Created attachment 172523 [details] Logs generated from the startup script. SUMMARY Plasma with Wayland fails to start on FreeBSD. X11 session starts fine though. I am using a i5-8265U processor with integrated graphics and have drm-515-kmod installed. Attached are the logs generated from the startup script posted below. STEPS TO REPRODUCE This is the startup script I used: #!/usr/local/bin/zsh export TZ=Europe/Belgrade export WAYLAND_DEBUG=1 export QT_DEBUG_PLUGINS=1 export QT_LOGGING_RULES="kwin_*=true;qt.*=true" export XDG_SESSION_TYPE="wayland" export QT_QPA_PLATFORMTHEME=qt6ct export QT_QPA_PLATFORM=wayland export LIBSEAT_BACKEND=consolekit2 export QT_WAYLAND_SHELL_INTEGRATION="xdg-shell" exec -- ck-launch-session dbus-launch --exit-with-session startplasma-wayland |& tee ~/start-plasma.sh.log OBSERVED RESULT Plasma on Wayland doesn't start. See the log files. EXPECTED RESULT Plasma on Wayland should start. SOFTWARE/OS VERSIONS Operating System: FreeBSD 14.1 KDE Plasma Version: 6.1.2 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 Kernel Version: 14.1-RELEASE-p3 (64-bit) Graphics Platform: Wayland Memory: 15.8 GiB of RAM Graphics Processor: Mesa Intel UHD Graphics 620
