Upgraded from KDE Neon 22.04 to 24.04 backend and it's broken unlocking the session if left over night. Shorter periods even of several hours it works fine. Over night I need to go to another virtual terminal; and use loginctl unlock-session Operating System: KDE neon 6.2 KDE Plasma Version: 6.2.3 KDE Frameworks Version: 6.7.0 Qt Version: 6.8.0 Kernel Version: 6.8.0-48-generic (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: AMD Radeon RX 580 Series Package: kscreenlocker Version: 6.2.3-0zneon+24.04+noble+release+build10 See the following messages: Nov 09 11:36:02 monolith kscreenlocker_greet[722401]: file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen/LockScreenUi.qml:128: TypeError: Property 'startAuthenticating' of object TypeError: Type error is not a function Nov 09 11:36:09 monolith kscreenlocker_greet[722401]: file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen/LockScreenUi.qml:280: TypeError: Property 'respond' of object length is not a function
Setting an environment value in /etc/profile.d/kde_bug_fix.sh #!/bin/bash QV4_GC_TIMELIMIT=0 export QV4_GC_TIMELIMIT Solved the issue for me.
