LACT vs NVIDIA_OC Daemon

LACT is a free, MIT-licensed Linux tool for controlling and monitoring AMD, Nvidia, and Intel GPUs. It reports VBIOS, VRAM, hardware units, Resizable BAR status, and Vulkan features. Monitoring provides configurable historical charts for power, thermals, and frequency, plus throttling information and CSV export. Controls include power caps, AMD power states, GPU and VRAM clocks, and custom fan curves on AMD and Nvidia. Undervolting uses voltage offsets on AMD and VF curves on Nvidia. Profiles can activate according to running processes or gamemode status. A system service applies GPU configuration without depending on a graphical session and can run headless from a configuration file. LACT includes an OpenTelemetry metrics exporter and exposes a JSON API over a Unix socket or TCP. The TCP listener is disabled by default; remote TCP management has no authentication or encryption. Packages are listed for several Linux distributions, with Flatpak and Docker service-only options. Available controls vary by GPU generation, driver, and hardware.

NVIDIA_OC Daemon is a Linux daemon that applies NVIDIA GPU overclocking settings through NVML. It is intended for systems where X.Org Coolbits tools such as GreenWithEnvy or nvidia-settings are unavailable or undesirable, including Wayland setups. The daemon reads TOML settings from /etc/nvidia_oc/config for GPU clock offsets, memory clock offsets, and power limits, with controls available per device. On first run, it creates the configuration file from currently reported GPU settings. It watches /etc/nvidia_oc recursively and reloads changed configuration after a five-second debounce. Logs go to the terminal and to demon.log in the process working directory. The software requires Linux, a supported NVIDIA GPU, and a driver exposing NVML as libnvidia-ml.so. Building requires a Rust toolchain; creating configuration or applying settings requires root or equivalent permissions. Some laptop GPUs or driver and device combinations may not expose power-limit operations. The repository does not include a systemd unit. The project warns that overclocking and power-limit changes can crash systems, damage hardware, void warranties, or make a machine unbootable.
