Odd error on linux with NewtCanvasAWT

Hi,

I have the following code that works correctly the first time it is called:

        private GLWindow canvas;

        private NewtCanvasAWT newtCanvas;
       
        private JFrame frame;

        public void show() {
        GLCapabilities caps = new GLCapabilities(GLProfile.get(GLProfile.GL2));
        canvas = GLWindow.create(caps);

        newtCanvas = new NewtCanvasAWT(canvas);
        frame = new JFrame("A Name");
        frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        frame.setSize(960,640);
        frame.add(newtCanvas);
        frame.setVisible(true);

        canvas.addGLEventListener(this);
        animator = new Animator(canvas);
        animator.add(canvas);
        animator.start();
        ...
}

But the second time it is called, I get this error (the exception is thrown on the frame.setVisible() line):

Where am I going wrong? I am using Ubuntu 12.04 and a pretty recent build of JOGL.

Hi

It reminds me this case:
http://jogamp.org/wiki/index.php/Tegra2_TrimSlice_running_Ubuntu_natty_using_the_L4T_alpha_driver

Maybe it is a driver bug but we should check that. Please can you provide me a small test case or find an existing one that exhibits this behavior? I will be able to use it on 2 machines with GNU Linux and Nvidia graphics cards.

can you pls provide a complete test case ?
Also pls provide more information as described in our Wiki (-> FAQ/Bugreport),
you can also search the forum for 'bugreport' if you feel unsure.

Thank you ..

I will provide a full test case - but probably won't have a chance to do so before the weekend. I hope it is possible to reuse an instance of a newtcanvas as the code works OK the first time... I will try that as well.

Thank you.

Since we already have lots of test cases in our repository,
it would be best to browse through them for a while and
maybe use a similar one for your purpose, copy it to a new named class and
patch it. This may even give us insight why we don't handle your use case.
