module 'nvidia' is not found

I also read this answer.

Any ideas?

Answer 1

The problem is secure boot, it didn't allow bumblebee to install nvidia.

• Try to uninstall bumblebee

  sudo apt-get install ppa-purge sudo ppa-purge ppa:bumblebee/stable sudo apt-get purge bumblebee

• Turn of secure boot from your bios setting

• Install bumblebee agian and it will work properly
