problem getting back into pro-7.1

Some of the typed lines in in x windows in my pro-7.1 were either cut off in the middle if the typed line or even looked as though they were even hand written. I ran sax2 in order to hopefully fix that and now my mouse pointer is a big square and I have no control in x windows. I am trying to figure out how to turn off x windows but have not been able to get into the unix like text environment and really don't want to reload for 10 hours again. Does anyone know how I can get back into my system without reloading? Also how can Xwindows be kept from automatically starting?
