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. (b) It also copies the indicated
file to
~/.local/share/color/icc/devices/display

dispwin -L

does (a).  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 am
confident they are doing what they should. 

Sorry, no idea.
