I am brand new to the Ubuntu community and am already in trouble. I recently purchased a new system76 ratel performance desktop with pre-loaded Ubuntu 13.10. Upon first start of the system, no video output was displaying. I turned the system off and tried again using a DVI cable and the video output came through perfectly. However, rather than running me through the install menu, I was sent directly to the login screen. I was never asked to create a username or password and can only log in as a guest. How to I go back to the install 'wizard' and create a main user? I would greatly appreciate your assistance as I am so stoked to get this thing working and my nerves are being overtaxed trying to figure this problem out. Thank you in advance.
