I'm running a 2.2Ghz Intel Core 2 Duo MacBook with a NVidia GeForce 8600M GT graphics card.  Does anyone know why lwjgl can't recognise my hardware?  -I've also noticed slowdowns under an older version of JOGL that suggested software rendering was being used.

Also, is there anywhere I can get example app code for the latest version of lwjgl, since the Display class seems to have lost most of it's functionality since the available tutorials were posted, and are badly out of date?  Thanks in advance.

it IS finding a graphics card - it just doesn't know which it is (missing impl for native mac - afaik, only windows has this ...)
All of the code under org.lwjgl.test.* works - and some serve as demos at http://lwjgl.org/demos.php

Whoops!  -My mistake.

Yes, but I meant in terms of actual source code- the stuff online (e.g, here) uses Display class methods that don't seem to be there in the latest version, e.g:
1  
2  
3  
4  
  213       setDisplayMode();
  214       Display.setTitle(WINDOW_TITLE);
  215       Display.setFullscreen(fullscreen);
  216       Display.create();

Or have I made some ill-considered newb blunder again?   Sad

Wait- I see the problem.  I'm importing org.lwjgl.util.Display, as opposed to org.lwjgl.opengl.Display- frack.  Sorry to bother.
