As expected, Nvidia drivers have reduced my customizations. I can't login to Unity 3D session. I can't find any content to help me to uninstall the driver and I don't know what to do as I have never uninstalled them before.
For Ubuntu 12.04
Commands can be executed to terminal. You can open a terminal with Ctrl + Alt+T keys combo.
remove --purge the nvidia driver you will be OK. No need to blacklist something, but sometimes maybe a force-load of the nouveau module needed.
First uninstall completely the driver.
Search what packages from nvidia you have installed.
dpkg -l | grep -i nvidia
except the package
nvidia-common all other packages should be purged.
If you want to be sure that you will purge everything related to nvidia you can give this command
sudo apt-get remove --purge '^nvidia-.*'
.* in the end means (Purge everything that begins (
^) with the name
above command will also remove the
nvidia-common package and the
nvidia-common package has as a dependency the
So after above command you should also give the installation command for
sudo apt-get install ubuntu-desktop
Also sometimes the nouveau driver get blacklisted from nvidia driver. With purge command it should UN-blacklisted. If you want to be sure that nouveau will be load in boot, you can force-load it by add it to /etc/modules
echo 'nouveau' | sudo tee -a /etc/modules
Last , search for the xorg.conf file and remove it as well
sudo rm /etc/X11/xorg.conf
sudo apt-get remove --purge '^nvidia-.*' sudo apt-get install ubuntu-desktop sudo rm /etc/X11/xorg.conf echo 'nouveau' | sudo tee -a /etc/modules
Although all above commands not needed, this is my way to completely purge the nvidia driver and use the open source nounveau.
I realize that this is an old answer, but I have to add an answer here for sake of clarity and system stability.
First off, the
* is an expansion operator for the shell which will grab everything and remove a lot of files you don't need to remove. The safest way to remove the nvidia driver is to do
$ dpkg -l | grep nvidia
Search for nvidia-xxx.xx version or nvidia-driver-xxx.xx version and then type
$ sudo apt purge nvidia-xxx.xx
It will only remove that package but will also flag its dependencies for removal.
To remove the dependencies is easy.
$ sudo apt autoremove $ sudo apt autoclean
So for example, if you have the 390.xx package installed, it would be.

To verify, you can do
$ apt-cache search nvidia | grep driver nvidia-settings - Tool for configuring the NVIDIA graphics driver ubuntu-drivers-common - Detect and install additional Ubuntu driver packages vdpau-driver-all - Video Decode and Presentation API for Unix (driver metapackage) xserver-xorg-video-nouveau - X.Org X server -- Nouveau display driver nvidia-340-dev - NVIDIA binary Xorg driver development files nvidia-384 - Transitional package for nvidia-driver-390 nvidia-384-dev - Transitional package for nvidia-driver-390 nvidia-driver-390 - NVIDIA driver metapackage nvidia-utils-390 - NVIDIA driver support binaries xserver-xorg-video-nvidia-390 - NVIDIA binary Xorg driver bumblebee-nvidia - NVIDIA Optimus support using the proprietary NVIDIA driver kubuntu-driver-manager - Driver Manager for Kubuntu kubuntu-driver-manager-dbg - Driver Manager for Kubuntu -- debug symbols nvidia-common - transitional package for ubuntu-drivers-common nvidia-304 - NVIDIA legacy binary driver - version 304.137 nvidia-304-dev - NVIDIA binary Xorg driver development files nvidia-340 - NVIDIA binary driver - version 340.107 nvidia-387-dev - Transitional package for nvidia-driver-390 nvidia-387 - Transitional package for nvidia-driver-390 nvidia-390-dev - Transitional package for nvidia-driver-390 nvidia-390 - Transitional package for nvidia-driver-390 nvidia-driver-396 - NVIDIA driver metapackage nvidia-utils-396 - NVIDIA driver support binaries xserver-xorg-video-nvidia-396 - NVIDIA binary Xorg driver
Once you've targeted the package to remove, do
$ sudo apt purge nvidia-390 -y $ sudo apt autoremove -y $ sudo apt autoclean
Make sure to install whatever driver you plan on using right after you do this and if you don't have livepatch because of whatever reason, just reboot your system and you should be good to go.
This way you don't ever have to worry about removing system dependencies while clearing out your drivers. You'll have a sane and stable system afterwards and don't have to worry about re-installing other packages that your system may depend on. That's
apts job, not yours.
If you have only access to GRUB:
- Restart your computer
Advanced options for Ubuntuat GRUB Boot Menu
Ubuntu ..... (recovery mode)
dpkgRepair broken packages at the Recovery Menu (this will stop the nvidia processes so we can uninstall). Choose Yes. When finished press ENTER (even if it found problems)
root(Drop to root shell promt at the Recovery Menu)
- Type your root password
apt-get remove --purge nvidia-*
- If finished type:
- Boot as usual, it should go to your Ubuntu Login screen now
I didn't want to modify
/etc/modules, and just revert to an install without the nvidia drivers. So I mostly did as the accepted suggested, but instead of the last step, I do this:
sudo rm /etc/modprobe.d/blacklist-nouveau.conf sudo update-initramfs -k all -u
So my variant summary:
sudo apt-get remove --purge nvidia-* sudo apt-get install ubuntu-desktop sudo rm /etc/X11/xorg.conf sudo rm /etc/modprobe.d/blacklist-nouveau.conf sudo update-initramfs -k all -u
