I have been using ubuntu for a month and until now there were no problems. After I ran the automatic updates last night,today ubuntu can no longer boot, even with Ctrl+Alt+F1. I can't boot to run commands.
Tried everything from recovery console, I entered command shell from recovery console (I think that is the right term) to try and add these commands I found on the ubuntu help forums regarding nvidia drivers:
sudo apt-get purge nvidia-304 and
sudo apt-get nvidia current, but it doesn't recognize these commands. So basically after starting computer all I see is a line that keeps blinking and nothing works.
