Did you try installing to the user or as system wide (which should require root access)?

I had a problem where Xcalib would work but dispwin could not access the VCGT. It seemed to work after using the ARGYLL_IGNORE_XRANDR1_2 environment variable. It is mentioned here:

I only see a wasteland of text with content that is incomprehensible to me. How does this help me if I have exactly the same error?

Unless you can use ArgyllCMS yourself by script or console, the most you can do is submit an issue requesting that DisplayCal include the already existing option from ArgyllCMS. Do what you can reasonably do and then waste no more energy...

And keep in mind this is only a potential solution, it's not guaranteed to solve your problem.

I assume that I cannot create a profile under Windows with the Datacolor software that I can then import in Ubuntu (Settings->Colours)?

If you are running DisplayCAL through a terminal run it like this:

ARGYLL_IGNORE_XRANDR1_2=yes displaycal

if this works for you than you can update ~/.bashrc with:

export ARGYLL_IGNORE_XRANDR1_2=yes
