gummy
CLI screen manager for X11 that allows automatic and manual brightness/temperature adjustments, via backlight (currently only for embedded displays) and gamma. Multiple monitors are supported.
Automatic brightness is based on screen contents. Support for ambient light sensors is planned.
Disclaimer: this program is still in development! You are welcome and encouraged to submit bug reports, suggestions and pull requests.
