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:
[global]
ddcci_sleep_multiplier = 0.1
[ddcci6]
calibration = [0, 90]
[ddcci7]
calibration = [10, 80]
