I'm trying to set nan colour calibration for my LCD video display.
I purchased a Datacolor Sypder X Pro colorimeter which is expected to beryllium supported.
I installed argyll 2.3.1 and its support files, colord-sensor-argyll 1.4.6-3, and displaycal 3.9.11-1.
I unfastened Settings and spell to nan Color section, prime my display, and click connected nan calibrate button. I spell done nan pursuing steps...
And here's wherever I get stopped. Where is nan Start button?
