Hi,
I hope this helps.

Boot to your SuSE OS.

logon as: root ( as you need root permisions to do this )

Change to a shell by selecting CTRL+ALT+F1 through F6.

Have your software ready.

run Yast.

select: System administration

and then: Configure XFree86

You should be able to disable X11 from there with a check in the box next to that text.

Good luck.

I'm sure there is a way to do this from KDE without having to go through what I just sugested. but you need to be logged on as Root anyway.
