Hrm, it seems to be crashing on Display.getWidth(). But Display.getWidth() is part of LWJGL, a third party library most Java game developers user for OpenGL bindings.

Do you have any trouble running other Java based OpenGL games, like Minecraft, Project Zomboid or Towns?

I have had a few isolated reports that LWJGL has trouble getting the Display's width/height in some multimonitor or custom configurations in Linux. If you have anything out of the ordinary, like an overclocked monitor, you could try resetting it back to default.

There was one bug report a while back where the user's second monitor was confusing OpenGL (or OpenJDK), when he unplugged the secondary monitor RPC booted up just fine. Obviously that's not an ideal situation, but at least we can get the game running. :)

Some other options you can try;
- Try running the game directly, via RetroPixelCastles.sh or core.jar
- Try installing Oracle's JDK instead.
- Update the graphics drivers. It's possible your version may have a stray OpenGL bug.

Thank you!

Problem was resolved with install xorg-xrandr
