The same thing happens when trying to end a session with the logout greeter.

As a workaround, you can install the package for the Breeze qqc2 style. Thanks, I ran into a similar issue preparing for a Slackware release of Plasma6 Beta2: logout from the desktop stalled (the logout greeter would not appear) and I would be forced to logon remotely and change the runlevel, or else forcibly reboot. The error messages in SDDM's xorg and wailand logs brought me to this bug report and indeed I did not include a qqc2-breeze-style package assuming it would be used by Plasma Mobile only. I am going to add that package now if it is a workaround to the bug. Thanks for fixing it in git. |
SUMMARY I upgraded Arch Linux from Beta 1 to Beta 2. I will keep an eye on this bug over the next several days and close this bug if it resolves itself due to packaging issues. Might be related to upgrading to Qt 6.7? This is a regression from Beta 1 on the same system. STEPS TO REPRODUCE 1. Allow the screen to try to lock itself, or launch /usr/lib/kscreenlocker_greet from the terminal OBSERVED RESULT An opaque full screen window blocks the screen, but no UI elements appear on it. If launched from the terminal, the following is printed: QQmlComponent: Component is not ready kf.plasma.quick: "file:///usr/share/plasma/wallpapers/org.kde.image/contents/ui/main.qml" "Error loading QML file.\n53: Type ImageStackView unavailable\nmodule \"org.kde.breeze\" is not installed\n" QQmlComponent: Component is not ready kf.plasma.quick: "file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreen.qml" "Error loading QML file.\n33: Type LockScreenUi unavailable\nmodule \"org.kde.breeze\" is not installed\n" kscreenlocker_greet: Failed to load lockscreen QML, falling back to built-in locker kscreenlocker_greet: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreen.qml:33:5: Type LockScreenUi unavailable LockScreenUi { ^ kscreenlocker_greet: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml: module "org.kde.breeze" is not installed KDeclarativeMouseEvent is both anonymous and named KDeclarativeWheelEvent is both anonymous and named QQmlComponent: Component is not ready kf.plasma.quick: "qrc:/fallbacktheme/LockScreen.qml" "Error loading QML file.\nmodule \"org.kde.breeze\" is not installed\n" kscreenlocker_greet: Wallpaper needs to be a QtQuick Item EXPECTED RESULT screenlocker opens normally SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.91.0 KDE Frameworks Version: 5.247.0 Qt Version: 6.7.0beta1-2 Kernel Version: 6.6.7-arch1-1 (64-bit) Graphics Platform: Wayland
