I looked around the forums a bit and was able to fix it by following the directions to replace lwjgl.jar as instructed in this post. It now launches and runs fine.

I wanted to put this here just in case anyone else had this problem and so Red knows about this bug.

Thanks for your feedback It seems that the lwjgl fix actually works for Ubuntu. Can you eventually post your xrandr output here, just to compare it with other outputs and to see what's going on exactly (and why the fix is necessary at all)?
