Please use the bug report format and supply steps to reproduce.

[marillat]

Launch displaycal Click on the Calibrate & profile buton displaycal crash

[eoyilmaz]

You should start from how did you install DisplayCAL.

[marillat]

Why ? displaycal is installed from the Debian package.

[eoyilmaz]

It really depends on how you have installed. Let me check now if I can reproduce this.

[marillat]

displaycal has been always working with files installed like this

https://packages.debian.org/sid/amd64/displaycal/filelist

[eoyilmaz]

Yes, but sometimes, unfortunately, we introduce bugs, and knowing the way you installed helps to pinpoint the bug.

[marillat]

Yes, I do the same (sometimes) with the Debian packaging.

I know why this is happening. 6c00bfb changed the pydir and DisplayCAL.display_cal.MainFrame.start_measurement_subprocess() is referencing that path, which now shows the parent of the previous value and this only effects Linux systems as MacOS and Windows are using a different code path to show the dialog.

Should be easy to fix.

[eoyilmaz]

ah no, my mistake, the pydir is still pointing to the same folder. But that script should import DisplayCAL.wxMeasureFrame and not wxMeasureFrame directly.

[eoyilmaz]

I'm using a virtualbox image for Debian 12, but I can't seem to be able to build and install wxPython. I'll try with Ubuntu 24.10 which was building okay. I should hit to the same error, if I'm able to start the calibration with the virtual monitor at all.

[eoyilmaz]

hmm... ArgyllCMS executables are not working under aarch64 🤷‍♂️

let me do it remotely then, I'll update the code, and I'll be appriciated if you can try running it.

[eoyilmaz]

@marillat can you try running the following to build and run from source:

cd ~
sudo apt-get install build-essential dbus libglib2.0-dev pkg-config libgtk-3-dev libxxf86vm-dev python3-dev python3-venv
git clone https://www.github.com/eoyilmaz/displaycal-py3
cd displaycal-py3
git fetch --all
git checkout 415-fail-to-open-calibrate-window
SYSTEM_PYTHON=python3 python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt -r requirements-dev.txt
python -m build
pip install dist/DisplayCAL-3.9.*.whl

and you should now be able to run:

python -m DisplayCAL

and for any consequent runs on a new terminal you can run the following:

cd ~/displaycal-py3
source .venv/bin/activate
python -m DisplayCAL

As I'm saying before, I'm the Debian maintainer and we don't use python virtual environment to build the package but pybuild.

Anyway commit https://github.com/eoyilmaz/displaycal-py3/commit/90b7192300f991ff7d6cbdac7c7ba5c1094ae38d fix this issue.

oh sorry, my bad, didn't understand you are the Debian maintainer, cool!

I'm glad that the problem is solved. I'll do a new release this week, I'll let you know 👍

[marillat]

I've already uploaded a new package 3.9.13-4 not yet available in unstable.

Thanks for your work and fast bug fixes.

[eoyilmaz]

3.9.14 is released
