Help! Black login screen after update

[irishgrizzly]

After updating itunes and quicktime on my duel usb ibook I get a black login screen with lots of darwin type code.

After inputting my user name and password it just hangs. What can I do?

it means your in single user mode or have killed the GUI somehow.

does darwin use run levels? try innit 5 from the command prompt

Hope I've not killed the GUI

Is there a key combination that I can hold down on restart to get round this? I don't have any experence with code and would rather reinstall then mess round with it.

first call : Try Apple suggestions for startup problems:
http://docs.info.apple.com/article.html?artnum=106464

if that fails You should use "verbose boot" (hold down the Command and V keys after the chime) so you can see all the system messages scrolling by.
Pay close attention to see how far it gets.
