I didn't see a reply to this thread (though I noticed you posted more

Fortunately all was completely corrected by going to a virtual
terminal and using the command

sudo dpkg-reconfigure xserver-xorg

and accepting all the defaults. Now all is fine on mine. (If it hadn't

a date so it's easy to restore.)
