Applying the color profile is half of the job, next part is to provide

Here I'm stuck a bit because I would need to make the DUMMY display
(provided by Qubes) as a color managed device. Then I would be able to
"apply" the same profile. Here the apply only would means that colord
can provide that profile to the colord aware applications. (Firefox,
Eog, Darktable in my case)
@Marek: Any idea how to achieve this?
Maybe our dummy X driver should provide some properties/capabilities for
this? Adding some placeholder functions shouldn't be a problem (if that
would be enough) - as soon as someone would find which one.
Without this I still getting better colors overall - but the real color
management is only achievable if the apps are using the same profile.
I think this assertion should be verified before using time and
resources on this. At best, it seems like a requirement for a
rarely-needed feature. Display calibration is a hardware driver issue
and I'm using it just fine with KDE in dom0. When I print, the color
gamut and cast matches what I see in the appVM window quite well.
I also think we should avoid pushing details that identify hardware into
domUs.
No doubt, calibration for /printers/ is something to be handled in
domUs, but that's because printer drivers operate there.

For now I can configure apps (at least Darktable for sure) to use my
color profile manually.
(BTW: I'm about to create a "color management in Qubes" documentation soon)
