--- Comment #12 from agzgtrtvquysegf...@nthrw.com --- I indeed have polkit installed. If I just restart plasmashell I do not get any useful errors, but if I remove taskmanager and readd it to the panel I get the same message as you (together with some semi related things next to it): file:///usr/lib/qt/qml/org/kde/plasma/extras/PlasmoidHeading.qml:75: TypeError: Value is undefined and could not be converted to an object org.kde.kf5.kwindowsystem.kwayland: This compositor does not support the Plasma Window Management interface This plugin does not support setting window opacity Arrived mimeData () ("text/x-plasmoidservicename") at 12 , 811 adding "org.kde.plasma.taskmanager" This plugin does not support setting window opacity So at least I think it's not polkit. -- You are receiving this mail because: You are watching all bug changes.
