I have switched from Datacolor Spyder 3 to X-Rite I1 Display Pro. Knowing that the support for the latter was added more recently than for Spyder 3, I have checked the installed software versions, i.e. Argyll CMS and dispcalGUI. I have found that installed dispcalGUI version is 0.9.9.1, by accessing the About dialog. Here I have an issue: the installed version is not listed by the equo command and no package manager finds it installed. Everything seems up to date. Sould I try to install dispcalGUI from the repo (18.104.22.168), over the existing one?
