Gentoo - Gentoo problem with setting up Xorg

I'm trying to set up my Gentoo with Openbox, but it's only booting into TWM and I thought I did everything that the handbook said.

My .xinitrc only has:
"exec ck-launch-session openbox-session"

and the last line of my inittab is:
"x:a:once:/etc/X11/startDM.sh"

My autostart.sh has the example things removed except the lines for XDG and the background, and "tint2 &" added
