    It got fixed!

    export QT_QPA_PLATFORM=xcb

    did the trick. But I think Ubuntu noticed this automatically, because I eventually got at the same 'hanging' stage as the first time. After running the calibration a pop up comes up saying 'unknown - 'cover image' ready'. There is nothing like a commit button or similar.

    I was working on a pretty small screen so it could be that I've missed info from the terminal. I eventually just pressed space randomly and that basically was the key, from there on I could accept every step/image with hitting 'space' and got eventually the green finish screen.

    Thanks again. If needed I could send some photographs from the process.

  • lovro Thank you for your suggestion.

    It doesn't seem to work. Could it be a reason that I'm working from a virtual environment?

    Also, I'm currently running the script:

    python3 calibrate.py -s [SQUARE_SIZE_IN_CM] --board [BOARD] -nx [squaresX] -ny [squaresY] -m process

    Since I've taken all the photographs already, that went fine, but the calibration stage gives problems. Or do I have to go through a clean calibration session and using your 'export' suggestion?

  • Dear,

    I've gone through the steps of calibrating the OAK D PRO using Linux Ubuntu 24.04.1 LTS. It went fine up until the INTRINSIC CALIBRATION, the 3 images of the cameras pop up and then it stays there forever.

    I do get a warning saying:

    Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway
