Re: [darktable-user] Laptop screen calibration
Thanks sofar, István. I've been experimenting a lot this week with varying results. I'll get back to you on this topic later, with hopefully a bit more understanding from my part on how the various bits correlate.

Not directly, because a part of the profile is applied to the video LUT which operates on the whole screen. An AB comparison would require you to reset the video LUT, too.

Re: [darktable-user] Laptop screen calibration
Excellent. I did install the profile via the openSUSE system setting screen. So that should take care of it. (darktable-cmstest also reports the new profile. So I think this confirms it). That leaves me with two follow up questions: 1. I can forget about the instructions for copying the profile to ~/.config/darktable/color/out ? 2. Is there an easy way to see the factual difference between how a photo looks now compared to what it was before? Thanks again!

If you have installed the color profile properly*, you do not need to do anything more with darktable, because it will obtain and use it automatically. * there is a color management daemon running, like gcm, xiccd or similar, which configures the LUT of your hardware and provides the profile to applications like darktable, for example by setting the xatom variable accordingly.

[darktable-user] Laptop screen calibration
I'm a bit lost. Last week I've purchased a ColorHug2 to profile my laptop screen. I've RTFM of the ColorHug2 and now I'm in proud possession of an .icc profile for my latop screen. But I don't know what to do next. I've read the Darktable manual. But there just too many references to color management. Agreed, I'm a total novice on that topic.
