Got a problem that occurs with the iMac DVs at the College I work at - sometimes (randomly) when I'm passing an iMac I notice the screen is filled with a darwin interface. It lists something every 5 or so seconds, stating something could not be initialized or something (i forgot to write down what it said 
)
It seems to occur when people log out, as far as i know.
If I type root it asks for my password, which I give then I can use the interface. Problem is I dont know how to restart the computer from this. I've tried exit, logout, quit, restart. The first 3 switch off the darwin window and bring up a blue screen with the circular bar ticker (that you get when you start a mac up on the grey screen), then it goes back to that screen.
I tried shutdown command but it asked me for some more info and I'll be the first to confess that I have no idea what I'm doing!
The only solution I can find at the moment is to hold the power button to switch off the mac, then start it up again. If you need any more information let me know.
