Bug ID: 524789
Summary: Plasma Login Manager black screen after
plasma-workspace 6.7.4-2 update: QML fails with Qt
undefined symbol
Classification: Plasma
Product: plasmashell
Version First 6.7.4
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
After updating Plasma packages on Fedora 44 from 6.7.4-1.fc44 to 6.7.4-2.fc44,
Plasma Login Manager only showed a black screen.
The login manager itself started, including its Wayland/KWin session, but the
greeter QML failed to load because Plasma libraries referenced a Qt symbol that
could not be resolved:
_ZN23QUntypedPropertyBindingC1EP23QPropertyBindingPrivate, version Qt_6
Downgrading the Plasma packages back to 6.7.4-1.fc44 with dnf history undo
restored the login screen.
