JOGL on Linux - Freezes

Hi,
I've been playing around with JOGL for a couple of weeks now, and have had no problems with Windows. I recently installed Ubuntu 11.04, and the exact same code that has worked fine on Windows, hangs up on Linux unless the window receives a mouse or keyboard event. I'm using NativeWindow, ATI accelerated drivers for a 4890. Can post code if required - it's based on the RedSquare demo with minor changes only, and looks fine - no graphical glitches or anything.

The stack looks like this when a freeze happens:

EITHER:
Thread [main] (Suspended)
        GLX.dispatch_glXSwapBuffers1(long, long, long) line: not available [native method]
        GLX.glXSwapBuffers(long, long) line: 1124
        X11OnscreenGLXDrawable(X11GLXDrawable).swapBuffersImpl() line: 68
        X11OnscreenGLXDrawable(GLDrawableImpl).swapBuffers() line: 94
        GLDrawableHelper.invokeGL(GLDrawable, GLContext, Runnable, Runnable) line: 366
        GLWindow.display(boolean) line: 547
        GLWindow.display() line: 523
        JoglTestShader.main(String[]) line: 32

OR:
Thread [main] (Suspended)
        GLX.dispatch_glXMakeContextCurrent1(long, long, long, long, long) line: not available [native method]
        GLX.glXMakeContextCurrent(long, long, long, long) line: 936
        X11OnscreenGLXContext(X11GLXContext).glXMakeContextCurrent(long, long, long, long) line: 152
        X11OnscreenGLXContext(X11GLXContext).makeCurrentImpl(boolean) line: 412
        X11OnscreenGLXContext(GLContextImpl).makeCurrentLocking() line: 419
        X11OnscreenGLXContext(GLContextImpl).makeCurrent() line: 352
        GLDrawableHelper.invokeGL(GLDrawable, GLContext, Runnable, Runnable) line: 348
        GLWindow.display(boolean) line: 547
        GLWindow.display() line: 523
        JoglTestShader.main(String[]) line: 32

Is this an error on my part, or in JOGL/Ubuntu?

Hi!

I frequently test JOGL on several Linux distros (KUbuntu, Mandriva, Mageia, Cent OS, Debian, etc...) and I have never experienced such problems. However, there might be some problems with some particular drivers but they concern all OpenGL applications, not only those using JOGL. For example, the Nouveau driver on NVIDIA graphics card gives me a black screen with JOGL 1.1.1a on Mageia Linux 1 whereas the proprietary driver works fine.

ATI Radeon HD drivers work bad sometimes, try to use an ATI Radeon driver instead. Which driver do you use?

Some French Linux Debian users had to use Vesa drivers which work reliably but are quite slow in order to work around this problem :( I remind you that it is not a problem specific to JOGL.

Do you call initSingleton ?

Is thig bug reproducible with GLCanvas?

no, because AWT utilization is not multi threaded :)
