Thanks people.

One funny thing.

I was logged in as a user...

opened a bash shell, switched to super user

typed

shutdown now

and it shutdown the gui, and brought me to a command line....

I waited a while,,, then typed

shutdown now

and it after some scrolling text, it brought me to another command line, labelled single user mode.

so, I typed it one more time... and it worked...

heh.. maybe something wrong with my install?

well, thanks for info, I think I will live with it.
