title: Blank screen when running a Java FX 2.0 application on linux
body: <p>So, I just started toying with Java FX on Linux since the developer preview finally came out. I'm following the first example on the site (<a href="http://docs.oracle.com/javafx/2.0/get_started/jfxpub-get_started.htm" rel="nofollow">Getting Started with JavaFX</a>) and everything seems to be running OK. However, all I get is a blank window when running the example.</p>
  
  <p>I've checked to make sure I'm using the JRE included on the JDK7u3 for linux.</p>
  
  <p>The weird thing is I don't get any exceptions or problems when running the example, I just get the blank window which does nothing. I can even set some properties for the Stage, like setting the title or the size, and those changes are reflected; but nothing on the Scene shows, not even the background color.</p>
  
  <p>Does anyone have any ideas as to what I may be doing wrong?</p>
  
  <p>UPDATE:
  Thanks for your reply; here's the code and the screenshot, Sergey. I removed most of the example and left only the stage creation:</p>
  
  <pre><code>    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);
      }
  }
  </code></pre>

  <p>I'm using Ubuntu 11.10 and running the example on Eclipse.</p>
