LACT is a Linux GPU control application for AMD, Nvidia, and Intel graphics hardware.
It provides a graphical interface for changing GPU settings and monitoring behaviour, while a background system service handles configuration independently of a graphical session. The service can also be used with a config file in headless environments.
This is free and open source software.
