looks like you are selecting a wrong keyboard duringn installation. i did the same mistake when i was starting out with my mouse. selected a wheel mouse because it was a wheel mouse and the wheel was working in windows. but linux did some crazy stuff after the installation with my mouse. it used to jump around. so i had to configure it as a generic two button mouse and then it worked fine (of course the wheel didnt work)
so watch out if you are selecting a usb keyboard or not
