I've had dualhead on a RH box before, yes, but not with that.

Lots of answers here. Mostly RH-specific. Even the final answer is
RH-specific in that some distros have different numbers/what they
do for the runlevels.

	(a) If you have linuxconf (which runs in X and in text mode)
    it's an option in there.
	(b) re-run Xconfigurator and the final question is "Start X on
    boot?" or something like that. Say no :) 
	(c) edit /etc/inittab. I don't have the X server starting
    on boot. My inittab looks like this. 

# Default runlevel. The runlevels used by RHS are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
# 
id:3:initdefault:

Editing inittab is of course what linuxconf and Xconfigurator do.
I suspect there's another way of turning it off via Nautilus, but
of course if X is dying, you won't get far trying that.
