Sorry for that, but i'm unable to solve this irritating issue.

I'm using KDE and I calibrated my monitor manually using caled from aur, and i've got a .cal file which i loat into the LUT with dispwin.
Unfortunately, as soon as i open konsole or open another konsole tab (the same happens with yakuake), the LUT is reset to the default values.
I already tried to kill colord, but this won't stop the issue.
Also, on another system this does not happen, so there have been some configuration i'm missing.
Still, kde color managment seems to be a thing of kde4, so anybody knows why does it happen or where should i look?

Thanks.
