How to disable X11 autostart

Question

I have installed Solaris 9 and do not have any idea how to disable booting into X11 enviroment. I tried to find something in /etc/inittab (like in linux) but I failed.
Any idea?

You can mess with the rc scripts as much as you like.
Of course it is better to use tools like the DT configuration, as Lion mentions.
But nothing depends on S99dtlogn, especially that it is the last script to start. So you may modify its contents, rename, or remove it as you please.
There's a single script among rc files, which launches each S... and K... script with either Start or Kill argument respectively. So you rename the script to anything that does not start with these letters.
If I remember well, that single control script is started by some thing, which references svccfg database. svccfg is actually a utility that ultimately controls all startup, including the rc scripts.
You may use it to turn off any part of the start up. But I don't remember if it can turn off individual rc scripts. Anyway, you would break your neck trying to grasp the structure of svccfg database and the internal commands of this utility, because it is all text mode.
I personally would simply rename the file, or use DT configuration.
But I mention the svccfg for completeness of the picture.
svccfg may still come handy where scripting is required. You may want to study this utility and some other utilities related to it.
Some configuration can only be done with svccfg.
The behaviour of DT login, and configuration of its main screen can be done under /etc/dt/. You find original files somewhere under /usr/..., perhaps under /usr/dt/. Customize them and place under /etc/dt, as instructions in the files say.
