Hi! I have succeeded in compiling OpenJDK 1.6. I have just tested my modification and it does not work, I have the same behavior, no real fullscreen. As a first step, I used the same bug fix than in NEWT / JOGL 2.0 as it works in this demo on my machine: http://jogamp.org/deployment/webstart-next/jogl-demos/jogl-newt-applet-runner-angelesgl2es1.html
I used the binaries in jdk6/build/linux-i586/j2sdk-image/bin/, is it correct?
