Hi guys,

I recently uninstalled SusE 10.2 because I hated the new interface/wanted to try something leaner and I decided to go with Xubuntu. After installing the latest Nvidia drivers and adding Opera, pidgin, and getting some windows codecs, I decided I wanted to edit /etc/inittab as usual and change the default runlevel to 3.

However, when I ran It said I was writing to a new file. And sure enough, inittab wasn't in my /etc/ directory.

I also am having trouble booting into runlevel three altogether. I try, telinit 3 and init 3 as root and get nothing.

Thanks in advance.

You don't need it - the Ubuntu devs said so .... Search on "upstart"
The runlevels are (hopefully) the same as Debian; not like what you are used to at all I suspect.
Here's a similar query.

Ok, I think I understand the whole debian/ubuntu runlevels now but what is this upstart thing? I still don't know where/what to change so I can boot into Ubuntu's runlevel 1 by default, which I guess is runlevel 3 in SuSE/Fedora.

No,init 1 will (still) get you single user mode. Not the same thing, but may suffice - it does for me when I use/need it.
Can be added to the boot line, or you can create yourself an inittab - it'll be read.

As for upstart, begin here - you'll need to continue looking around to get the full picture.
