How to reinstall the default graphics drivers in terminal and without internet

Question

I accidently remove the graphics driver (I did something like apt-get remove --purge fglrx* and other things, I don't really remember) and now my computer boot to a console login page.

Now without GUI I cannot connect to wireless internet and so cannot install anything.

Can I revert to the initial graphics driver (and configuration)? Maybe with an installation CD? I have Ubuntu 13.10.

I tried sudo-apt-get install --reinstall fglrx, it did install, but when I tried fglrxinfo, it gives

Error: unable to open display (null)

The initial graphics driver is the open source xorg drivers included by default. Boot into recovery mode, then select to drop to a root shell. Execute mount -o remount,rw / then make sure you've fully removed fglrx with apt-get purge fglrx -y and rm /etc/X11/xorg.conf then reboot.
