Okay, because I HATE rumors I did the tests myself on SUSE 1.3.
The full screen display mode stuff as near as I can see is total nonsense.
JOGL uses AWT.
AWT goes fullscreen and sets the display mode just fine. Here’s the test code:
/*
test @(#)DisplayModeTest.java 1.4 01/07/17
@bug 4189326
@summary Tests changing display mode
@author martak@eng: area=FullScreen
@ignore This test enters full-screen mode, if available, and should not
be run as an applet or as part of the test harness.
*/
/**
* This test generates a table of all available display modes, enters
* full-screen mode, if available, and allows you to change the display mode.
* The application should look fine under each enumerated display mode.
* On UNIX, only a single display mode should be available, and on Microsoft
* Windows, display modes should depend on direct draw availability and the
* type of graphics card.

I don’t believe that LWJGL handles this significantly differently then AWT/JOGL. At the end fo teh day both must go through X to get to OGL.
). I have been trying to catch back up on the last few months of topics here but haven’t found much meat on a specific issue that’s outstanding in my planning right now. Basically, if I want to support Linux & Windows in full screen mode ( with safe Alt-tab to other apps and back ), is either JOGL or LWJGL a better choice considering both OS targets?
Thanks for taking some of your time to help clearing some fud. I’m trying to get my head above water with some work issues right now but will duplicate your test with my own environments as soon as I can.
