I upgraded to 12.04 today from 11.10 from a bootable thumbdrive. The upgrade took approximately 8 hours. I had to make a new user, and I'm unable to sign into my user that I used in 11.10. I can see my files in the /home/ directory, but there isn't an option to sign into that user on the boot screen. I am also unable to use the normal "Ubuntu" setting, I get a black screen with that. I have to use "Ubuntu 2D". Please help.

You have a permissions problem.
What you need to do is get to a terminal as explained here, and sign in with your username and password.
Then, you need to run the following:
sudo chmod -R 750 /home/$yourusername
Then, type:
sudo reboot
to restart your computer.
Once that's done, you should be able to log in via lightdm.

When I push Ctrl-Alt-F1, my monitor goes blank with a "Sync out of Range" error. Ctrl-Alt-F7 brings me back to the desktop. Does it have to be one of these weird terminals? Can't I just use the "Terminal" app? May 1, 2012 at 12:47

When I tried that command in the normal terminal app, it corrupted all my files and I had to do a clean reinstall. May 3, 2012 at 20:15

@Seth Yes, you have to do it in the 'weird terminal'. Otherwise, what you had happen happens.– jrgMay 4, 2012 at 1:24

A workaround could be : move you old user folders and files to your new user home.
If you want to keep all your setting you must view the hidden folders from nautilus (view > show hidden files) then copy the hidden folders of your choice AKA application you will still use.
Copy/Replace the entire usr/previous user/home with your new /usr/current user/home
Go to user a/c and delete the old one with all files
