workspaces to the primary monitor when their monitor is disabled or unplugged (reverted if you click "Revert")
• Clamshell mode — disable the internal laptop display when external monitors are connected (manual toggle in the toolbar or automatic via daemon preferences); the daemon also monitors the lid state via UPower D-Bus
• Confirm-or-revert — 10-second countdown after applying, auto-reverts if display is unusable
• CLI interface — list, query, and switch profiles from the terminal (--list-profiles, --current-profile, --switch-profile), perfect for hotkey bindings
• Custom config directory — write generated monitor config files to a custom path instead of the compositor default (via Preferences or --config-dir)
• Custom config filename — change the generated file's base name (default monitors) from Preferences → Config Output; the right extension is added per compositor (.kdl/.conf/.lua) and subdirectories are supported (e.g. cfg/display)
• Active profile tracking — the last applied profile is persisted across GUI, CLI, and daemon, queryable via --current-profile

Installation

AUR (Arch Linux / CachyOS)

yay -S monique

Or manually:

git clone https://aur.archlinux.org/monique.git
cd monique
makepkg -si

NixOS / Nix

With flake (recommended) -- add it as an input and use the NixOS module:

# flake.nix
inputs.monique.url = "github:ToRvaLDz/monique";

# configuration.nix (via module)
{ inputs, ... }: {
  imports = [ inputs.monique.nixosModules.default ];
  programs.monique.enable = true;
}

Run without installing:

nix run github:ToRvaLDz/monique

Install to user profile:

nix profile install github:ToRvaLDz/monique

With overlay:

nixpkgs.overlays = [ inputs.monique.overlays.default ];
environment.systemPackages = [ pkgs.monique ];

Polkit note: the NixOS module automatically installs the polkit rule for passwordless SDDM/greetd writes. Disable with programs.monique.enablePolkit = false.

PyPI

pip install monique

From source

git clone https://github.com/ToRvaLDz/monique.git

Usage

GUI

monique

Open the graphical editor to arrange monitors, set resolutions, scale, rotation, and manage profiles.

CLI

# List all saved profiles (JSON array)
monique --list-profiles

# Get the currently active profile
monique --current-profile

# Switch to a profile
monique --switch-profile "Office"

# Switch with a custom config output directory
monique --config-dir ~/my-hypr-config --switch-profile "Office"

Bind monique --switch-profile <name> to any compositor hotkey for quick profile switching.

Daemon

moniqued

Or enable the systemd user service:

systemctl --user enable --now moniqued

The daemon auto-detects the active compositor and listens for monitor hotplug events. When a monitor is connected or disconnected, it waits 500ms (debounce) then applies the best matching profile. On Niri, the daemon uses udev DRM events (via pyudev) for reliable hardware hotplug detection. Orphaned workspaces are automatically migrated to the primary monitor on Hyprland/Sway (configurable via Preferences > Migrate workspaces).

Clamshell mode

On laptops, the daemon can automatically disable the internal display when external monitors are connected. Enable it from the GUI: Menu > Preferences > Clamshell Mode.

The daemon also monitors the laptop lid state via UPower D-Bus: closing the lid disables the internal display, opening it re-enables it. On desktop PCs (no lid detected), clamshell mode simply disables any internal-type output (eDP, LVDS) whenever external monitors are present.

Note: if your system suspends on lid close, set HandleLidSwitch=ignore in /etc/systemd/logind.conf so the daemon can handle it instead.

Behavior per environment

Environment	Detection	Events
Hyprland	$HYPRLAND_INSTANCE_SIGNATURE	monitoradded / monitorremoved via socket2
Sway	$SWAYSOCK	output events via i3-ipc subscribe
Niri	$NIRI_SOCKET	udev DRM subsystem (with pyudev), IPC fallback
Neither	Warning, retry every 5s	—

Display manager integration

Monique can sync your monitor layout to the login screen for supported display managers.

