The program itself works with a main screen (in my case laptop). The profile loader also works. I just felt like it took a little longer with Linux Mint compared to Windows. Unfortunately, when I wanted to calibrate an extended second screen, it stopped in the middle of the calibration. Fortunately, I was able to use my color profile and copy it into the color management, which I created under Windows with DisplayCal. Since it is a very important program to use accurate colors, I hope it can be fixed. I used an iDisplay Pro Plus.
