It doesn't appear to make any difference whether I enable it manually or
use the color management addon I found.  In either
is set to true.

But to tell it about the display, you apparently need to modify
to give it the value the search path for the profile.   It doesn't seem to
matter whether I do that manually using about:config or by choosing
preferences to set the display.   The addon says that if you leave
that blank, it uses the `system' default.   But there is a clear
difference in what you see if the string is specified or if it isn't.

Just to confuse matters more, it shows up (different shades of) yellow
no matter what I do, including not loading the LUT with the calibration

I can't imagine how Fedora 9 Linux might differ from Mandriva.  I am
using X11 as provided by a fairly current version of xorg, although it
is hard to specify a version since it consists of so many packages.
