need some help with nvidia drivers ubuntu 10.10

[binatron]

I'm a first time Ubuntu 10.10 user (or any linux os). I've installed ubuntu 10.10 into my VirtualBox to try it out and possibly keep it as my main os. Everything went smoothly until i tried to install nvidia graphics driver for my gtx465 card.

I used these suggested steps to install the driver:
1) sudo apt-get install nvidia-current
2) reboot
3) sudo nvidia-xconfig
4) Log out and back in

After steps 1, 2, 3 i get an error "You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server". Now when i try to do the 4 step (logout and login back) to complete the process i can no longer get back to the desktop. I'm dead stuck in dos mode (or whatever it's called in linux).

I've googled quite a bit, found many different suggestions how to install, reinstall, remove, remove the nouveu driver and instal nvidia, etc.. but nothing helped. Commands startx, restart gdm and others which were suggested didn't work, but i get some error text:

"Failed to load the NVIDIA kernel module. Please check your system's kernel log for additional error messages."
"Failed to load module "nvidia" (module-specific error, 0)"
"No drivers available."
"Fatal server error: no screens found"
"xinit: No such file or directory (errno 2): unable to connect to X server"
"xinit: No such process (errno 3): Server error."

I've bricked about 6 backup installations of ubuntu 10.10 on my VirtualBox trying to get this to work so far and i'm totally out of ideas what to do at this point.
Need some help from an experienced user (just remember i'm a complete novice with linux nad need a very clear explanation ).

Virtualbox doesn't "pass" your real hardware through to the VM - it has pre-configured hardware that it knows how to emulate for the guest OS.

All those errors about "there is no Nvidia card" is because...there is no Nvidia card.

The lspci command will show your PCI devices.

I see. Didn't know it was like that. So what do i do about the graphics driver? My ubuntu resolution is currently 800*600 and i can't change it with or without the nvidia drivers (my native resolution is 1680*1050). Or is it normal for linux?
