This is CentOS 5.5 64-bit, running as a guest OS inside VMWare server 2.0, running on Windows 7 64-bit. The graphics driver version from glxinfo is "OpenGL version string: 1.2 (1.5 Mesa 6.5.1)". I tried updating Mesa, but there are some dependency problems and I didn't want to break my OS installation. The problem seems to be that X11GLXGraphicsConfiguration.glXFBConfigID2FBConfig() is returning null. When I patch it to just return the first FB config, the program runs fine. I'm investigating. java.lang.Throwable: main - Info: NativeWindowFactory.<init> at javax.media.nativewindow.NativeWindowFactory.<clinit>(NativeWindowFactory.java:119) at javax.media.opengl.GLProfile.initProfilesForDefaultDevices(GLProfile.java:1164) at javax.media.opengl.GLProfile.access$000(GLProfile.java:71) at javax.media.opengl.GLProfile$1.run(GLProfile.java:117) at java.security.AccessController.doPrivileged(Native Method) at javax.media.opengl.GLProfile.initSingleton(GLProfile.java:115) at name.wadewalker.jogl2tests.onetriangle.OneTriangleSWT.<clinit>(OneTriangleSWT.java:29) main - NativeWindowFactory.initSingleton(false) Info: XInitThreads() called for concurrent Thread support X11Util.isFirstX11ActionOnProcess: false NativeWindowFactory.registerFactory() interface javax.media.nativewindow.NativeWindow -> jogamp.nativewindow.NativeWindowFactoryImpl@79f6f296 NativeWindowFactory firstUIActionOnProcess false NativeWindowFactory isAWTAvailable false, defaultFactory jogamp.nativewindow.NativeWindowFactoryImpl@79f6f296 GraphicsConfigurationFactory.registerFactory() class javax.media.nativewindow.x11.X11GraphicsDevice -> jogamp.nativewindow.x11.X11GraphicsConfigurationFactory@13c695a6 GraphicsConfigurationFactory.registerFactory() interface javax.media.nativewindow.AbstractGraphicsDevice -> jogamp.nativewindow.DefaultGraphicsConfigurationFactoryImpl@787bb290 GraphicsConfigurationFactory.registerFactory() class javax.media.nativewindow.x11.X11GraphicsDevice -> jogamp.opengl.x11.glx.X11GLXGraphicsConfigurationFactory@27bc82e7 X11 Display(NULL) <:0.0> GraphicsConfigurationFactory.registerFactory() class javax.media.nativewindow.egl.EGLGraphicsDevice -> jogamp.opengl.egl.EGLGraphicsConfigurationFactory@462ba11b java.lang.Exception: X11Util.Display: Created new NamedX11Display[:0.0, 0x45226340, refCount 1, unCloseable false].

In this case, we can't get the framebuffer config ID of the external context. Working by analogy with the solution in WindowsExternalWGLContext.create(), I made this change in X11ExternalGLXContext.create(): X11GLXGraphicsConfiguration cfg = null; if(1 != GLX.glXQueryContext(display, ctx, GLX.GLX_FBCONFIG_ID, val, 0)) { // sometimes external contexts don't give us a framebuffer config ID; if not, // create and use a default config GLCapabilities glcapsDefault = new GLCapabilities(GLProfile.getDefault()); cfg = X11GLXGraphicsConfigurationFactory.chooseGraphicsConfigurationStatic(glcapsDefault, glcapsDefault, null, x11Screen); if(DEBUG) { System.err.println("X11ExternalGLXContext invalid FBCONFIG_ID "+val[0]+", using default cfg: " + cfg); } } else { cfg = X11GLXGraphicsConfiguration.create(glp, x11Screen, val[0]); } This makes the SWT OneTriangle test pass. I'll try it on an SWT RCP app next. 947 3 wwalker3 2011-04-10 21:46:25 +0200 Confirmed that this works correctly for Eclipse RCP apps. Will try tomorrow on native (non-VMWare) CentOS to make sure this doesn't break the common case. 958 4 wwalker3 2011-04-13 02:35:54 +0200 Submitted a fix for this at https://github.com/sgothel/jogl/pull/35 (my branch https://github.com/WadeWalker/jogl/tree/2011-04-12-fix-bug-493). I've tested on native CentOS 5.5 with nvidia Quadro, and guest CentOS 5.5 inside VMWare with Mesa, and it works both ways. 1206 5 sgothel 2011-11-25 03:31:52 +0100 All test passed on CentOS, see bug 451, comment 3
