Description

I have a mini-PC configured to suspend after 15 minutes. Besides the "unable to lock, use loginctl unlock-session N" issue described by Walter, when the mini-PC wakes up from suspend, the entire KDE Plasma session is gone, including all programs that were running in it, and abrt-applet prompts me to report a crash in each of the running program. Clicking a wallpaper in System Settings, as described by Walter, solves both the "use loginctl" and the "session dies on suspend" issues for me. qt6-qtwayland 6.9.1-2 seems to be involved here: https://bugzilla.redhat.com/show_bug.cgi?id=2375356 With that reverted to 6.9.1-1, and nothing else reverted (i.e. all Plasma-related packages at their latest version), I don't get this issue at all. If I reupgrade qt6-qtwayland to 6.9.1-2 again, and don't touch any other packages. the lockscreen issue comes back. I cannot confirm some here: 1. I had a wallpaper set, and yet was hit by this. 2. After logging in through ssh, and unlock the session, everything was up as of before, luckily. 3. My workaround is to simply set the screen lock to "Never". I *think* I could not reach a virtual console, like what was suggested on the black screen. I am not sure, because I was nervous since I had some process running for a few hours and was most keen to not lose it. The "broken screenlocker" screen suggests Ctrl-Alt-F1 for a virtual console, which on most Fedora installs I think won't work. Ctrl-Alt-F3 should work. Downgrading qt6-qtwayland to 6.9.1-1 should resolve the issue: a couple of methods are suggested in comments at https://bugzilla.redhat.com/show_bug.cgi?id=2375356 btw my own experience was that changing the wallpaper seemed to mitigate the issue for a short time, but until I downgraded qt6-qtwayland, the lockscreen issue kept coming back: I didn't figure out exactly what conditions retriggered it. A related bug https://bugzilla.redhat.com/show_bug.cgi?id=2375438 appears to have been raised against layer-shell-qt. I don't have access to it, but I guess Red Hat folks may. Running Fedora 42 with KDE plasma desktop on 2024 HP laptop with 32GB ram - no virtual session. None of the Function keys seem to allow exit from error screen and hard shutdown seems to be only option. Deprecating to earlier version qt6-qtwayland-6.9.1-2.fc42 that appears to work for now but await testing on a released fix. (In reply to Dawson from comment #6) > Deprecating to earlier version qt6-qtwayland-6.9.1-2.fc42 that appears to > work for now but await testing on a released fix. 6.9.1-3.fc42 (which reverts the problematic change in 6.9.1-2 and restores the ABI of 6.9.1-1) has now been released into stable Fedora 42. https://bugzilla.redhat.com/show_bug.cgi?id=2375356#c33 This message is a reminder that Fedora Linux 41 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a 'version' of '41'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, change the 'version' to a later Fedora Linux version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see it. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora Linux 41 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora Linux, you are encouraged to change the 'version' to a later version prior to this bug being closed. Fedora Linux 41 entered end-of-life (EOL) status on 2025-12-15. Fedora Linux 41 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora Linux please feel free to reopen this bug against that version. Note that the version field may be hidden. Click the "Show advanced fields" button if you do not see the version field. If you are unable to reopen this bug, please file a new report against an active release. Thank you for reporting this bug and we are sorry it could not be fixed. |
