You can create a config file at $XDG_CONFIG_HOME/calibright/config.toml with a [global] section as well as separate sections for each display.
All of the sections allow the same parameters:
Key | Value | Default
-----------------------------|---------------------------------------------------------------------------------------------------|---------
root_scaling | Scaling exponent reciprocal (ie. root) Allows values from 0.1 to 10.0 | 1.0
ddcci_sleep_multiplier | See ddcutil documentation | 1.0
ddcci_max_tries_write_read | The maximum number of times to attempt writing to or reading from a ddcci monitor | 10
calibration | A pair of floats representing the the min and max brightness | [0.0, 100.0]
A simple example config could look like:
```toml [global] ddccisleepmultiplier = 0.1
[ddcci6] calibration = [0, 90]
[ddcci7] calibration = [10, 80] ```
