http://bugzilla.opensuse.org/show_bug.cgi?id=1166496 Bug ID: 1166496 Summary: KDE: Screen saver fails to lock screen while display is switched to a different virtual terminal Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: All OS: Linux Status: NEW Severity: Critical Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: jw@raven.inka.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- On several freshly installed systems with KDE, the screen saver won't lock the screen while a different virtual terminal is active. I can see the Problem with opensuse-Leap-15.1 as well as with ubuntu-18.04 (when kubuntu-desktop is installed) How to reproduce: 1. Configure the screen saver to 1 minute and require the password after additional 5 seconds. 2. While the screen saver in not active, activate a different virtual terminal (e.g. by pressing CTL-ALT-F2) 3. Wait for more than 70 seconds. 4. Switch back to the desktop Expected behavior: Screen saver is active and only the password screen is visible. Actual behavior: when switching back, all the open applications (possibly showing confidential data!) are visible for about one second. Only then the screen starts to dim. And due to the setting of 5 seconds for password requirement, one can stop the screen saver just by typing some key or moving the mouse. Result of mailing list discussion so far: - Problem can be reproduced by other people - Problem does appear with sddm, lightdm and kdm - Problem does not seem to appear with gdm and xfce Mailing list thread: https://lists.opensuse.org/opensuse/2020-03/msg00267.html -- You are receiving this mail because: You are on the CC list for the bug.
