How to detect driver problem in applet?

[darkmoon]

I have detected the following problem: on a system which has an unsupported graphics driver (according to other lwjgl games), the initGL and paintGL methods of AWTGLCanvas are never called.

When turning on debug, i get the following message:
Failed to lock surface, skipping paint(): org.lwjgl.LWJGLException: Could not find a valid pixel format
Pixel format not accelerated

I'd like to detect this situation and show a dialog, but there are no exceptions being thrown. Is there another way to detect this? I saw in the AWTGLCanvas paint method that this exception is indeed caught and not thrown up. Maybe in the case of driver problems it's better to throw it up?

are you specifying an "out of ordinary" pixel format?

In a case like this, you need to catch the LWJGLException, and retry with another pixel format...

It's an applet, so I'm just using AWTGLCanvas, without specifying any pixel foemat. I do catch exceptions, but none are thrown. The exception is caught in LWJGL code and not passed to my code. Sorry if I wasn't clear.
