Turn off the monitor and on again always disconnects the Plasma session on Wayland and you are back to the SDDM login screen. As soon as you turn on the monitor kwin will crash somehow. The issue exists only with my external GPU (AMD RX 480), the issue happens since a long time but in the past in most cases it froze the system (this driver bug is solved now). The same issue happens as well if power management is active and Plasma turns off the screen after some time and you wake up the system later on. See logs below based on kwin-git and kscreen-git from 2019-01-06. STEPS TO REPRODUCE 1. Turn off the monitor 2. Turn the monitor on again OBSERVED RESULT Kwin crashes all the time, Plasma session is disconnected and you are back to the SDDM login screen. You can open only a new session now. EXPECTED RESULT Screenlocker allows you to unlock the open Plasma session and you can continue to work with the previous open applications.

Marking us duplicate of similar report from a few days ago. As you have a git build I would be highly interested in some further debug information. E.g I would like to know the value of screenId in frame #3. *** This bug has been marked as a duplicate of bug 402827 ***
Thanks for your fast feedback! It might be a stupid question but where do I get the screenid from? Is this set by Qt? Or do I miss some debug symbols? $ qtdiag Using Wayland-EGL This plugin does not support createPlatformVulkanInstance QVulkanInstance: Failed to initialize Vulkan Qt 5.12.0 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 8.2.1 20181127) on "wayland" OS: Arch Linux [linux version 4.20.0-arch1-1-ARCH] Architecture: x86_64; features: SSE2 SSE3 SSSE3 SSE4.1 SSE4.2 AVX AVX2 Environment: QT_AUTO_SCREEN_SCALE_FACTOR="0" QT_WAYLAND_DISABLE_WINDOWDECORATION="1" QT_WAYLAND_FORCE_DPI="132" Features: QT_NO_EXCEPTIONS Library info: PrefixPath: /usr DocumentationPath: /usr/share/doc/qt HeadersPath: /usr/include/qt LibrariesPath: /usr/lib LibraryExecutablesPath: /usr/lib/qt/libexec BinariesPath: /usr/bin PluginsPath: /usr/lib/qt/plugins ImportsPath: /usr/lib/qt/imports Qml2ImportsPath: /usr/lib/qt/qml ArchDataPath: /usr/lib/qt DataPath: /usr/share/qt TranslationsPath: /usr/share/qt/translations ExamplesPath: /usr/share/doc/qt/examples TestsPath: /usr/tests SettingsPath: /etc/xdg Standard paths [*...* denote writable entry]: DesktopLocation: "Desktop" */home/rainer/Desktop* DocumentsLocation: "Documents" */home/rainer/Dokumente* FontsLocation: "Fonts" */home/rainer/.local/share/fonts* /home/rainer/.fonts ApplicationsLocation: "Applications" */home/rainer/.local/share/applications* /home/rainer/.local/share/flatpak/exports/share/applications /var/lib/flatpak/exports/share/applications /usr/local/share/applications /usr/share/applications MusicLocation: "Music" */home/rainer/Musik* MoviesLocation: "Movies" */home/rainer/Videos* PicturesLocation: "Pictures" */home/rainer/Bilder* TempLocation: "Temporary Directory" */tmp* HomeLocation: "Home" */home/rainer* AppLocalDataLocation: "Application Data" */home/rainer/.local/share/QtProject/qtdiag* /home/rainer/.local/share/flatpak/exports/share/QtProject/qtdiag /var/lib/flatpak/exports/share/QtProject/qtdiag /usr/local/share/QtProject/qtdiag /usr/share/QtProject/qtdiag CacheLocation: "Cache" */home/rainer/.cache/QtProject/qtdiag* GenericDataLocation: "Shared Data" */home/rainer/.local/share* /home/rainer/.local/share/flatpak/exports/share /var/lib/flatpak/exports/share /usr/local/share /usr/share RuntimeLocation: "Runtime" */run/user/1000* ConfigLocation: "Configuration" */home/rainer/.config* /etc/xdg DownloadLocation: "Download" */home/rainer/Downloads* GenericCacheLocation: "Shared Cache" */home/rainer/.cache* GenericConfigLocation: "Shared Configuration" */home/rainer/.config* /etc/xdg AppDataLocation: "Application Data" */home/rainer/.local/share/QtProject/qtdiag* /home/rainer/.local/share/flatpak/exports/share/QtProject/qtdiag /var/lib/flatpak/exports/share/QtProject/qtdiag /usr/local/share/QtProject/qtdiag /usr/share/QtProject/qtdiag AppConfigLocation: "Application Configuration" */home/rainer/.config/QtProject/qtdiag* /etc/xdg/QtProject/qtdiag File selectors (increasing order of precedence): de_DE unix linux arch Network: Using "OpenSSL 1.1.1a 20 Nov 2018", version: 0x1010101f Platform capabilities: ThreadedPixmaps OpenGL ThreadedOpenGL BufferQueueingOpenGL MultipleWindows NonFullScreenWindows NativeWidgets WindowManagement RasterGLSurface Style hints: mouseDoubleClickInterval: 400 mousePressAndHoldInterval: 800 startDragDistance: 10 startDragTime: 500 startDragVelocity: 0 keyboardInputInterval: 400 keyboardAutoRepeatRate: 30 cursorFlashTime: 1000 showIsFullScreen: 0 showIsMaximized: 0 passwordMaskDelay: 0 passwordMaskCharacter: U+25CF fontSmoothingGamma: 1 useRtlExtensions: 0 setFocusOnTouchRelease: 0 tabFocusBehavior: Qt::TabFocusAllControls singleClickActivation: 1 Additional style hints (QPlatformIntegration): ReplayMousePressOutsidePopup: 1 Theme: Platforms requested : kde available : kde,gtk3,snap,flatpak,xdgdesktopportal Styles requested : breeze,oxygen,fusion,windows available : Breeze,Oxygen,Windows,Fusion Icon theme : breeze, hicolor from /home/rainer/.local/share/icons,/var/lib/flatpak/exports/share/icons,/usr/share/icons System font : "Noto Sans" 10 Fonts: General font : "Noto Sans" 10 Fixed font : "Hack" 9 Title font : "Noto Sans" 10 Smallest font: "Noto Sans" 8 Palette: QPalette::WindowText: #ff232627 QPalette::Button: #ffeff0f1 QPalette::Light: #ffffffff QPalette::Midlight: #fff7f7f8 QPalette::Dark: #ff888e93 QPalette::Mid: #ffc4c9cd QPalette::Text: #ff232627 QPalette::BrightText: #ffffffff QPalette::ButtonText: #ff232627 QPalette::Base: #fffcfcfc QPalette::Window: #ffeff0f1 QPalette::Shadow: #ff474a4c QPalette::Highlight: #ff3daee9 QPalette::HighlightedText: #fffcfcfc QPalette::Link: #ff2980b9 QPalette::LinkVisited: #ff7f8c8d QPalette::AlternateBase: #ffeff0f1 QPalette::NoRole: #ff000000 QPalette::ToolTipBase: #ff232627 QPalette::ToolTipText: #fffcfcfc QPalette::PlaceholderText: #80232627 Screens: 1, High DPI scaling: inactive #
