--- Comment #3 from Martin Gräßlin <mgraess...@kde.org> --- I think there is a bigger problem than the freezing of the locker. As the process is no longer running the screen should not show the window any more. It must be removed if the process dies. And that's the job of the X server. If kscreenlocker_greet crashes ksmserver will restart it. So that there is always a locker. If the restart fails for four times the lock screen architecture goes into emergency mode. The lock screen is replaced by a black screen with a message on how to unlock the screen with loginctl. Given that we should either have the process of the warning message. As both is not the case I fear the problem is deeper in the stack. If it happens the next time please try to get some more information about the system state. Check dmesg for error message (e.g. reported coredumps, hung gpu, etc). Check /var/log/Xorg.0.log for errors. Check top for whether a process is running amok. In case you are using logind you can also try to unlock the session with: loginctl unlock-sessions -- You are receiving this mail because: You are watching all bug changes.
