Purpose: nvcontrol is an NVIDIA GPU settings manager for Linux designed for Wayland.
Controls: It provides digital vibrance, display color controls, VRR/G-SYNC, HDR, overclocking, fan control, and power management.
Interfaces: The project includes a terminal dashboard and a GUI application.
Compositors: It lists KDE Plasma, GNOME, Hyprland, Sway, and Pop!_OS COSMIC as supported compositors.
AI diagnostics: Read-only diagnostics cover CUDA, Ollama, local AI/ML workload fit, and environment setup.
GPU support: The project lists RTX 50, 40, 30, and 20 series plus GTX 16 and 10 series, with support varying by driver and hardware.
Driver requirements: The README says matching NVIDIA open modules and userland are required and recommends Linux kernel 6.6 or later.
Driver compatibility: The driver guide identifies NVIDIA open driver 610 as the current primary target and directs users of 590 and earlier to an older vibrance-compatible build.
Support: The CLI provides diagnostics and support bundle workflows, including options to redact paths and identifiers.
Security and license: The repository provides the software under the MIT License, whose text says it is supplied without warranty.
Experimental controls: The README warns that overclocking and voltage modification are experimental and may cause instability or hardware damage.
Distribution: Installation instructions cover Arch Linux, Fedora/Nobara, Pop!_OS, Debian/Ubuntu, and building from source.
