I'm running xubuntu 12.04 on a 2007 macbook.

I'm using the laptop with external screen, keyboard and mouse. Yesterday after a dist-upgrade and after I unplugged the external keyboard I noticed that the Lapotop's keyboard was mapped to whatever (J = 1 , L = 3 , M = 0 e.t.c.) however I can login and type perfectly in the login screen and as a guest.

Any suggestions on how to get more information and/or troubleshooting are welcome.

This looks like your Laptop keyboard has an integrated Numpad. It is active when enabling NumLock.
Your Laptop Numpad might have small drawings of numbers on right part of your keyboard with the following mapping:
jkl -> 123
uio -> 789
m -> 0

Disabling NumLock should give back those keys their primary function.

  1. Hit Shift+NumLock several times to disable Numlock.
    You might also have a combination with the Fn keys depending on your Laptop model.

  2. If for some reason you are unable to get it done with your physical keyboard, this should help:

    1. execute onboard in a terminal. This will open an on-screen keyboard.
    2. click 123, then NumLock. After every click check if your Laptop keyboard is back to normal.

    NumLock key on the onboard keyboard (after hitting the 123 key)

I had this problem running Linux Mint. I plugged my external keyboard in again and pressed the numlock key to turn numlock off. Solved!

I found an answer to my problems with my Samsung keypad after it had been used with an external keyboard in which it does not function well. The instructions were given at Ask Ubuntu:

  • Put off the unit with the external keyboard and restart it with the external keyboard.
  • When the laptop is in the state ready to use, from the external keyboard simultaneously hit the keys NUMLOCK and SHIFT and try to hit a key which is lock before if it is reinstated.
