in your console... or where ever you can type in commands right now...
this will open up the man page telling you how to use your inits
I think init 3 takes you to regular default console mode (no X server running)
You can also check your /etc/inittab
file for the line that says:
# The default runlevel is defined here
is the part you want to look at.
The 5 is the init level to start on bootup. If you are going straight into GUI (x srvr) then you are most likely defaulting to init 5 (i think... correct me if i'm wrong) depeding on the distro too.
If you want to boot straight to the regular console and no X srvr replace the 5 with a 3. OR, you can just type:
as root and it will switch to runlevel 3.
hope it helps.
