I am really happy with my customization but now am blocked: I have to enable kdm or xdm to control the access.
It works in chrooted environment but not on the burned image.
Tried to launch kdm in /etc/init.d/xsession (after X is started) but with no success (nor with xdm)
Any help by you gurus would be really appreciated.

Knoppix is GREAT !
