[ddccontrol-users] Dell 4100MP projector

[C. A. M. <and...@vi...>]

Hi,

I was trying to see if I could get DDC/CI to work with several Dell 
4100MP projectors. Unfortunately, it looks like they do not support 
DDC/CI. I know my video card setup works fine with DDC/CI at controlling 
Dell 1907FP monitors. I will post the relevant information here, and 
maybe the experts can confirm my suspicions, or point me in the right 
direction to get things working with this projector:

DDC/CI at pci:04:00.0-1 is unusable (-1).
If your graphics card need it, please check all the required kernel 
modules are loaded (i2c-dev, and your framebuffer driver).
