Ubuntu - dkms - Remove modules

To remove a module (old ones are not automatically removed): 

sudo dkms remove -m nvidia -v 331.49 --all

or simply: 

sudo dkms remove nvidia/331.49 --all

NOTE: If the package dkms is removed the information regarding previous module build files is lost.

  • If this is the case, go through /usr/lib/modules/kernel_release and /var/lib/dkms/package_name and delete all files and directories no longer in use.
