I am using your basic example (doesn't draw anything, just clears the screen). If I use: Gdx.app.setLogLevel(Application.LOG_DEBUG);

Then when exiting the app, it core dumps:

MyGame: create MyGame: Detected Desktop application MyGame: pause MyGame: dispose #

A fatal error has been detected by the Java Runtime Environment:

#

It does not core dump unless I use the setLogLevel with LOG_DEBUG.

I would suggest to use stable version of Java. Most libGDX games are probably written in Java 6. Java 7 syntax is not fully supported in Eclipse IDE yet and it seems that you're even using developer preview release of Java 8.

Looks like it may be LWJGL related http://lwjgl.org/forum/index.php?topic=4526.0

Hm, hard to tell. Tested on a Ubunut 10.04 32-bit install in Vbox, no problems there.

C [libX11.so.6+0x35c08] XQueryExtension+0x28 this indeed indicates that something is borked in the communication with X11. Hard to tell how to fix it though, we rely on Lwjgl to do the dirty work.

Will try to get some Lwjgl people to look at it.

This should have been fixed in the latest LWJGL release which we incorporated in 0.9.6 and above.

Not fixed, still happening with current nightlies.
