Disclaimer: I am BRAND new to Ubuntu.
A quick background: my laptop hard drive crashed, I bought a new one, didn't want to pay for windows for an old laptop, installed ubuntu, it worked great for a week.
One day I booted up and logged in and got a black screen (no cursor showing as many have). I am able to log into guest just fine. Did my research --appears to be an issue with Nvidia drivers. There are many answers on how to deal with that (though I do not understand them yet).
Finally learned how to open the console/GUI/Ctrl+Alt+F1 (not sure technical name). I am prompted to enter a username and password. I can enter a username, but when I hit enter after entering my username, I am completely unable to enter a password. It will not let me enter a single character into the password, and after a few seconds it says the attempt fails, and loops right back to entering a username.
TL:DR I cannot enter any code to fix the NVidia drivers because I cannot get past my username and password. I know my username and password, but I am not able to enter my password.
I am fine with reinstalling the whole operating system, this computer is completely clean without any personal files, but I am unable to make any changes from the guest login because of lack of administrative permissions.
I am sorry if this is a duplicate, I have searched for a couple weeks and not found a situation exactly like mine, many similar though.
