Thanks alot James. I managed to remaster Knoppix with Gnome using your scripts. I just edited 45xsession and knoppix-autocofig to make gnome the default window manager. I managed to get the CD to boot into gnome but when I install it on HD it did not start gnome. It says that it could not start kde because it is not the default window manager. I loged on knoppix account and typed "startx" and started into gnome. I checked knoppix-hd-autoconfig but did not see any thing says it should start kde. Do you have an idea what I should do to make sure the system starts into gnome automatically after HD install?
