Dear Maintainer,
* What led up to the situation?
Installed nvidia-kernel-dkms 352 from jessie-backports.
* What exactly did you do (or not do) that was effective (or
ineffective)?
After installation, rebooted and found that after running
optirun for the first time, /proc/acpi/bbswitch would still
report ON after optirun had finished.
Stopping the bumblebeed service and "rmmod nvidia" then running
bumblebeed -vv showed everything was normal during start up,
however upon quitting optirun the log shows:
[ 341.192631] [DEBUG]Socket closed.

Closing log file.
The "nvidia" kernel module remained loaded and bbswitch was
unable to switch the nvidia card to OFF. Running "modprobe -r
nvidia" manually brought up the same error, instead I had to
run either:
modprobe -r nvidia-current
or
rmmod nvidia
If I create a sym link from nvidia-current.ko to nvidia.ko and
from nvidia-current-uvm.ko to nvidia-uvm.ko then run depmod -a
everything then works as expected.
/etc/nvidia/nvidia-modprobe.conf contains what looks to be
suitable aliases to allow modprobe -r nvidia to unload
nvidia-current however I'm not sure if that file is loaded or
how to check.
Either way, it looks like bumblebee is unable to unload the
nvidia module that was loaded via nvidia-current and in turn
that is causing bbswitch to be unable to disable the dedicated
graphics card.