Display Manager	Method	Config path
SDDM	xrandr via Xsetup script	/usr/share/sddm/scripts/Xsetup
greetd (sway)	sway output commands	/etc/greetd/monique-monitors.conf

A polkit rule is included to allow passwordless writes:

# Installed automatically by the PKGBUILD to:
# /usr/share/polkit-1/rules.d/60-com.github.monique.rules

Toggle from the GUI: Menu > Preferences > Update SDDM Xsetup or Update greetd config.

HDR and color management

Available on Hyprland 0.50+, where Monique writes the monitorv2 { … } block syntax (auto-detected from the running compositor). Sway and Niri expose no equivalent options, so these controls stay disabled there.

Select a monitor and scroll the properties sidebar. Advanced group:

Control	Hyprland key	Values
Color Management	cm	auto, srgb, dcip3, dp3, adobe, wide, edid, hdr, hdredid
Bit Depth	bitdepth	8 or 10 (10 recommended for HDR)
ICC Profile	icc	absolute path, Hyprland 0.55+ (takes precedence over cm)
SDR Brightness	sdrbrightness	0.0 to 5.0, default 1.0
SDR Saturation	sdrsaturation	0.0 to 5.0, default 1.0

HDR / EDID Override group, for panels whose EDID reports wrong or missing capabilities:

Control	Hyprland key	Values
SDR EOTF	sdr_eotf	Global / sRGB / Gamma 2.2
Supports HDR	supports_hdr	Auto / Force
Supports Wide Color	supports_wide_color	Auto / Force
SDR Min Luminance	sdr_min_luminance	0.0 to 10.0
SDR Max Luminance	sdr_max_luminance	0.0 to 2000.0
Min Luminance	min_luminance	0.0 to 2000.0
Max Luminance	max_luminance	0.0 to 10000.0
Max Avg Luminance	max_avg_luminance	0.0 to 10000.0

Rows marked inactive only take effect when Color Management is set to hdr or hdredid, or when Hyprland's auto HDR settings drive them. Values left at their default are omitted from the generated config, so Hyprland keeps its own defaults.

Washed-out SDR content on an HDR display is the usual first problem: raise SDR Brightness above 1.0 and adjust SDR Saturation, and try SDR EOTF → Gamma 2.2. hdredid uses the luminance data from your display's EDID, which helps when that data is accurate and hurts when it is not, which is what the manual luminance overrides are for.

Note: Monique only writes the compositor-side configuration. Whether a given application or game actually outputs HDR depends on it, and on Proton/gamescope, not on the monitor configurator.

Configuration

All configuration is stored in ~/.config/monique/:

~/.config/monique/
├── profiles/
│   ├── Home.json
│   └── Office.json
└── settings.json

Monitor config files are written to the compositor's config directory:

• Hyprland: ~/.config/hypr/monitors.conf and/or ~/.config/hypr/monitors.lua
• Sway: ~/.config/sway/monitors.conf
• Niri: ~/.config/niri/monitors.kdl

For Hyprland's legacy hyprlang config, add source = ~/.config/hypr/monitors.conf to hyprland.conf. For Hyprland 0.55+ Lua config, add require("monitors") to hyprland.lua.

By default Monique writes both Hyprland formats so either config style keeps working. If you only use one, pick it in Preferences → Hyprland Config Format (legacy, lua, or both, stored as hypr_config_format in settings.json). Switching away from a format leaves the previously generated file on disk: delete it, or drop its source/require line from your Hyprland config, otherwise Hyprland keeps applying the stale layout.

To use a custom output directory, set it in Preferences → Config Output or pass --config-dir on the command line.

To change the generated file's base name (default monitors), set Monitor config filename in Preferences → Config Output (stored as monitor_config_name in settings.json). The value is a base name without extension, relative to the compositor's config directory, and may include subdirectories (e.g. cfg/display → cfg/display.kdl for Niri, cfg/display.conf for Sway, and cfg/display.conf/cfg/display.lua for Hyprland). Absolute paths and .. segments are rejected. For Niri, the include line in config.kdl is kept in sync with the configured name; if you change the name later, update your Hyprland source/require lines to match.
