[SOLVED] display calibration curve lost when i open a new konsole tab.

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
Kde color managment seems to be a thing of kde4, so anybody knows why does it happen or where should i look?

Thanks...

I remember there are gamma settings somewhere in KDE's settings program. Maybe that's overwriting the color table?

Thanks, nice idea, unfortunately even the gamma modified by the kde gamma tool is reset when i open konsole.

Silly, silly me.
It was my .bashrc that loaded nvidia-settings everytime, and nvidia-settings reset calibration vurves (long standing bug).
I should have checked with other terminals.

I solved that problem like this, with 'sed' deleting the lines about gamma before running the nvidia-settings tool:

# delete gamma settings out of the nvidia-settings config so that it won't overwrite a monitor color profile
sed --in-place '/^\[.*\]\/.*Gamma=.*$/d' ~/.nvidia-settings-rc
nvidia-settings --load-config-only

I have this in ~/.xprofile. That script gets loaded only once when the desktop starts up, not every time a terminal window opens like ~/.bashrc.

Thanks, it works one time, but it needs to be done every time one opens the nvidia control panel.
Anyway, i found that keeping redshift loaded after loading the altered lut with the following in ~/.config/redshift/redshift.conf

[randr]
    preserve=1

...restores the correct lut every couple of seconds.
