Re: difficulty installing Lubuntu
http://forum.linuxmint.com/viewtopic.php?f=46&t=63805 seems to say that this laptop probably has limited RAM. Do you have 512MB or less?
At that link, the person waited 30 minutes to see the Mint desktop.
On a RAM limited machine, I'd recommend installing Ubuntu Server, then install a minimal LXDE desktop.
You will be at the shell, which is what happened above. Some might call it a terminal or CLI, but a terminal is usually a program, not just the interface.
On an extremely limited PC with less than 512MB of RAM, Ubuntu (any type) is probably not the best desktop version. I'd recommend that you check out TinyCore. I used to recommend Puppy Linux, but running as root all the time just seems "wrong" and lazy. Linux developers should know better.
I believe the default F/LOSS video drivers should work fine on your hardware. No need to install proprietary nvidia drivers.
Sorry I'm not any real help with a point-n-click answer.
