Linux Gnome Numeric Keypad Disabled [ Mouse keys ]

by Vivek Gite on December 28, 2008 · 24 comments

Q. I’m using Gnome under Ubuntu Linux and my numeric keypad is disabled. Pressing numlock key does not work any more. I’m not able to use numbers or special symbols from numeric keypad. Reboot does not help or using different keyboard does not help. However, numlock only works if I switch to text console by pressing CTRL+ALT+F1. Now, I’m dam sure this is related to X.org or Gnome. How do I fix this problem?
