[Newbie]X86 Log in

[Troy Rau]

I have the FreeBSD 4.2 installed, and when I log in, it goes into the Command line version fine.  I can navigate around and do whatever, but when I try and run the X86 GUI(xdm), it goes to a graphical login screen and prompts to log in again.  I enter the login and password, or goes black for a second, back to the grey screen, and right back to the login prompt.  I can never get it to run.  Any ideas?   Troy
