I recently installed the NVIDIA
319 driver from the Jockey window, and now X won't load! I'm stuck with a blinking cursor. I used to have the
304 drivers installed.
How do I fix this?
What happened is actually pretty common. You most likely did not uninstall the old driver.
You need to go and boot into recovery mode. Steps are below.
mount -o remount,rw /DO NOT FORGET THE
sudo apt-get remove nvidia-304 nvidia-settings-304
