因此，自從開發人員預覽版終於推出後，我開始在Linux上開始玩Java FX。我正在關注網站上的第一個示例（Getting Started with JavaFX），並且一切似乎都正常運行。但是，運行該示例時，我所得到的只是一個空白窗口。在Linux上運行Java FX 2.0應用程序時出現空白屏幕
我檢查過以確保我使用JDK7u3中包含的JRE for linux。
奇怪的是我在運行這個例子時沒有遇到任何異常或問題，我只是得到一個什麼都不做的空白窗口。我甚至可以爲舞臺設置一些屬性，例如設置標題或大小，並反映這些更改;但場景中沒有任何內容顯示，甚至沒有背景顏色。
有沒有人有任何想法，我可能做錯了什麼？
更新： 感謝您的回覆;這是代碼和截圖，謝爾蓋。我刪除了大部分的例子，並且只剩下階段創建：
public class UITest extends Application {
@Override
public void start(Stage mainStage) {
try {
Group root = new Group();
Scene scene = new Scene(root, 400, 300, Color.RED);
mainStage.setScene(scene);
mainStage.show();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
這說明THIS窗口。
我使用Ubuntu 11.10並在Eclipse上運行示例。
與-Dprism.verbose = true參數輸出是：

這是一個開發人員的預覽，所以不是所有的Linux版本和硬件都支持。什麼是您的操作系統版本？另外，你可以嘗試運行標誌爲'-Dprism.verbose = true'的應用程序並提供輸出嗎？ – 2012-03-19 13:21:20
和截圖？ – 2012-03-19 14:19:57
誰有這種情況？ – corbenik 2012-03-22 15:31:56
