Description
Read and write EDID data over an I2C bus.
To install udev rules, you also have to add services.udev.packages = [ pkgs.rwedid ] into your configuration. Additionally you will also have to create the i2c group, on NixOS this can be done using users.groups.i2c = {};. And you will have to load i2c-dev kernel module, for that add `boot.initrd.availableKernelModules = [ i2c-dev ] to your config.
