The nvidia-settings utility is a tool for configuring the NVIDIA Linux
graphics driver. It operates by communicating with the NVIDIA X driver,
querying and updating state as appropriate. This communication is done with
the NV-CONTROL X extension.
Values such as brightness and gamma, XVideo attributes, temperature, and
OpenGL settings can be queried and configured via nvidia-settings.
When nvidia-settings starts, it reads the current settings from its
configuration file and sends those settings to the X server.
Then, it displays a graphical user interface (GUI) interface for configuring
the current settings. When nvidia-settings exits, it queries the current
settings from the X server and saves them to the configuration file.
