What you have to do is that is none that's just some sort of serious bugs got on 11.10 version it's deficient on some kernel core so kindly use any ubuntu lts(long term support) like ubuntu 10.04 or upgrade to 12.04 even though in 12.04(precise pangolin)several crucial errors like net connection ,wifi, graphics kernels are missing out but even though 10.04 is older it works flawless with every kernels try it :)

Your Fn key was stuck down. On a Samsung R480, and most other laptops without a separate numberpad, Fn + those keys act as either Page Up, Page Down, Home, End, Ins, Del, or the arrow keys, if Num Lock is off.
