right, but I'm a bit confused as to why you are listing eDP1 along
with the Screen 0 _ICC_PROFILE root window atom, since eDP1
looks like an XRANDR output name. Is that output on Screen 0 ?
(i.e. what does the eDP1 XRANDR _ICC_PROFILE property hold ?)

eDP1 probably *was* Screen 0, because it's the laptop's main monitor and I always disable it when I attach my external dual monitor setup.

$ dispwin -?
[...]
-d n[,m] Choose the display n from the following list (default 1)
Optionally choose different display m for Video LUT access
1 = 'Monitor 1, Output DP1-8 at 0, 0, width 2560, height 1440'
2 = 'Monitor 2, Output DP1-1 at 2560, 0, width 2560, height 1440'

Unfortunately I don't know how to get the eDP1 XRANDR _ICC_PROFILE property you asked for.

Could you compile and test
<http://www.argyllcms.com/Argyll_dev_src.zip>,
to see if this behaves any differently ?
(Although I suspect this won't solve your problem.)

With that version though, could you set the
ARGYLL_IGNORE_COLORD environment variable to "true",
and then then re-install the profile (dispwin -I etc.)
and see if that looks any different.

Before:
$ darktable-cmstest
darktable-cmstest version 2.2.0rc0+90~g7a24993
this executable was built with colord support enabled
darktable itself was built with colord support enabled

The contents of the
ucmm color.jcnf file could also then be revealing.
(See <http://www.argyllcms.com/doc/ucmm.html> for where to
find that file.)

It would be good to compare that to what's in colord's database
(I'm not sure how you do that though - perhaps you can ask Richard.)

Sure thing. The easiest thing to do is "colormgr dump" or doing
sqlite3 /var/lib/colord/mapping.db and then dumping everything there.
