DoudouLinux CD

I get past the DouDouLinux Hello page, from live cd; I have tried without persistence & first line of Start DouDouLinux; I get as far as starting dansguardian, then stopping dansguardian, starting http squid & maybe stopping http squid; then I get at a dos prompt: xset: unable to open display. If I wait I get to a window asking if I want to view the X Server error log; which says something like no display found. I have a dual-boot WinXP Pro SP3 & LinuxMint 9, both with all updates, AMD Athlon 64X2, 4GB RAM, iMicro plain/generic LCD 19" display monitor, NVidia graphics board w/latest update, I use generic monitor settings as the NVidia settings don't seem to save or work-not sure which. I have searched & found that the NVidia displays have issues with DouDouLinux. Is there any work around? Once I get to the command prompt of tux@doudoulinux: anything i can do or commands to use?
