--- Comment #3 from [email protected] --- The core files are gone. They lived on the root subvolume, and restoring the pre-upgrade snapshot removed them. systemd-coredump still has the journal stack from the 2026-10-19 16:46:34 CEST crash (plasmashell pid 1554). The same stack repeats for the restarts a second later, and again on a later boot at 16:51. Immediately before the crash, plasmashell logged: The backend got an unknown wallpaper provider type. The wallpaper will now fall back to the default. QQmlComponent: Component is not ready Journal stack, thread 1554, not a debug-symbol backtrace: #0 QQuickItem::setParentItem(QQuickItem*) libQt6Quick.so.6 #1 PlasmaQuick::ContainmentView::setSource(QUrl const&) libPlasmaQuick.so.8 #2 plasmashell #3 plasmashell #4 libQt6Core.so.6 #5 Plasma::Corona::containmentUiReadyChanged(Plasma::Containment*, bool) libPlasma.so.8 #6 libQt6Core.so.6 #7 Plasma::Containment::uiReadyChanged(bool) libPlasma.so.8 #8 libPlasma.so.8 #9 QObject::event(QEvent*) libQt6Core.so.6 #10 QApplicationPrivate::notify_helper libQt6Widgets.so.6 #11 QCoreApplication::notifyInternal2 libQt6Core.so.6 #12 QTimerInfoList::activateTimers libQt6Core.so.6 then the glib/Qt event loop back to QCoreApplication::exec and plasmashell main. Signal 11, SEGV_MAPERR, fault address 8. Executable was /usr/bin/plasmashell --no-respawn from the 6.8.0 packages. I cannot produce file names and line numbers unless the 6.8.0 system is booted again with debug symbols, which brings the black screen back. -- You are receiving this mail because: You are watching all bug changes.
