If I understand well the documentation, for keys to work I have to play with them in devd. I have not had the time to explore it. Setting values directly with sysctl between 0 and 100 do work, but do not change the LCD brightness. Funny enough, I can toggle between 49 and 51 with the Fn keys, no more, no less.

My S440 has a i3-4030U processor, a 128GB SSD, 4GB RAM and a ThinkPad TrackPoint, and it’s perfect for my limited roaming needs… but only under Windows, that’s it. Best regards, Juan
