Hi,

According to the settings (or from what I understand) darktable chooses the
system display profile by either of the two methods:
 1. xatom
 2. colord

My understanding is if "all" is selected in the settings, darktable tries to
gather info by trying all of the two methods.

I use Oyranos in combination with Kolor-Manager of KDE with KDE as the
environment and when I am using a simple displaymanager/windowmanager (i.e.
slim with awesome or sawfish) then xicc is used to load the profile.
Nevertheless in all cases system is color managed.

So this means for darktable the only available information is coming from the
xatoms as only libcolord is installed. Using xprop to get the info regarding
the _ICC_PROFILE here is the outcome:

xprop -display :0.0 -len 14 -root _ICC_PROFILE
_ICC_PROFILE(CARDINAL) = 

But when I use the _ICC_DEVICE_PROFILE the information is there:

xprop -display :0.0 -len 14 -root _ICC_DEVICE_PROFILE
_ICC_DEVICE_PROFILE(CARDINAL) = 0, 0, 79, 12, 97, 114, 103, 108, 2, 32, 0, 0, 
109, 110

There is a slight difference in output between selecting "system display
profile" and the specific profile, which is by the way XYZ Matrix.

So by using the xatom option does darktable get the information correctly or
is there something missing along the line.

Thanks

Togan
