It doesn't appear to make any difference whether I enable it manually or
use the color management addon I found. In either
case,gfx.color_management.enabled
is set to true.
But to tell it about the display, you apparently need to modify
gfx.color_management.display_profile
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
data.
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.
