Kcreenlocker will lock the screen. When I login it goes to a black screen and returns to the lock screen to login again. I noticed that my hard drive was nearly full. I checked and I had lots of core dumps from kscreenlocker. I have disabled kscreenlocker for now. Reproducible: Always Steps to Reproduce: 1.lock screen through time out or menu 2.login using password 3. Actual Results: pushes to a black screen and asks to login again Expected Results: logged into the system
Probably also happened to me. Got 74GiB of core dump files. Unfortunately they seam to be broken. Cannot unpack them.
could you please provide some more information about the coredumps? I'm especially confused about the name "KScreenlocker" as there is no such binary called like that in the version you selected. There is a kscreenlocker_greet, though.

Reproduced on Archlinux with KDE Plasma Workspace 5.3.0 (package plasma-workspace 5.3.0-3). The crash happens every time the correct password is given in the lock screen window - if the wrong password is given, the process doesn't die. (We see in the log that Vim dies as well, but that seams to be completely different issue.)
PS! I can not log back in once the screen is locked:-) The only solution is the restart SDDM.
SOLVED (for me at least) Both Vim and kscreenlocker_g where crashing due to outdated Intel microcode. Following the guide bellow solved my problem: https://wiki.archlinux.org/index.php/Microcode
Thanks for giving an update on what solved the issue. Given that it's microcode I don't see anything we could do about it, thus the bug seems invalid to me. For future references: there was no need to restart the complete session. One can unlock using loginctl: 1. switch to tty and log in 2. loginctl unlock-sessions
