@RyuConnor can you copy&paste the terminal output, I don't see where this error is generated exactly.

RyuConnor · 2023-07-01T22:10:52Z

You'll have to tell me how to do that. The error does not have a log attached.

DisplayCal Error

Hey @RyuConnor, maybe you start displaycal from some kind of menu, start displaycal instead from a terminal via displaycal. If you do so you will get ouput in that terminal.

RyuConnor · 2023-12-09T04:07:15Z

Is there a work around for this bug until a new version with this fix is released? I haven't been able to calibrate my laptop for two years due to this error. :(

p5k369 · 2024-01-06T20:03:35Z

Hey @RyuConnor,
sorry for the late reply. Are you installing displaycal via arch package manager? Please note that there is a newer version which should contain that fix. You also can clone the develop branch and run displaycal from there.

RyuConnor · 2024-01-15T19:39:17Z

Hello @p5k369. Thank you for helping me. Unfortunately, despite the fact that the Arch Maintainer of DisplayCal built version 3.9.11 long after the original release date, they did not include this fix as part of their build.

The Maintainer is unlikely to update the official package again until 3.9.12 gets pushed and even then it might take a few months for that to happen based on past precedent.

I have tried my hand at manually updating the package with help from the ArchWiki. It has not gone well. I am not ashamed to admit, that I'm out of my depth.

p5k369 · 2024-01-16T15:39:36Z

Hey @RyuConnor,
we could ping the maintainer for a release but that might not help you immediatly.
You could however get displaycal working in a virtual environment as described here: https://github.com/eoyilmaz/displaycal-py3?tab=readme-ov-file#how-to-install
You're on linux, so you will get it running. Also I'm willing to support you until you get it working if you wish.

eoyilmaz · 2024-03-10T15:49:12Z

I'm going to release 3.9.12 soon, fyi...

eoyilmaz · 2024-03-19T22:45:19Z

3.9.12 is released please try it.

RyuConnor · 2024-04-01T00:05:22Z

It still crashes at the end.
