Ok this didn't work , I don't know why it did seem to change what happens when it boots up but I still just get a black screen at the end of it all. is there another script or multiple scripts that it reads from when booting ?


You could change that by simply editing /etc/X11/XF86Config-4. I don't have a Knoppix-configured XF86Config-4 handy but for a standard XF86Config-4 I would just add the following:
