I have added module nvidia to /etc/modules to ensure it will be loaded at boot time;
cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
nvidia
and then update initramfs with "update-initramfs -uk all".
