Comment 5 for bug 227698

This bug is a duplicate of #31907.
I got a resolution to this in the ubuntu forum: http://ubuntuforums.org/showthread.php?p=5025680#post5025680
Resolution in hardy is to remove the package xserver-xgl which seems obsolete, and optionally switch to normal numeric keypad using System/Preferences/Keyboard/MouseKeys tab and unselect "Allow to control the pointer using the keyboard".
