Do you have any idea what to look for in order to be able to calibrate
my screen under Qubes?

What I already tried:

- the standard gnome color management tools runned in (sys-usb)
But it is complaining that there is no display to calibrate.

running the same calibration software directly complains about there is
no colord available (masked)

(gcm-calibrate:1459): Gcm-WARNING **: failed to connect to colord: Error
calling StartServiceByName for org.freedesktop.ColorManager:
GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit colord.service is

- diplayCal is happy with the dummy display seen by the AppVM, and do
not depend on colord - but it fails on some X calls(?)

Debug: window wxComboBox(0x561c58c3a230, ) lost focus even though it
didn't have it
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  42 (X_SetInputFocus)

Or I should connect the calibration device to dom0 and start the
calibration from dom0?
(Also noted that there is no colord running, so I may have to apply the
profile viea diplaycal cli)
