Why can't I get a GUI with this LiveCD?

I have decided to try the Linux Distribution aptosid, so I decided to get one of their LiveCDs. I got the KDE i386 lite edition and put it in then booted it up.

It ran through all the initd processes and began starting up, made an attempt to start Xorg, then I was left at something like aptosid@aptosid:~$

I tried running “startx” with the error: “Failed to load module “nouveau” (module does not exist, 0)”

I am able to get other LiveCDs to work, it just seems to be this one.

Another problem that popped up is that my current Ubuntu 10.10 installation’s resolution changed to 640×480 for some reason. I tried reconfiguring xorg, but got no results.

Are the two issues related? Thanks for any responses you may have.

I am using the nVidia 9800 GT video card, by the way.
