Hi!
I think a more constructive approach (than only criticizing LWJGL) is to show you some examples of games that don’t work on my machine. I wanted to help another member to write a JNLP file that would allow to install LWJGL. I tried the example game “Space Invaders”:
http://www.lwjgl.org/jnlp/lwjgl-demo.php/examples.spaceinvaders.Game
I heard the sound (when I clicked) but I had only a black screen. I watched the Java console, I saw nothing except: “Use - fullscreen for fullscreen mode”. What can I do to? I get 62 FPS.
I’m under Mandriva Linux 2007, AMD Sempron 2600+, 2 GB DDR, ATI Radeon 9250 Pro with the Xorg driver.
I get this with the demo TestControllers:
[quote]Failed to open device (/dev/input/event1): Failed to open device /dev/input/event1 (13)

I don’t know why it happens but in AWT, most of my available display modes use BIT_DEPTH_MULTI and REFRESH_RATE_UNKNOWN.
I spent 40 minutes to make these tests, I hope it will help you to drive your API more reliable and now, you cannot accuse me of FUD. As you know, English is not my mother tongue. FUD means Fear Uncertainty and Doubt, doesn’t it?
N.B: Jake 2 LWJGL version works fine on my machine. Therefore, I assume GLGear doesn’t work because of a bug appeared in a LWJGL version younger than the one used in Jake2.
