Gnoppix is quickly releasing new developer versions of its Ubuntu-based Live CD. This is version 0.9.9b1, a beta version, based upon the upcoming release of Ubuntu. This LiveCD will not take you directly to the Gnome Desktop environment, it will ask you some questions and you will be prompted with some dialog windows that will ask you about the language you want to use and your keyboard layout. After that and some hardware auto detection the boot of the graphical environment will boot.
