[newbie] No Penguins on login screen.

[deranged--hermit]

I am using Mandrake 7.1

Somehow I did something to my linux box and now I don't have the penguins on
the login screen.  I am reffering to the penguins that represent each user. I
used to have a root penguin and my username penguin on this screen.  I can
still login just fine the only difference is that the penguins are gone.

Can someone tell me how to get the penguins back?

Thanks in advance;
