How to uninstall manually installed Nvidia drivers?

Question

How do I uninstall manually installed Nvidia drivers 310.14 and revert to Noveau. I have Ubuntu 12.10.

Answer 1

Yeap, was going to say what Karasu said. Just to add some information. If the driver you downloaded is called for example NVIDIA-Linux-x86-310.19.run then you would run:

NVIDIA-Linux-x86-310.19.run --uninstall

If you want to get the help for yout Nvidia driver then do this:

NVIDIA-Linux-x86-310.19.run --help or a more extended version for it:

NVIDIA-Linux-x86-310.19.run -A which shows you the uninstall option:

--uninstall
  Uninstall the currently installed NVIDIA driver.

There are a couple of other nice options in case you want to use them like:

-a - Accept Licence
-s - Silent Mode
-q - no questions
-i - Driver information
--update - Check Nvidia site and update to the latest

Answer 2

First you need the installation file. Then put it in your home folder, open a terminal and type

sudo ~/installation_file.run -uninstall

Then restart your computer and your drivers will be completely uninstalled. If Unity won't load after the uninstallation right click-->change desktop background then click on "All Settings" on the left-top corner of he window, go to Software sources and install a propietary driver from the list.
