LACT

What LACT is

LACT, the Linux GPU Configuration And Monitoring Tool, lets users control and monitor AMD, Nvidia, or Intel GPUs on Linux. It reports details including VBIOS, VRAM, hardware units, Resizable BAR status, and Vulkan features, and provides historical charts for power, thermals, and frequency. Users can check throttling information and export monitoring data as CSV. Available controls include power caps, AMD power states, clock settings, and custom fan curves for AMD and Nvidia GPUs. Undervolting uses voltage offsets for AMD and VF curves for Nvidia. Profiles can activate based on running processes or gamemode status. A system service handles configuration independently of a graphical session and can run headless from a configuration file. LACT includes an OpenTelemetry metrics exporter and a JSON API over a Unix socket or TCP. The TCP listener is disabled by default; remote TCP management has no authentication or encryption. Installation options include packages for several Linux distributions, Flatpak, and a Docker service-only setup. Available controls vary by GPU generation, driver, and hardware.
