Hi everyone, I just remade a fresh install of my OS (Archlinux) and now I’m getting this problem in the engine.

Exception: java.lang.NullPointerException thrown from the UncaughtExceptionHandler in thread "jME3 Main"

Any idea of what could cause this?

(With any file, included the default main file of mygame package.)

Looks like a driver issue. The stack trace is coming from the Linux-specific LWJGL initialization… if LWJGL can’t init, something is very badly wrong.

I found a solution here: https://bbs.archlinux.org/viewtopic.php?id=221345

In my case I was missing this package xorg-xrandr.

Thanks for the gist anyway :smiley:
