The NVIDIA Accelerated Linux Graphics Driver brings accelerated 2D functionality and high-performance OpenGL support to Linux with the use of NVIDIA graphics processing units.

These drivers provide optimized hardware acceleration for OpenGL and X applications and support nearly all recent NVIDIA GPU products. The NVIDIA graphics driver uses a Unified Driver Architecture: the single graphics driver supports all modern NVIDIA GPUs.

The nvidia-settings utility is a tool for configuring the NVIDIA graphics driver. It operates by communicating with the NVIDIA X driver, querying and updating state as appropriate. This communication is done via the NV-CONTROL, GLX, XVideo, and RandR X extensions.

Values such as brightness and gamma, XVideo attributes, temperature, and OpenGL settings can be queried and configured via nvidia-settings.

You need the Nvidia proprietary driver. This is not a standalone application.
