I am running Fedora 19. When I plugin my computer into my dock with an external monitor and click on the Logout/Restart buttons they are visible on the external (primary) monitor. After unplugging from the dock (so the laptop is primary again) then the buttons do not appear - the screen still dims and if I hit enter I get the default action - its as if they have appeared offscreen. Reproducible: Always
Dear Bug Submitter, This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone!
I am closing this as I can no longer reproduce it.
( Note : tested with Fedora 28 )
