Hello, All
I’m trying to bring Plasma Big Screen to Amlogic S905X4.
I’m using Yocto kirkstone released here: Packaging / Yocto Manifests · GitLab
The SOC do not support X11, only support OpengGLES, after some hacking, the image can build and start successfully
There is no any KDE log in systemd log
so I modify /usr/bin/plasma-bigscreen-wayland as below
startplasma-wayland --libinput --exit-with-session=/usr/libexec/startplasma-waylandsession > /tmp/pp.log 2>&1
then I can get below log:
org.kde.plasma.session: Tao Here123

The screen is keep black, no splash . but kwin is running, I can run ksplashqml by manual, and it shows on screen

QObject: Cannot create children for a parent that is in a different thread.
(Parent is SplashApp(0x7fe23d4ac8), parent's thread is QThread(0x55b9d916b0), current thread is QThread(0x55b9dab800)
QObject::installEventFilter(): Cannot filter events for objects in a different thread.
I can also run others GUI apps such as kdeconnect-app, kfontview, kclock
My questions are below:
- what’s the correct way get full kde logs.
- what’s the root cause plasma can not start but kwin is working. How can I debug more
- It seems QT6 support wayland better, but I’m not sure whether kirkstone-qt6.xml is ready @Andreas_Cord-Landweh
