Can those seeing this bug please install the read-edid package (sudo apt-get install read-edid) and then post the results of running:
get-edid | read-edid
I've read that ddcprobe only handles edid 1.0 data, and returns edidfail in other cases. get-edid is used by other distros, and supposedly handles versions of edid above 1.0. Your data could help confirm or disprove this.
