Problem with getting display mode

Question

Before I reinstall my Windows XP, the program works fine
but after I reinstall it, the program give me the error :
java.lang.InternalError: Could not get display modes
in this piece of code:
graphicEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
device = graphicEnv.getDefaultScreenDevice();
<b>DisplayMode dm = device.getDisplayMode();</b>
I think the false display settings are the reason. Could anybody help me?

You try to execute this first
GraphicsEnvironment ge = GraphicsEnvironment.
   getLocalGraphicsEnvironment();
   GraphicsDevice[] gs = ge.getScreenDevices();
   for (int j = 0; j < gs.length; j++) {
      GraphicsDevice gd = gs[j];
      GraphicsConfiguration[] gc =
     gd.getConfigurations();
      for (int i=0; i < gc.length; i++) {
         JFrame f = new
         JFrame(gs[j].getDefaultConfiguration());
         Canvas c = new Canvas(gc);
Rectangle gcBounds = gc[i].getBounds();
int xoffs = gcBounds.x;
int yoffs = gcBounds.y;
     f.getContentPane().add(c);
     f.setLocation((i*50)+xoffs, (i*60)+yoffs);
f.show();
