Answer 1

Depending on which LWJGL you're using, init your Display as shown bellow:

LWJGL 3 

if (!glfwInit()) {
   throw new IllegalStateException("Can't init GLFW");
}

LWJGL 2:

try {
   Display.setDisplayMode(new DisplayMode(800, 600));
   Display.create();
} catch (LWJGLException ex) {
   Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}

Please dont forget Display.create() .
