    Hello!

    When creating a colorimeter correction with colormunki photo, displaycal asks to set the instrument in self-calibration position. When I do this and click continue, the same popup window then appears, asking the same question. I tried all dial positions on the instrument, but the same popup keeps appearing, never going past this point. Same happens when I try ‘self-calibration’ from the tools/instrument menu.

    This is in xubuntu 18.04 / displaycal 3.8.9.3. On my windows computer, it does seem to work correctly. I tried to get it to work on linux virtualbox with win 10 guest, but there the colormunki isn’t detected by displaycal (but it is working with the xrite software).

    Any suggestions what I could try on linux to make it work?

    thnx

    Hello,

    I just tried again a couple of times, and then it worked. I was able to create the correction and upload. But.. now I tried again and have the same problem. Dont know if this is due to a fault in the instrument. Swapping the usb cable or reconnecting the device didn’t work….

    hi David

    thnx for following up! No. It worked occasionally and I wasn’t able to narrow down the bug. I did manage to make the colorimeter corrections I needed, and havent looked at the problem after that..

    Hi Jos,

    here’s my theory: there’s a sensor in there that tells the instrument what position it is in. It is working alright when I set it to cal and then plug it in. But when I have to turn it to measure and then back to self-cal it doesn’t work. I used to work sometimes before, but now it doesn’t work at all.

    Best, David

    hi David

    hm yes now you mention it, if I remember correctly I also tried that and it seemed to work a couple of times, but not all the time. Maybe there is a possibility to start displaycal in a debug mode or something ? (-v?)

    I’m almost certain this is a hardware problem. When I use xrite i1studio I can see that the probe is not registering it’s set to the cal mode. My guess is that there’s dirt in there or so… Haven’t found a way to open up the housing though.
    Best, David
