Last, search for the nf file and remove it as well sudo rm /etc/X11/nf 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 With purge command it should UN-blacklisted. So after above command you should also give the installation command for ubuntu-desktop package sudo apt-get install ubuntu-desktopĪlso sometimes the nouveau driver get blacklisted from nvidia driver. * in the end means (Purge everything that begins ( ^) with the name nvidia-)Ībove command will also remove the nvidia-common package and the nvidia-common package has as a dependency the ubuntu-desktop package. 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-.*' dpkg -l | grep -i nvidiaĮxcept the package nvidia-common all other packages should be purged. Search what packages from nvidia you have installed. No need to blacklist something, but sometimes maybe a force-load of the nouveau module needed.

If you remove -purge the nvidia driver you will be OK. You can open a terminal with Ctrl + Alt+ T keys combo.
