LACT

Project Overview

LACT (Linux GPU Control Application) allows you to control your AMD, NVIDIA, or Intel GPU on a Linux system.

Key Features

• Detailed GPU information: name, manufacturer, VBIOS info, VRAM info, hardware unit info, Resizable BAR status
• Monitoring: configurable historical charts, throttling info, CSV export
• Power configuration: power cap, power states (AMD only)
• Thermal configuration: custom fan curves (AMD/NVIDIA), firmware thermal options
• Overclocking: GPU/VRAM clocks, GPU undervolting
• Settings profiles: automatic activation based on running processes
• OpenTelemetry metrics exporter

Target Audience

• Linux gamers and overclocking enthusiasts
• System administrators who need GPU monitoring
• Developers who want to optimize GPU performance

Quick Start

1. Arch Linux: pacman -S lact
2. Debian/Ubuntu: download .deb from Releases
3. Fedora: use Copr repository or download RPM
4. Launch LACT GUI
5. GPU configuration is handled by a system service independent of graphical sessions

Core Advantages

• Supports AMD, NVIDIA, and Intel GPUs
• System service mode supports headless scenarios
• Open-source and free, continuously updated

System Requirements

• OS: Linux
• Architectures: x86_64
• Additional Dependencies: GTK4 (Debian 12+/Ubuntu 22.04+)

Notes

• Overclocking features need to be enabled per GPU model
• Recovery from bad overclocking has dedicated guides
