Please see DEVICES.md for further information

NOTE

Experimental drivers are disabled in the default configuration!

To enable support for experimental drivers, please edit /etc/eruption/eruption.conf and set

driver_maturity_level = "experimental"

After that, please restart the eruption daemon

sudo systemctl restart eruption.service

Important Information

⚠️ This project is still in the early stages of development, and thus may contain some possibly serious bugs. ⚠️

For a more mature RGB lighting solution please also consider the following alternatives

OpenRGB - OPEN SOURCE RGB LIGHTING CONTROL THAT DOESN'T DEPEND ON MANUFACTURER SOFTWARE
https://openrgb.org/
https://gitlab.com/CalcProgrammer1/OpenRGB

For configuring gaming mice you may want to consider:

libratbag/piper - libratbag A DBus daemon to configure input devices, mainly gaming mice https://github.com/libratbag

For key remapping without LED specific features

If you are more interested in simply remapping your keys at the input level, or even require application-specific key remapping you should consider:

Keyd - A key remapping daemon for linux https://github.com/rvaiya/keyd

Troubleshooting

If you ever need to forcefully disable the Eruption daemon you may do so by adding the following text snippet to the bootloader's (e.g. GRUB) kernel command line:

systemd.mask=eruption.service

Or with systemctl to mask the service:

sudo systemctl mask eruption.service

You can always re-enable the Eruption service with the command:

sudo systemctl unmask eruption.service

Design Overview

Introduction

Eruption is a Linux daemon written in the Rust programming language. Eruption consists of a core daemon providing an integrated Lua interpreter, and additional plugin components. Its primary usage is to execute Lua scripts that may react to certain events on the system like e.g. Timer tick, Key press or Mouse move and subsequently control the connected LED devices and/or transform the user input via the integrated programmable macro feature. Eruption plugins may export additional functionality to the Lua scripting engine. Multiple Lua scripts may be run in parallel, each one in its own VM thread. A Lua script shall compute some kind of effect resulting in a 'color map'. Each Lua scripts 'submitted color map' will be combined with all other scripts 'submitted color maps' using a compositor that performs an alpha blending step on each 'color map' before it finally gets sent to the connected LED devices.

Systems Architecture

Eruption is split into multiple independent processes: eruption, the core daemon that handles hardware access running as the root user, and multiple session daemons, most notably eruption-audio-proxy that provides audio related functionality to the core daemon, and eruption-process-monitor that is able to automatically switch profiles based on system usage. Both of these session daemons run as the respective logged-in user.

Installation

To install the latest git snapshot please use the package named eruption-git instead of the stable package eruption

Arch Linux and derivatives like ArcoLinux or Manjaro

paru -Syu aur/eruption

systemctl --user enable --now eruption-fx-proxy.service
systemctl --user enable --now eruption-audio-proxy.service
systemctl --user enable --now eruption-process-monitor.service

sudo systemctl enable --now eruption.service

Fedora based

sudo dnf copr enable x3n0m0rph59/eruption
sudo dnf install eruption

systemctl --user enable --now eruption-fx-proxy.service
systemctl --user enable --now eruption-audio-proxy.service
systemctl --user enable --now eruption-process-monitor.service

sudo systemctl enable --now eruption.service

Ubuntu or Pop!_OS

sudo add-apt-repository ppa:x3n0m0rph59/eruption
sudo apt update
sudo apt install eruption

systemctl --user enable --now eruption-fx-proxy.service
systemctl --user enable --now eruption-audio-proxy.service
systemctl --user enable --now eruption-process-monitor.service

sudo systemctl enable --now eruption.service

From Source

git clone https://github.com/eruption-project/eruption.git
cd eruption
make
sudo make install
make start

To remove Eruption from your system run:

make stop
sudo make uninstall

Please refer to INSTALL.md for further information, e.g. the dependencies you need to install to be able to successfully build Eruption from source.

After Setup

You may want to try the Eruption Profile Switcher GNOME Shell extension that enables easy switching of profiles on the fly

Support for Audio Playback and Capture

Eruption currently has built-in support for the following audio APIs:

• PipeWire (via the PulseAudio interface of PipeWire)
• PulseAudio

Audio support is provided by eruption-audio-proxy.service.

The eruption-audio-proxy Daemon

As of Eruption 0.1.23 it is no longer necessary to grant the root user full access to the PipeWire or PulseAudio session instance. Therefore, it is no longer required to edit configuration files. Just enable the eruption-audio-proxy session daemon and assign a device monitor to listen on, e.g. by using pavucontrol.

systemctl --user enable --now eruption-audio-proxy.service

NOTE: Please do not use sudo in front of the command since it has to act on the session instance of systemd

Next, switch to a profile that utilizes the audio API of Eruption:

eruptionctl switch profile spectrum-analyzer-swirl.profile

Then use pavucontrol to assign a monitor of an audio device to the Eruption audio grabber.

NOTE: You have to select a profile that makes use auf the audio grabber first, otherwise the eruption-audio-proxy will not open an audio device for recording, and therefore will not be listed
