lwjgl 2.4.2 fails on linux

[raft]

hi,

hello world GL example in latest release (1.21) doesn't launch. it throws the exception below. it runs ok in previous versions including 1.21 alpha. i guess this is related to LWJGL 2.4.2

Looks like as if it fails on this call:

Code Select Expand


Display.getAvailableDisplayModes();


because that's the only lwjgl related thing that GLHelper.findMode() does. Maybe you can write a simple test case that does this call and see what happens then!?

[raft]

yes, that call fails with same exception

Code Select Expand

Looks like an issue for the lwjgl forum then...
