Your exception very much resembles mine. A Blackdown developer tracked it down and described it as an GeForce specific bug.

Well, since this is a Java3D specific question in the broader sense, I can answer on this list :-) Try to get and run "screen". Using this utility, you get virtual consoles. You log on remotely (via ssh), run screen, start X in a screen console and 'detach'. When detaching, screen is continued and so are all the apps you started within a screen console. You log off. Later, you log in again, re-attach to screen and stop X. It's all in the man pages. I have a server running doing exactly what you describe. He uses Java3D for rendering and makes the rendered JPGs available. He is remotely administered using ssh/screen. check out http://www.walkmap.de B. || || Thanks, || Pasi || || || || ----- Original Message ----- || From: "Bernd Fondermann" <[EMAIL PROTECTED]> || To: <[EMAIL PROTECTED]> || Sent: Thursday, February 27, 2003 10:28 PM || Subject: Re: [JAVA3D] Off screen rendering with Linux J3D 1.3 || || > Pasi, || > || > Sorry for late response. || > || > Sounds like you are using a nVidia Card...?! || > This is a known bug in the Blackdown Java3D implementation with those || || specific || || > types of GPUs.
