Last night I as trying to update the flash player plugin, by following the steps from here.
sudo apt-get install firefox ubuntu-restricted-extras
Because the connection was slow and I was remaining without power, I've tried to cancel the command. It didn't get canceled so I've closed the terminal window and shout down the laptop.
Now, I can login as a root and I have access to the terminal but it has a lower screen resolution. Also I've lost wireless and wired sections on System Settings->Network.
I'll like to know if I can restore Ubuntu to the previous system state? Can I do it from the damaged state or from a LiveCD? Which is more safety?
