more simple Ubuntu questions

[Andres Gonzalez]

As you can tell, I am new to Ubuntu. The different root login 
architecture in Ubuntu I can live with--actually I think I kind of like it.

But where is /etc/inittab in Ubuntu?  Why is it not there?  Why can I 
not go from console mode to graphics mode using telinit?  In fact, why 
does telinit not seem to even work in Ubuntu?

I guess I am just learning how different from each other these distros 
can actually be.
