XWINDOWS is giving me a problem

[Bob Falanga]

I ran /usr/ports/UPDATING which took all day. When I was finished I started
xwindows and it worked fine, so as usual I shutdown the machine. Later when
I restarted the computer and tried to restart xwindows it would not start
but gave me several errors, the log is included below:
     Jan 19 12:23:49 twcny kdm-bin[754]: X server for display :0 terminated
unexpectedly
Jan 19 12:23:49 twcny kdm-bin: :0[758]: IO Error in XOpenDisplay
Jan 19 12:23:49 twcny kdm-bin[754]: Unable to fire up local display :0;
disabling.

HELP    Thank you,
