The following repeats until java is exited: exception in QueueFlusher: javax.media.opengl.GLException: context creation error: couldn't find a suitable frame buffer configuration at com.sun.opengl.impl.x11.X11ExternalGLDrawable$Context.create(X11ExternalGLDrawable.java:180) at com.sun.opengl.impl.x11.X11ExternalGLDrawable$Context.makeCurrentImpl(X11ExternalGLDrawable.java:123) at com.sun.opengl.impl.GLContextImpl.makeCurrent(GLContextImpl.java:134) at com.sun.opengl.impl.GLDrawableHelper.invokeGL(GLDrawableHelper.java:182) at javax.media.opengl.GLJPanel$2.run(GLJPanel.java:650) at sun.java2d.opengl.OGLRenderQueue$QueueFlusher.run(OGLRenderQueue.java:203) Platform is kubuntu linux 7.04, with GL_VENDOR: ATI Technologies Inc. GL_RENDERER: MOBILITY RADEON 9600 GL_VERSION: 2.0.6334 (8.34.8) java version "1.6.0_02" Java(TM) SE Runtime Environment (build 1.6.0_02-b05) Java HotSpot(TM) Client VM (build 1.6.0_02-b05, mixed mode, sharing) jogl version nightly build 20070823. ---- Additional Comments From kbr 2007-08-24 08:53:25 ---- It's unlikely there is anything we can do about this problem in JOGL. It seems that most vendors' OpenGL drivers have gotten much less stable with regard to Frame Buffer Object implementation recently, and the Java 2D / OpenGL pipeline barely works right now, let alone the Java 2D / JOGL bridge. The same code used to work with older driver versions from various vendors including NVidia and ATI. I would suggest you send a bug report to ATI. Nothing has changed in the JOGL or Java SE code bases which would have introduced this instability, only the vendors' graphics drivers. ---- Additional Comments From kbr 2008-03-30 16:46:13 ---- There hasn't been any action on this bug in a long while. Since I think this is most likely an OpenGL driver problem I'm closing it as "invalid". Note that there are some rewrites coming to the GLJPanel which should hopefully make it work more reliably in conjunction with the Java 2D / OpenGL pipeline, and changes to the Java 2D OpenGL pipeline itself to make it more reliable across a wider range of graphics drivers. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:50 EDT --- This bug was previously known as _bug_ 314 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=314
