I found that the process of removing nvidia driver / returning to nouveau is prevented by a running service (nvidia-persistenced). to get rid of the proprietary driver, do: "sudo kill <id of process>" and then you can use the hardware driver dialog to return to nouveau. To find the id just do "ps -e | grep nvidia-persistenced"
