Please tell me how to reset my screen-resolution or reinstall Ubuntu via the terminal

How are you? My name is Chad Syphrett. I'm a new member of this online-community, so like most newbies, I need help solving a common problem, which most new users of Ubuntu seem to need help solving. I need someone to tell me (step-by-step instructions about how to either reinstall Ubuntu via the "terminal" or fix my screen-resolution via the termiinal.

I'm using a Dell Inspiron 531s with Ubuntu Linux 7.10 [Preinstalled]
Type: AMD Athlon 64 X2 3800+ Processor
Model: WL400GSA1672
Video-Card: Integrated NVIDIA GeForce 6150 LE Graphics
Including: VGA Output

Important note:

I've been using a LCD Monitor: "HP Pavilion f1503" for that computer

When I started my new Dell computer (with Ubuntu 7.10 preinstalled ), Ubuntu loaded within 1 minute, and as soon as the "Installation-Wizard" window was displayed on my LCD monitor a warning message (seen below) appeared:
PC video resolution setting is out of range
Change setting to Recommended resolution

I changed the display-settings to the "recommended resolution", and restarted my computer, then after Unbuntu's login window appeared again, the text within the the Ubuntu GUI was completely illegible (meaning: the login-page and everything else on Ubuntu, such as the desktop image & icons were completely blurry, overlapping each other in a tile-like pattern).

The person, who sold that computer to me told me to restart my computer, wait for the Ubuntu login-page to appear then push Ctrl+Alt+F1 to make the terminal open, then type the following commands:

sudo nvidia-xconfig
Ater I typed all of that in the terminal, I got this error-message: "command not found". Please tell me what I did wrong & what I need to do to solve this problem.

reset screen resolution

Ok, first of all, when you hit Ctrl+Alt+F1 to have access to another terminal, I believe you're trying to type a command that doesn't exist simply because Nvidia drivers are not installed yet (that's why the output message is «command not found».

So my advice here is to type
sudo dpkg-reconfigure xserver-xorg
you'll be guided to several steps where you can reconfigure your keyboard, mouse, display driver and screen resolution.

My suggestion is to go through those steps and, if your keyboard and mouse are correctly set, just don't change them, just leave them as they are.
With the display driver you should look for one called «nv» or, if you don't see it, just pick the one called «vesa», it usually works for any display and for me, it's the one that get's me out of trouble

After that you can choose what you'll find to be the correct screen resolution.

When all this is done just logout (you don't have to restart, I think!) and hit Ctrl+Alt+F7 to return to the GUI interface (not terminal).

Hopefully you can manage the installation of the correct driver for your graphics card within Ubuntu GUI.
