This is upstream from http://forum.jogamp.org/Linux-Java-7-Dual-screen-issue-td4030862.html#a4031778 It seems that JOGL create context correctly only for one of the screens. When application windows is launched on “first” screen, content is shown and application is working correctly. But when window is moved to “second” screen window become is blank. No error is throw. When I move window back to “first” screen correct content of window will appear again. So in short Jogl application is working correctly only on one of the screens. This bug appear only when I try to run application using java 7. On java 6 application is working on both screens correctly. I'm working on Ubuntu 64 13.10, graphic card is integrated intel with jogl 2.1.4.  Work wrong on Java7 JDK 64 1.7.0_45-b18.  Work correct on Java6 JDK 64 1.6.0_45-b06.  Test case: https://github.com/sgothel/jogl-demos/blob/master/src/demos/gears/Gears.java In line 63 replace new GLCanvas(); with call of function: public static GLCanvas createCanvas() { // create a profile, in this case OpenGL 2 or later GLProfile profile = GLProfile.get(GLProfile.GL2); // configure context GLCapabilities capabilities = new GLCapabilities(profile); // setup z-buffer capabilities.setDepthBits(16); // for anti-aliasing // FIXME cause problem: capabilities.setSampleBuffers(true); capabilities.setNumSamples(2); // initialize a GLDrawable of your choice return new GLCanvas(capabilities); } When setSampleBuffers and setNumSamples is comment out application is working correctly, but when un-commented application freeze. This example freeze on both screens but my application (kendzi3d) freeze only when moving to second screen. In both case commenting out of setSampleBuffers and setNumSamples solve problem. 3832 1 605 kendzi 2014-03-06 00:14:20 +0100 Created attachment 605 TestCase 3940 2 kendzi 2014-06-03 23:26:39 +0200 Any
