Ubuntu blank screen on startup
Okay, first of all, I'm a completely new Linux user and pretty unfamiliar with the command line so any step by step help would be the most useful.
I've just recently installed Ubuntu Linux (Breezy 5.10), I'm dual booting with Windows XP on my Toshiba M70 laptop, but I'm having some trouble. When I choose the Ubuntu OS in the Grub bootloader, everything seems to go pretty well, the Ubuntu logo appears along with various status messages which scroll underneath. The status bar reaches full and then the system just stops on a totally blank black screen after briefly displaying a blinking cursor in the top left. Nothing happens. I can use ctrl+alt+f# to reach a login, but I have no idea what to do from there.
I must also mention that I did not configure the network during Ubuntu's installation, and the status messages display a message stating that a connection to ntp.ubuntulinux.org has failed.
Thank you for any help you can offer! I would really like to get this working soon.
