Cannot start X

[Michael L Ried]

I cannot start up X windows after using the startx command.  It looks
like X windows is going to start but then it stops soon after starting
up.  I am not sure if there is some place to look for error messages.  I
assume that I didn't entered something incorrectly when I ran XF86Config
but I am not sure what it is.  What should I do now?
