Free BSD X window

Can anyone help me ?

I have installed Free BSD several times and I can't get the X window to work . I have installed the ports Gnome and others but for some reason when I type start x doesn't work.
I downloaded the 3 i386 disks but I get to install the first one wich complete the setup and everything is fine. I reboot and log in as a root , however can't get to install any X window.
I went to the free bsd site and I followed all the steps but it doesn't work.
I'll apreciate if anyone can tell me step by step how to get the X window to install in free bsd.

Best regards:)

Take a gander at the FreeBSD Handbook, Chapter 5. The X Window System | FreeBSD Documentation Portal

xf86config

Also note, the command is 'startx', with no spaces.
