I can't tell from the info you've provided whether you can actually
get logged in on the console.
If you can, try the magic "fix the terminal" sequence of
ctrl-j
followed (without pressing enter) by typing the command
reset
followed by ctrl-j. See the man page for tset and reset for more info.
If you *can't* get logged in on the actual console, try logging in
via ssh and then resetting the console via something like
sudo stty -F /dev/console sane
