I'm looking into writing an app to be able to control display
controls via DDC - DDC2ci, or SoftDDC
I've been going through the 4.4.0 sourcebase, and while I have seen
numerous references on how to implement DDC control at the driver level
over the i2c bus.
Is there an API, or server extension which exposes this interface?
Mac OSX 10.3 exposes the I2C bus at the user level via a
IOI2CSendRequest command.
Is there an equivalent for X?
Jablonka Ivan [EMAIL PROTECTED] was asking about ddc/ci recently.
There is as yet no intereface in XFree86 to use DDC for control
(just the XFree86_DDC_EDID1_RAWDATA X property which makes the
EDID information available).
Some linux kernel frame-buffer modules may make DDC available
through the kernel I2C machanisms.
Do you have DDC2ci specs ? I'd be interested in seeing what
we would need to put into a control API.
(Google shows no hits for SoftDDC).
