X11 이 아닌 Weston(Wayland reference compositor) 에서 Avalonia 로 빌드한 프로그램이 실행가능함을 확인하였다.
실행환경 : i.MX8 시리즈 CPU, Debian 11, Weston

Add a NativeEmbeddingControl class that inherits from NativeControlHost in MainWindow.axaml.cs
namespace AvaloniaDXPlayer
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
...
public class NativeEmbeddingControl : NativeControlHost
{
public IntPtr Handle { get; private set; }
protected override IPlatformHandle CreateNativeControlCore(IPlatformHandle parent)
{
var handle = base.CreateNativeControlCore(parent);
Handle = handle.Handle;
Console.WriteLine($"Handle : {Handle}");
return handle;
}
}
}
