If you have nano (or another favorite editor), at the C prompt, execute the 
following line: "nano -w /etc/X11/xorg.conf" . In the "Monitor" and "Screen 
sections, change monitor 0 (zero) to one and monitor 1 to 0 (zero). This 
change must be made in both Screen and Monitor "Sections" of the xorg.conf 

When finished, press Ctrl and x keys simultaneously, say "yes", press Enter, 
and the file will be saved and closed (this is with nano). Run startx and 
check-out the results.
