So for me to install the latest intel drm and produce a driver diagnostic log is pointless. However, I've received enough bug reports from people who have tried to use ddcutil through a docking station that I'm pretty sure there's a problem. >From the original post on the intel-gfx list: > I'm not sure how best to go about reporting these issues. The usual bug > reporting mechanism asks for detailed information about a specific > system, which I don't have. What I do have is the ability to see a > pattern. > Because I2C communication is so fragile (dependencies on hardware > quirks, drivers, etc), ddcutil (which is written in C) has an extensive > subsystem devoted to remotely diagnosing user configurations.

That list thread led to the suggestion that I post a bug report despite the unavailability of detail. Hopefully I've categorized the bug properly, and this report will at least serve as a marker that there's a problem.
