Thanks for reporting. This issue appears to be a special case. Unfortunately I have no means to test on such a card. Can you verify the ramps are correctly written?

I guess matrix handling is out of scope for xcalib. Xcalib works on single channel curves and is not crossing channels like matrices do. However I keep this request open,...

Below are two taskbar screenshots. One comes with a CIE*L invert ICC effect profile, white point setting to ~3000Kelvin and the ICC VCGT calibration applied in CompICC. The other screenshot...

@log69 In a 1D calibration world, the one xcalib works in, it is not possible doing 3D changes on colors, like you want with a 180° HSL space manipulation. A...

Handling of gamma is not managed inside X. Every client can mess with gamma without enough information. As these APIs are set in stone, there is no change to be...

> I think another good solution would be to get the same functionality with xcalib as with redshift/xflux/anything else? That might be possible, but is as well some work. (I've...

Currently the Oyranos CMS just takes a bunch of options from ~/.config/color/settings/openicc.json and applies them. The display profile is located in the _ICC_DEVICE PROFILE(_XXX) or _ICC_PROFILE(_XXX) atoms. That is indeed...

Indeed undoing a particular calibration state needs a notion of the stack. My take was to use **one** daemon at a time. It is then responsible to track that state....

Oyranos git uses now a separate daemon to keep the calibration curves + white point adjustments and possibly a effect working. xcalib is only used as a tool to load...

Would it help to avoid flicker, when xcalib accepts a profile without VCGT + gamma arguments (-gammacor XXX -red ...)? Thus xcalib -c is not needed. (At the moment only...
