SUMMARY I noticed that the same error message of xdg-desktop-portal-kde appears in the journalctl log every reboot or re-login. The error message: ----------------- xdg-desktop-portal-kde: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb. systemd-coredump: [🡕] Process 1344 (xdg-desktop-por) of user 963 dumped core. ----------------- I guess that the issue was caused by update some QT package that would break xdg-desktop-portal-kde. See the error message in the log: https://github.com/flatpak/xdg-desktop-portal/issues/896#issuecomment-1265385153 See the same issue: https://bbs.archlinux.org/viewtopic.php?id=279527 STEPS TO REPRODUCE 1. Just install any Arch based distro or Manjaro Testing branch in VM 2. Update system 3. Install xdg-desktop-portal-kde 4. Reboot and see the error log in "journalctl -b 0 -p err" SOFTWARE/OS VERSIONS - Manjaro Testing branch: - KDE Plasma Version: 5.25.5 - KDE Frameworks Version: 5.98.0 - Qt Version: 5.15.6 - Graphics Platform: Wayland - xdg-desktop-portal 1.15.0-1 - xdg-desktop-portal-kde 5.25.5-1
