Whenever I try to bring Minecraft into fullscreen it just stops and says something like failed to write core dump. This doesn't happen when I maximize it though.

I thought it would just open up to fullscreen.

Instead it just stops.

Steps to Reproduce:
1. Bring up Minecraft Launcher on computer specified above.
2.Switch to version 1.8.1.
3.Click Play.
4.Wait for it to get to Minecraft Title Screen.
5.Press Fn and F11 at the same time.
