title: How do you hide the mouse pointer under Linux/X11?
body: <p>How do I hide the mouse pointer under X11?  I would like to use the built in libraries in order to do this and not something like SDL (SDL_ShowCursor(0)) or glut (glutSetCursor(GLUT_CURSOR_NONE)).  Also, the mouse pointer should be hidden no matter the pointer location, not just in its own window.</p>
