Yup, this has been done by gnome-color-manager for about 2 releases now (1 year+), and colord-kde for a few months. > I'm really hoping someone can shed some light on this unwanted profile > and/or video-lut.

But I can't get the video-lut to stop loading. The so called "auto-edid" profile doesn't have any VCGT data, and so if it's being used by default then then VCGT is cleared to a unity gamma ramp as if there was no profile set at all. Are you loading a VCGT before gnome starts somehow? Richard.
