Hi!

I've bypassed the problem by manually checking for VBO's, but this behaviour is strange. It reports GL 1.5 is available but VBO's not, which shouldn't be possible - anyway the newest GLX is for GL 1.4, so i think isGL1.5 is looking at different GL context than the application uses ( application must use GLX server context on the other machine, because I've exported the display )

Here is the stack trace:

> export DISPLAY=192.168.100.108:0.0 ( other machine, 32bit ubuntu )
> xlogo ( works fine )
> glxgears ( works fine )
> java -jar -Djava.library.path=/home/barcsik/Workspace/NetBeans/3D\ Surface/lib/natives-linux-amd64 3*
