Can't startx more than once

[link1305]

I've been using Gentoo for about a month and I like it so far. I have a strange problem though...when the computer powers on it's at the normal text login, then I can login and type startx and KDE starts like normal. Once I quit KDE I can't reenter until I restart the computer. When I try to type startx, it says command not found....it does the same as root or a normal user.
