A mysterious monitor profile, "NEC-LCD2190UXi-85414002YA_edid.icc",
has appeared on my computer. I used icctoxml to examine the profile.
It looks like it was created back in March, 2012, shortly after I
installed OpenSuse 12.1 on my computer (was previously running Debian
Sid).
Such profiles are typical generated by Oyranos if it sees no profile
assigned to a connected monitor device. It is a fallback profile, which
is generated from EDID. Oyranos does that without asking to serve naive
users. You can easily override that profile.
This mystery monitor profile seems to have been pulled from the
monitor itself, which I didn't even know was possible. I would have
remained blissfully unaware of its existence, except recently (perhaps
yesterday) it managed to get itself installed as my system monitor
profile.
Yes. Oyranos sets up a monitor profile automatically.
I don't use a system monitor profile. I do use a monitor profile that
I made using Argyllcms. My own monitor profile has completely
different primaries and tone curves, not to mention a different name
and location on my computer.
Specs are designed to use the _ICC_PROFILE(_xxx) atom. You should be
able to use Argyll's dispwin or Oyranos' oyranos-monitor tools to setup
your custom profile for your monitor. Then your profile should be used
instead. I assume that is what you intented.
Also, every time I restart my computer, a video-lut gets loaded. I'm
guessing the lut goes with the mystery profile, but it's just a guess.
I can use "dispwin linear.cal" to replace the unwanted video-lut, but
I would really rather it didn't get loaded at all.
The from EDID fall back profiles contain no VCGT curves (alias
video-lut). You can create profiles without such calibration data. Read
your profilers documentation to find out how to do so.
Here are the first few lines from the mystery video-lut, saved using
"dispwin -s mystery-video-lut.cal":
KEYWORD "RGB_I"

And here is are the equivalent lines from "linear.cal":

I'm really hoping someone can shed some light on this unwanted profile
and/or video-lut. I got rid of the monitor profile (it no longer
installs itself) by removing it from the ./local/share/color/device
folder (don't know how it got there, didn't even know there was such a
folder). But I can't get the video-lut to stop loading.
That path is the standard OpenICC path for user installed ICC profiles.
