Linux + JOGL

Hello,

I’m under Linux, with a ATI 9600 Pro, and Gnome as a Desktop Manager, and Java 1.5.0.3.
The demos found at https://jogl.dev.java.net/ don’t work anymore for me.
They did a few days ago : just a click on the pic of a jogl demo, and Java took the hand, and played it for me.
But since I’ve changed my GFX drivers (ATI’s now, and default drivers before that) and upgraded from firefox 1.0.3 to 1.0.4, it’s not working anymore.

How should I do to have them working?
I’m asking 'cause I’m interested in developping with JOGL!

What’s the error? Does Java Web Start get launched at all, or do you get an exception in the Java console? If Web Start doesn’t start up, the simplest solution is probably to reinstall the JDK. If it does, then enable the Java console in Java Web Start (run jre/bin/javaws and enable the console and logging) and please post any exceptions that are thrown during startup.
