Numeric keypad stopped working in Ubuntu

My laptop's keypad stopped working.  There are two solutions:

1. System -> Preferences -> keyboard -> uncheck "pointer can be controlled by keypad" under the "Mouse keys" tab
2. gksudo gedit /usr/share/X11/xkb/compat/complete
   and comment out lines for mousekeys and accesx(full) (for full keyboard accessibility purge)
   resulting file /usr/share/X11/xkb/compat/complete:
   // $XKeyboardConfig$
   // $Xorg: complete,v 1.3 2000/08/17 19:54:34 cpqbld Exp $
   default xkb_compatibility "complete" {
   include "basic"
   augment "iso9995"
   //augment "mousekeys"
   //augment "accessx(full)"
   augment "misc"
   augment "xfree86"
   augment "level5"
   };
