Facts

Purpose: LACT lets users control AMD, Nvidia, or Intel GPUs on Linux.github.com · 4 Oct 2026
GPU information: It reports GPU details such as VBIOS, VRAM, hardware units, Resizable BAR status, and Vulkan features.github.com · 4 Oct 2026
Monitoring: It provides configurable historical charts for power, thermals, and frequency, throttling information, and CSV export.github.com · 4 Oct 2026
Configuration: It supports power caps, AMD power states, custom fan curves on AMD and Nvidia, and GPU or VRAM clock configuration.github.com · 4 Oct 2026
Undervolting: GPU undervolting is available through voltage offsets on AMD and VF curves on Nvidia.github.com · 4 Oct 2026
Profiles: Profiles can activate automatically based on running processes or gamemode status.github.com · 4 Oct 2026
Metrics integration: LACT includes an OpenTelemetry metrics exporter.github.com · 4 Oct 2026
Background service: GPU configuration runs through a system service that does not depend on a graphical session, and the service can run headless from a config file.github.com · 4 Oct 2026
Hardware support: The project documents AMD, Nvidia, and Intel GPU support, with available controls varying by GPU generation, driver, and hardware.github.com · 4 Oct 2026
Installation: The project lists packages or installation options for distributions including Arch, Debian/Ubuntu, Fedora, Gentoo, openSUSE, NixOS, and Solus, plus Flatpak and Docker service-only installation.github.com · 4 Oct 2026
API: The daemon exposes a JSON API over a Unix socket or TCP, and the TCP listener is disabled by default for security reasons.github.com · 4 Oct 2026
Remote management security: The README says remote TCP management has no authentication or encryption and should be used only on trusted networks or with appropriate firewall rules.github.com · 4 Oct 2026
Configuration safeguard: API configuration changes require confirmation or are automatically reverted after a short period, five seconds by default.github.com · 4 Oct 2026
Maker: The repository identifies Ilya Zlobintsev as its owner and describes LACT as a Linux GPU Configuration And Monitoring Tool.github.com · 4 Oct 2026
