Login from the terminal mode console you found.  Use command:

sudo dpkg-reconfigure xserver-xorg

will create new settings for Xserver.  You should be able to accept all 
default values to the prompts.  I think either --priority=medium or 
--priority=high will just auto-generate the configuration without asking 
you anything (same as a fresh install)
