Could not access root and user account after installing xorg-minimal

[ajith.comp]

I am running FreeBSD-9


After installing xorg-minimal  by 

 #pkg_add  -r xorg-minimal

and installing fonts by

#cd  /usr/port/x11-fonts/urwfonts
#make install clean

I installed Irsis.

The problem occured after I issued the  #startx , an error message appeared for a very short time.I could not read it.But think it was reading monitor.

Now I can not access any account.wrong password message appears after typing the password.


Thanks in advance.
