Under Fedora 9 Linux, if I understand correctly, dispwin -I cal/profile (a) loads the designated calibration into the video LUT and sets the ICC atom in X to the appropriate profile.

But my ~/.local/share/color/icc/devices/display directory contains copies of every profile I have used.
Right. They'll stay there until you uninstall them using -U
How does dispwin -L know which one of them to use?
Because it's recorded the association between the profile and the display in the file ~/.config/color.jcnf See <http://www.argyllcms.com/doc/ucmm.html> It's not likely anything other than Argyll uses this convention though. Applications should really just be looking for the appropriate atom: <http://www.burtonini.com/computing/x-icc-profiles-spec-0.2.html> that dispwin -L will create.
I ask this question because it seems clear that eye of gnome and gimp are showing different things although both supposedly use the calibration/profiling information, and I am trying to figure out why. I believe that eog should be using color management because I checked the source code. gimp and inkscape show exactly the same thing so I amconfident they are doing what they should.
Sorry, no idea. Graeme Gill.
