If it's a hardware problem with typing the letter, it should always be typing it, not just when in Linux. Is the keyboard fine in Windows or if you use a Linux Live boot disk?

I agree with hang-the-9 that a hardware fault would show up on other operating systems. it appears the problem is with the way your keyboard or other driver is configured.
