Finally I got this Java3D application running. But... it runs on my own computer and not on the target computer. The target computer runs the app fine until the moment it has to display 3D, then the 3D picture is only a white area. I know Java3D is quite picky about the GLX mode or visual mode. If certain GLX modes, (double) frame buffer or color depth is not supported, it doesn't run Java in 3D.
I also started the Java3D app in debug mode which shows all the GLX modes tried and accepted and which not. Both computers give the same error messages, but on one of them Java3D eventually produces a display.
Both computers have an NVIDIA card, both run glxgears, glxinfo give the same output... so I thought. Running glxinfo and finding the diff gave this slight difference:
Code:

The
RED lines are from the non-working card, the
GREEN lines from the working card. As you see there is a difference, the working card is Geforce4 and the non-working card is GeForce2.
Now this is a shame, this hardware is only 7 years old, I am not running Winblows so I have to upgrade hardware every three years!
Still there is a slight chance that I should upgrade the VGA card. This one is almost the cheapest I found, I prefer passive cooling. I also like to stick with NVIDIA, so far Linux support has been very good.

It is a FX5200. The thirty-five dollar question is: is this chip already better than the GeForce4, and is it likely to run GLX in a way that Java3D is supported?
