If it's a bit old and battered, perhaps you should check the cable and/or connector?

I've tried a variety of keyboards, & this is basically a newish PS/2 keyboard that I plugged in when I first struck the problem with a Ubuntu upgrade.
I am certain that the issue has nothing to do with the actual keyboard itself. It is a motherboard issue. This same keyboard & others all work fine on other distro's & versions of Ubuntu, with the exception so far of Edgy, Feisty & Sabayon 3.4a, I don't know about previous versions of Sabayon as I have not tried them.
