How to Install OpenLogi on Linux: Build from Source Guide

OpenLogi is primarily distributed for macOS via DMG and Homebrew, but Linux installation requires manually building the Rust crate workspace containing the GUI, Agent, and Overlay components.

OpenLogi is a native, local-first replacement for Logitech Options+. While the project provides pre-built binaries and Homebrew casks for macOS users, the underlying Rust codebase supports Linux through manual compilation. According to the AprilNEA/OpenLogi repository structure, the application consists of three tightly-coupled Rust crates that must be built together to install OpenLogi on Linux.

Understanding the Component Architecture

Before building, understand the three processes that comprise OpenLogi:

• OpenLogi GUI – The main application that presents the configuration UI and the Actions Ring overlay. Implementation resides in crates/openlogi-desktop/src/lib.rs.
• OpenLogi Agent – A background service that owns the HID++ device, handles DPI changes, SmartShift, and button events. Entry point is at crates/openlogi-agent/src/main.rs.
• OpenLogi Overlay – A thin client that draws the cursor-centered Actions Ring when invoked, implemented in crates/openlogi-overlay/src/platform.rs.

These components communicate via a local-socket IPC layer, as demonstrated by the openlogi_ipc crate contract.

Prerequisites for Linux Installation

To install OpenLogi on Linux, you need the Rust toolchain and system dependencies for HID access:

# Install Rust via rustup

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

# Install Linux HID development libraries (Ubuntu/Debian example)

sudo apt-get install libhidapi-dev libudev-dev libusb-1.0-0-dev

Building OpenLogi from Source

Since Linux lacks the DMG and Homebrew distribution channels available for macOS, compile the workspace directly:

# Clone the repository

git clone https://github.com/AprilNEA/OpenLogi.git
cd OpenLogi

# Build the complete workspace

cargo build --release

# The binaries will be available in:

# ./target/release/openlogi-agent

# ./target/release/openlogi-desktop (GUI)

Post-Build Configuration

Unlike macOS, which uses crates/openlogi-permissions/src/macos.rs to request Input Monitoring, Camera, and Microphone permissions via native dialogs, Linux requires manual udev rules for HID++ device access:

# Create udev rule for Logitech HID++ devices

echo 'SUBSYSTEM=="hidraw", ATTRS{idVendor}=="046d", MODE="0666", GROUP="plugdev"' | \
  sudo tee /etc/udev/rules.d/99-logitech.rules
sudo udevadm control --reload-rules

macOS Installation Reference

While installing OpenLogi on Linux requires building from source, the macOS installation process documented in README.md illustrates what the compiled components provide:

Method 1: Download the notarized DMG

• Download OpenLogi.dmg from the latest release
• Drag OpenLogi.app into /Applications

Method 2: Install via Homebrew

brew install --cask openlogi

To track upstream releases directly:

brew tap aprilnea/tap
brew install --cask aprilnea/tap/openlogi@latest

Verifying Agent Communication

After building and launching both the agent and GUI, verify the IPC connection works:

// Example: checking agent status from Rust (uses the IPC contract)
use openlogi_ipc::client::OpenLogiClient;
let mut client = OpenLogiClient::connect().await?;
let status = client.get_status().await?;
println!("Agent running: {}", status.running);

Summary

• OpenLogi uses a three-process architecture (GUI, Agent, Overlay) implemented in Rust crates
• Linux installation requires building from source using cargo build --release since pre-built binaries target macOS (DMG/Homebrew)
• Key source locations include crates/openlogi-agent/src/main.rs for the background service and crates/openlogi-desktop/src/lib.rs for the GUI
• Linux users must configure udev rules manually, unlike macOS which uses crates/openlogi-permissions/src/macos.rs for entitlement requests
• The IPC layer in openlogi_ipc enables communication between components once built

Frequently Asked Questions

Does OpenLogi provide pre-built binaries for Linux?

No. According to the repository source, official distribution channels currently provide notarized DMG files and Homebrew casks for macOS only. Linux users must compile the Rust workspace manually, targeting the crates in crates/openlogi-*.

What system permissions does OpenLogi require on Linux?

OpenLogi requires access to HID raw devices (/dev/hidraw*) to communicate with Logitech peripherals via the HID++ protocol. Unlike macOS, which prompts for Input Monitoring, Camera, and Microphone through the implementation in crates/openlogi-permissions/src/macos.rs, Linux requires manual udev rule configuration to grant the agent process device access.

Can I run the OpenLogi Agent without the GUI on Linux?

Yes. The architecture separates concerns between the Agent (device handling) and GUI (configuration interface). You can run cargo build --release -p openlogi-agent to build only the background service, which manages DPI changes, SmartShift, and button events independently of the desktop interface.
