I was having issues with the 304 nvidia drivers, so I decided to downgrade to the 295 drivers. I did so by dropping out of X, stopping lightdm, and installing the drivers. However, now my computer won't boot into Ubuntu at all. It hangs on
stopping anac(h)cronistic cron
and nothing happens. I have to manually shut it off. Booting into failsafeX mode doesn't work either. I'm writing this from a live USB because I can't figure out what else to do. Any ideas? Is there a way to purge the nvidia files while booted into the live USB?
