Arch Linux User Repository

Using i3, I can't seem to open any models. Attempting to open files doesn't seem to do anything.

On startup, I get the following logs in the console:

PyInstaller/loader/pyimod02_importers.py:499: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses
Cyclic dependency detected between "file:///opt/cura5/share/cura/resources/qml/Actions.qml" and "file:///opt/cura5/share/cura/resources/qml/Actions.qml"
QQmlEngine::setContextForObject(): Object already has a QQmlContext

But that's about it. Attempting to Open File(s)... doesn't log anything. It just does nothing.

QT_QPA_PLATFORMTHEME controls the dialogs that Qt uses. xdgdesktopportal tries to use native dialogs, while gtk3 forces the use of GTK3 dialogs. If previously used paths are not recalled, there may be a problem with desktop configuration, like file history is disabled.

Rather than editing the script, the platform theme can be changed with a command-line parameter. This overrides the environment variable.

cura -platformtheme gtk3

It's probably best to leave the script in the package alone. Changing it could cause problems for other users, and most desktop environments provide an easy way to edit the app menu.

Just in case anyone has the problem with cura not opening any file dialogs at all, changing QT_QPA_PLATFORMTHEME to gtk3 in /opt/ultimaker-cura/AppRun solved it for me.

@xiota
That did the trick! Thank you so much for the hint!
With that being said, I now had to change the desktop entry for how I launch Cura (using rofi).
Here's what I ended up doing and worked for me:

• /opt/ultimaker-cura/AppRun: QT_QPA_PLATFORMTHEME change from xdgdesktopportal to gtk3

• /usr/share/applications/cura.desktop: change Exec to Exec=/opt/ultimaker-cura/AppRun %F

I hope this information will help with fixing the issue without resorting to clunky solutions :)

@johnride: Yeah, as @xiota mentioned, base-devel is typically assumed to be installed when you're building packages. I'd recommend running pacman -S --needed base-devel right now to pull everything from there in.

@wallace11: Hey, I don't think the save or open dialogues have ever remembered the last path for me, are you saying it's done that correctly for you at one point or another? I just tested the installed package as well as the pure AppImage and got the same results in both cases (no memory). EDIT: Not having ever worked for me includes the old official package.

@wallace11 Does changing QT_QPA_PLATFORMTHEME=xdgdesktopportal to QT_QPA_PLATFORMTHEME=gtk3 in the AppRun make a difference? If not, can you comment out each export line one by one until you find which one may be causing problems?

AppRun patch has given me quite some headache because when saving to disk it would not remember the last path and would not insert the file name - it's completely empty. I downgraded to pkgver 2 for now until either me or someone else finds a solution.

For reference, I'm on a DE (bspwm) and got both xdg-desktop-portal and xdg-desktop-portal-gtk installed. The former got a couple of updates recently and I tried all versions with no success.

patch is part of base-devel. I've never seen a package with anything from base-devel included as a build dependency.

patch should be added as a build dependency. Just had a build fail because it was not installed.

Thanks for the package otherwise!

Hi,

to get cura5 to run correctly in KDE + Wayland the last line of the script /user/bin/cura5 should be as follows:

QT_QPA_PLATFORM=xcb LD_PRELOAD=/usr/lib/libstdc++.so.6 QT_QPA_PLATFORMTHEME=xdgdesktopportal QT_QPA_PLATAFORM=xdgdesktopportal ./Ultimaker-Cura $@

After the above is applied Cura5 works as espected. If run from terminal, the below warnings are outputted:

PyInstaller/loader/pyimod02_importers.py:499: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses Cyclic dependency detected between "file:///opt/cura5/share/cura/resources/qml/Actions.qml" and "file:///opt/cura5/share/cura/resources/qml/Actions.qml" QQmlEngine::setContextForObject(): Object already has a QQmlContext
