If I start darktable everything is OK, but if I want to edit a picture the color of the picture are displayed wrong.

darktable -d opencl or
darktable --disable-opencl
makes no difference

Have anyone a Idea how to solve this

Sample?

You may also want to check the output color profile module, and try setting those all to sRGB, to exclude a broken (potentially auto assigned) display profile.

#3 Updated by Davin Geiger about 5 years ago

Ah okay, thank you.

If i change the "display profile" from "system display profile" to "sRGB" it works.

#4 Updated by Pascal de Bruijn about 5 years ago

That means you have a horribly broken display profile setup in your system. So this isn't a darktable bug.

Can you run darktable-cmstest and paste it's output back here?

Also, please check this:
ls -l ~/.local/share/icc/edid*icc

If that returns anything, could you attach that ICC file for us to inspect?

Better check your system setup
 - some monitors reported different profiles
You may experience inconsistent color rendition between color managed applications

ls -l ~/.local/share/icc/edid*icc

I have created my display profiles with dispcalGUI

The last .icc profile is this one which I created with dispcalGUI

  • Status changed from New to Closed: invalid

So that dispcalGUI profile seems quite severely broken.

And creating XYZLUT profiles is generally not a good idea anyhow.

I'd highly recommend try using GNOME Color Manager or doing it manually:
