Re: disable GUI/X?

[Hans <hans.ullrich@loop.de>]

Just remove any login-manager like gdm, kdm, sddm and lightdm.

For testing purposes, you can eaily remove the binaries below /usr/bin/ to 
somewhere, for example to /root/.

Then reboot and it will not boot into X. Startx will work. 

And if this is not what you want, just move the binaries back to /usr/bin/, 
reboot and X is starting at boot again.

Hope this helps.

Best

Hans
