[ltp] Keyboard issues with intrepid

[Phil Shotton]

So I hit reply, and started typing, and straight away got the problem. 
The following is the output from typing all the letter keys from left to 
right, top row to bottom.

Note that this is with a USB keyboard. I then moved onto the laptop 
keyboard, started typing, and everything was fine.
Moved back to USB keyboard, and it's all working. WTF is going on here?!
