DDCI

[SL-RU]

Hello!

There are plans to add direct DDCI support? There are ideas how to implement it?

Use the kernel module (see #76)
Though I didn't manage to get it working on my desktop with nvidia tbh :)

Same, even on NixOS AMD (though, probably an different issue; see https://bbs.archlinux.org/viewtopic.php?id=282805).

For the time being, I just use ddcutil, i2c and some udev rules for it.
