This issue has been brought up on this forum before: major Linux distributions are dropping Python 2 support and thus no longer support displaycal. And it’s understandable that it will take some time to port displaycal to Python 3.
What I wonder is: How complicated would it be to create an AppImage with displaycal, Python 2 and the necessary Python 2 libraries (such as wxgtk) that could work on any distribution thanks to the self-contained nature of AppImages? This would at least be a feasible workaround for the current compatibility issues.
Another alternative could be a Linux USB stick/CD-ROM boot image with displaycal (for example, based on Debian 10). Does anyone one whether such a bootable distribution with displaycal included does already exist?2021-04-30 at 15:52 #29842
I agree with you, an Appimage would be just great ! This would allow Linux users to enjoy Displaycal without having to port it to Python3 (at least not in a hurry). Plus it may be simpler to release than 10+ different Linux package formats.
For those seeking an immediate solution, there’s an (unofficial) Flatpak package on Flathub. Flatpak is available on most Linux distributions, and installing a new app is pretty straightforward.
I just tested it on Debian 11 Bullseye and it works great. The flatpak comes with every library necessary, I didn’t need to install any dependency, not even Argyll. The only trick I had to use was to modify permissions for /dev/usb/00x/00x but that was already the case using the .deb package with Debian 10 and Ubuntu 20.04.
Hope this will help.2021-05-02 at 8:44 #29914
I just launched a calibration using flatpak install, and it worked like a charm. Thanks for pointing this procedure!
The question is: will the profile be automatically loaded at system startup, as it appears to be in a folder local to flatpak? Is the loader installed system-wide?

To be more precise, I just want the LUT 1D to be loaded in the video card at system startup…2021-05-05 at 22:40 #30033
Sorry, I’m new to DisplayCal and I don’t know how to load the “LUT 1D” in the video card at startup (I mean, even without Flatpak involved)… Is this a feature specific to dedicated graphics cards ? I’m currently on a laptop with an integrated Intel GPU.
All I know is that on Debian 11 / KDE Plasma desktop I had to manually add “Profile Loader” to run at startup. Without this trick the profile did not load, although I selected the option after the calibration.

I found the solution. Looking at the console while DisplayCAL install the profile, I can see it uses
dispwin, an ArgyllCMS utility:
/app/bin/dispwin -v -d1 -c -I 'SyncMaster #1 2021-05-01 20-16 2.2 F-S XYZLUT+MTX.icc'
So, I installed the
argylldebian package, and, as explained in the ArgyllCMS documentation, added this command in the
~/.config/autostartfile (I moved the profile in the
~/.color/icc/dir, for easiest access).
Hope this helps.2021-05-08 at 0:30 #30079
