hyprmoncfg

Hyprland monitor configuration that actually works.

You know the drill. You plug in a monitor. Nothing happens the way you want. You open hyprland.conf, squint at coordinate math, guess at monitor= lines, reload, realize the positions are wrong, edit again. You go to a conference, plug into a projector, and start the whole dance over.

hyprmoncfg fixes this.

Open a terminal. See your monitors laid out spatially. Drag them where you want. Save the layout as a profile. Next time you plug in the same monitors, the daemon applies it automatically.

Two binaries. Zero runtime dependencies. Runs over SSH. No Python, no GTK, no D-Bus.

The problem with Hyprland monitor configuration

Configuring monitors in Hyprland is painful:

• No visual editor. You write monitor= lines by hand and pray the coordinates are right.
• No profiles. Unplug your laptop from your desk, plug into a projector at a conference, and you're manually editing config files backstage.
• No automatic switching. Hotplug a monitor and Hyprland does its best guess. Your careful layout? Gone.
• Connector names are unstable. DP-1 and DP-2 swap randomly between boots. Workspace bindings break.
• Existing tools pull in the world. Python runtimes, GTK libraries, GObject introspection. Just to move a rectangle on a screen.

The solution

hyprmoncfg ships two binaries:

hyprmoncfg	TUI + CLI for layout editing, profile management, and workspace planning
hyprmoncfgd	Background daemon that auto-applies the best matching profile on hotplug

Both use the same apply engine: write monitors.conf atomically, reload Hyprland, verify the result, revert if anything is wrong.

Features

• Spatial layout editor -- drag monitors on a canvas, see them move in real time
• Per-monitor inspector -- mode, scale, VRR, transform, exact position
• Named profiles -- save "desk", "conference", "home-office", switch between them instantly
• Hardware-identity matching -- profiles follow your monitors, not connector names
• Hotplug-aware daemon -- plug in, walk away, the right profile is applied automatically
• Workspace planner -- sequential, interleave, or manual workspace placement across monitors
• Safe apply with revert -- a 10-second confirmation window so you never get locked out
• Source-chain verification -- refuses to write a monitors.conf that Hyprland isn't even reading
• Zero runtime dependencies -- compiled Go, statically linked, nothing to install

Quick start

Build:

go build -o bin/hyprmoncfg ./cmd/hyprmoncfg
go build -o bin/hyprmoncfgd ./cmd/hyprmoncfgd

Install:

install -Dm755 bin/hyprmoncfg  ~/.local/bin/hyprmoncfg
install -Dm755 bin/hyprmoncfgd ~/.local/bin/hyprmoncfgd

Use:

hyprmoncfg                 # open the TUI
hyprmoncfg save desk       # save current layout as "desk"
hyprmoncfg apply desk      # apply it later

Start the daemon:

mkdir -p ~/.config/systemd/user
cp packaging/systemd/hyprmoncfgd.local.service ~/.config/systemd/user/hyprmoncfgd.service
systemctl --user daemon-reload
systemctl --user enable --now hyprmoncfgd

Dotfiles integration

Profiles live in ~/.config/hyprmoncfg/profiles/. They're plain JSON files, one per profile. Add the directory to your dotfile manager and your layouts roam across every machine you own.

With chezmoi:

chezmoi add ~/.config/hyprmoncfg

Now your desk at home, your laptop on the road, and your Raspberry Pi in the closet all share the same profile library. The daemon picks the right one based on what's actually plugged in.

You don't commit monitors.conf. You commit your profiles. The tool writes monitors.conf for you.
