It seems that nvidia-prime bring a solution for this bbswitch issue:
"- Make sure that NVIDIA is always enabled on shutdown.
This will avoid issues with the BIOS." -- changelog of version 0.5
So, is it better to change the package affected to bumblebee? It should
install /etc/init/bbswitch.conf, like comment #3.
(see Bug #1268217, there is a problem about bumblebee and nvidia-prime,
the 2 packages must conflict, but they don't)
** Package changed: bbswitch (Ubuntu) => bumblebee (Ubuntu)

Title:
bbswitch-dkms causes forced shutdown (even in reboot)
Status in “bumblebee” package in Ubuntu:
New
Bug description:
I instaled bumblebee-nvidia for Optimus support in my Asus laptop and
bbswitch-dkms causes forced shutdown, even if I reboot system. My HDD
makes a loud noise, It is as if the power went out, the forced
shutdown is very violent (there is not plymouth shutdown screen). I
know that bbswitch is used for turn on and turn off nvidia card, but
somehow it is affecting shutdown/reboot.
Steps to reproduce:
- Install nvidia-319-updates (319.49) and bumblebee-nvidia (in trusty,
nvidia-331-updates and bumblebee package);
- Configure bumblebee files to works with nvidia module;
- Reboot system, bbswitch will be active in the next login;
- After login system, try to turn off the system, or reboot. System will
causes a forced shutdown (it seems it can be reproduced if you use nvidia card
in the session);
There is workaround to avoid this problem, runs:
sudo modprobe -r bbswitch
before every shutdown or reboot.
Or add the next initscript (/etc/init/bbswitch.conf) :
description "Save power by disabling nvidia on Optimus"
author "Lekensteyn <[email protected]>"
start on runlevel [2345]
stop on runlevel [016]
pre-start exec /sbin/modprobe bbswitch load_state=0 unload_state=1
pre-stop exec /sbin/rmmod bbswitch

Please, this is a important (and dangerous) bug, anyone that tries to
get Optimus tecnology works in Ubuntu and uses Bumblebee probably will
get a HDD broken in a few months of use, without knowing why.
