I am currently unable to load the desktop (ubuntu 13.10, AMD64) following installing 13.10, then trying to install the latest nvidia driver (x86-64-331.38) from tty (after having to stop lightdm). The installation failed (I do not remember the exact message); when I rebooted I was unable to start the desktop. Am I correct in thinking that the video driver is what is causing this?
Here's where it gets worse: I locked the root, so I am unable to uninstall/reinstall via root shell in recovery mode. All other options on the recovery screen end up hanging after a few lines (a known bug?). I have tried adding init=/bin/sh to the linux line in the grub file; I have access to a shell here but get a warning ("can't access tty; job control turned off") and I cannot (or do not know how to) run files.
My question is: is there anything I can do to restore the video without having to wipe the computer and reinstall everything? Can I start up from cd? I'm not sure if this helps but I have an ubuntu...iso file that I appear to have access to. I am happy to provide any additional information.
Thanks for any help.
