I actually thought it was a problem with my driver but using a GLCanvas everything works fine. I tried with jdk1.5.0,1.5.0_01, 1.4.2_05. GLCapabilities capabilities = new GLCapabilities(); JPanel panel = GLDrawableFactory.getFactory().createGLJPanel(capabilities); JFrame frame = new JFrame("OpenGL Test"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(400,400); frame.add(panel); frame.setVisible(true); ----------------------------------------------------------------------- Exception in thread "main" net.java.games.jogl.GLException: Unable to set pixel format at net.java.games.jogl.impl.windows.WindowsGLContext.choosePixelFormatAndCr eateContext(WindowsGLContext.java:493) at net.java.games.jogl.impl.windows.WindowsOffscreenGLContext.create(Window sOffscreenGLContext.java:181) at net.java.games.jogl.impl.windows.WindowsGLContext.makeCurrent(WindowsGLC ontext.java:135) at net.java.games.jogl.impl.windows.WindowsOffscreenGLContext.makeCurrent(W indowsOffscreenGLContext.java:12Cool at net.java.games.jogl.impl.GLContext.invokeGL(GLContext.java:250) at net.java.games.jogl.GLJPanel.reshape(GLJPanel.java:131) at java.awt.Component.setBounds(Component.java:1847) at java.awt.BorderLayout.layoutContainer(BorderLayout.java:809) at java.awt.Container.layout(Container.java:1401) at java.awt.Container.doLayout(Container.java:1390) at java.awt.Container.validateTree(Container.java:1473) at java.awt.Container.validateTree(Container.java:1480) at java.awt.Container.validateTree(Container.java:1480) at java.awt.Container.validateTree(Container.java:1480) at java.awt.Container.validate(Container.java:144Cool at java.awt.Window.show(Window.java:507) at java.awt.Component.show(Component.java:1300) at java.awt.Component.setVisible(Component.java:1253) ---- Additional Comments From kbr 2005-01-18 16:08:30 ---- A workaround appears to be to call setDoubleBuffered(false) on the GLCapabilities object passed to GLDrawableFactory.createGLJPanel(). This should be done automatically by the JOGL library if necessary. ---- Additional Comments From kbr 2005-01-31 01:39:05 ---- We've added a workaround which disables the double-buffering flag in the GLCapabilities for offscreen surfaces in the fix for Issue 41, so I'm marking this as a duplicate of that bug. The fix will be present in JOGL 1.1 b08. Please reopen this bug or open a new bug if problems persist. *** This issue has been marked as a duplicate of 41 *** --- Bug imported by sgothel@jausoft.com 2010-03-24 07:47 EDT --- This bug was previously known as _bug_ 129 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=129
