    HDMI CEC sounds good, but i would like to know which device. The only device i know of does not seem to need a driver. But is is a tiny bit too cheap to try it

    Well, every HDMI enabled videocard _should_ in theory have a CEC port. True some (older) cards don't have this, but certainly newer ones do?

    The USB CEC device by pulse-eight is just a stopgap imo. Also there's some arduino devices+code for connecting to the CEC port.

    So maybe I'm missing something, but what exactly do you mean with 'which device'? If you meant that all hardware needs a kernel driver to supply the CEC bus, then I guess of course so. But once they have settled on the bus description, I'm sure those drivers will pop up quite fast.

    From what I understand, CEC is designed so that it can be handled by a separate controller on standby voltage, and is not "really" part of the HDMI protocol but rather is a separate protocol on the same connector. So I don't think we can assume that there's widespread video card support for it.
