Start with 
sudo apt purge *nvidia*
then run
sudo dpkg --remove --force-remove-reinstreq x
where x is the dependent output from the previous line
should end up with something like:

sudo dpkg --remove --force-remove-reinstreq cuda
sudo dpkg --remove --force-remove-reinstreq cuda-9-2
sudo dpkg --remove --force-remove-reinstreq cuda-runtime-9-2
sudo dpkg --remove --force-remove-reinstreq cuda-demo-suite-9-2
sudo dpkg --remove --force-remove-reinstreq nvidia-driver-396
sudo dpkg --remove --force-remove-reinstreq cuda-drivers-396
sudo dpkg --remove --force-remove-reinstreq nvidia-driver-396
sudo apt purge *nvidia*
