SUMMARY The screen locker is broken and unlocking is not possible anymore. In order to unlock switch to a virtual terminal(Ctrl+Alt+F2), login and execute the command loginctl unlock-session 2. Afterwards switch back to the running session (Ctrl+Alt+F1) STEPS TO REPRODUCE 1. Lock screen 2. Turn off TV/Monitor 3. Turn on TV/Monitor OBSERVED RESULT error message displayed and loginctl unlock_sessions does not work EXPECTED RESULT To type my password and have the session unlock SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: 5.22.0 (available in About System) KDE Plasma Version: 5.22.0 KDE Frameworks Version: latest Qt Version: latest ADDITIONAL INFORMATION

There isn't a lot to go on from these comments. Journalctl output after the event? I suspect this is the same cause as 438839.

Ok, not quite the same as 438839 but similar. We're getting the placeholder screen. That gets into ``` init(shell->get_layer_surface(window->waylandSurface()->object(), window->waylandScreen()->output(), interface->layer(), interface->scope())); ``` This then obviously crashes.
What priority is it to fix this issue? How soon will it be fixed? Sorry about my impatience.
Don't do that please. If you want to help please confirm the blind theory above with some debug on your system that reproduces it.
I have the same problem, but what I can add to this bug report is it happens when my Monitor is using the Deep Sleep function, which is like a standby function. In this mode the OS needs do a power cycle on video adapter to wake the monitor up. I have tried just turn off the option but was in vain, because I reinstalled the system(moved to f2fs on a NVME SSD) few day ago and forgot to add the kernel instruction on the bootloader for optimize power on my AMD RDNA2 (amdgpu.aspm=1). This is the 3rd day I test it and the problem can be avoided doing this. Neither Kernel 5.11.x to 5.13.x can wake up the monitor in this state, which covers all new AMD Cards (Big Navi / RX 6000 / Navi 2x / RDNA2)), at least not using open source drivers. On Windows it work. An issue still related is soon after I unlock the session I can notice all my KDE Apps reside to another shape, Konsole, Dolphin, Konversation are examples. My theory is when the machine enters in a state of "standby"(not hibernating or suspended) the video adapter sleep, and Wayland can't find any available display to handle the session to unlock the screen, also resizing to small resolution. Maybe what we need in here is to a dummy video adapter to exist and handle stuff while none are available, changing back to the first available adapter after. Just for observation, using X.Org this issue of unlocking session doesn't happen, the other however still exist. https://www.phoronix.com/scan.php?page=news_item&px=AMDGPU-Linux-5.12-More-Fixes Operating System: Slackware 15.0-beta KDE Plasma Version: 5.22.3 KDE Frameworks Version: 5.84.0 Qt Version: 5.15.2 Kernel Version: 5.12.16 (64-bit) Graphics Platform: Wayland Processors: 28 × Intel® Xeon® CPU E5-2697 v3 @ 2.60GHz Memory: 125.7 GiB of RAM Graphics Processor: AMD Radeon RX 6800 XT

How do I get debug info from kscreenlocker?

2021-06-24 I reported the bug. I don't know the date this bug was confirmed. It is now 2021-07-30. How patient need I be? Should I have a six pack beer every day to help me get to the day it is fixed? I asked how to get the debug report for kscreenlocker on 2021-07-21, but I did not get an answer. I guess it is not needed from me. Please give me a rough estimate for when it will be fixed?
I do not need any further info. I do need you to not spam my bug tracker. It makes it hard to find the comments that do add value. To post an update: There was a patch for layershell-qt that got merged. That might fix the issue on it's own, but ideally we need to refactor kscreenlocker code to handle screens in a more sane way then add a guard for the null geometry that we would get from Qt's placeholder screen.

Just to answer this question to Cane Kostovski from comment #24 If you intend the determine version of the package and to figure out if it contains the patch, you've searched wrong, use regex for those cases: ``` zypper search layer | grep -iE "(shell|qt)" ``` > i+ | layer-shell-qt5 | wlr-layer-shell integration for Qt 5 Here's the changelog by the way: https://opensuse.pkgs.org/tumbleweed/kde-frameworks-5-x86_64/layer-shell-qt5-5.22.4-8.2.x86_64.rpm.html

Avoid creating windows for placeholder screens. Unfortuantely QPlatformScreen::isPlaceholder is not exposed so we need a heuristic. On wayland all placeholder screens have a null geometry. We also know that any real screen must have a geometry so we don't need to watch that QScreen for changes.

i installed layer-shell-qt5-5.22.4-8.2.x86_64.rpm from https://opensuse.pkgs.org/tumbleweed/kde-frameworks-5-x86_64/layer-shell-qt5-5.22.4-8.2.x86_64.rpm.html with only one screen i still have this issue.
Are you using kscreenlocker from git master? Because that's where the KDE part of the fix is.
i only took layer-shell-qt5, if i also need kscreenlocker, i will wait, thanks
I wonder if they don't verify it for version 5.23 My electric bill will be huge?
If anyone does have issues with Plasma 5.23 please open a new bug with a new backtrace.
Git commit 4a439143baf75b9a00cf17a3b7a34ae9ac93c68a by David Edmundson. Committed on 15/09/2021 at 22:55. Pushed by davidedmundson into branch 'master'. Fix a crash when creating views on the placeholder screen When a compositor has no outputs listed Qt creates a dummy placeholder QScreen object that does not represent a wl_output. This should still be fixed in the clients to not create a view, it's wasteful and probably will still have plenty of other bugs, hence the giant warning, but it's still worth guarding.
