Hello everyone KScreenLocker shows black screen after some minutes of sleep (laptop). It's not showing nothing (any icon, cursor, nothing), even if I login from tty2 (CTRL + ALT + F2). It's not happens everytime, only in random times. I've searched around my journalctl and found this errors: jun 21 13:21:46 pinguim kscreenlocker_greet[13691]: Qt: Session management error: networkIdsList argument is NULL jun 21 13:21:47 pinguim kscreenlocker_greet[13691]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/> jun 21 13:21:47 pinguim kscreenlocker_greet[13691]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/> jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/> jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/> jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/> jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim plasmashell[9763]: QXcbClipboard::setMimeData: Cannot set X11 selection owner jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim plasmashell[9763]: QXcbClipboard::setMimeData: Cannot set X11 selection owner jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old jun 21 13:21:48 pinguim kscreenlocker_greet[13691]: QXcbClipboard: SelectionRequest too old I tried to run '/usr/lib/kscreenlocker_greet --testing', but it's everything fine (As I've said, the black screen thing happens randomly) with some minors errors: file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/components/VirtualKeyboard.qml:8:1: module "QtQuick.VirtualKeyboard" is not installed file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml:222: ReferenceError: wallpaper is not defined Locked at 1655831997 file:///usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/components/UserList.qml:43:9: Unable to assign [undefined] to bool SOFTWARE/OS VERSIONS Linux: Arch Linux x86_64 - Kernel 5.18.5-arch1-1 KDE Plasma Version: Plasma 5.25.1 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION It's happens in both X11 and Wayland sessions

Hmm, not the same thing as here there's no cursor.
Hi Higor, sorry it took so long to get to this. If it is still happening in Plasma 5.27, can you comment on what kind of GPU you have on the machine? Thanks!
Actually I have even more questions: - Does it happen when the system locks the screen? - Does it happen when the system puts the display to sleep? - Does it happen when the system suspends? - Are there more than one screen? - Are there more than one GPU? - Is it a PRIME system with muxing? If so, which GPU was driving the display? - Is the cursor visible? - Are there any GUI elements visible? - Is the broken lock screen function (e.g. blindly typing your password and hitting Enter unlocks)? - Is there a method that brings you back to a working desktop (e.g. killing kscreenlocker_greet). - Is the desktop session using X11 or Wayland?
