bumblebeed itself fails in the modprobe call, so reassigning back for
now. This could also belong to kmod, but let's find out what's wrong
first. What does that command say?

   grep -r off /etc/mod*

My suspicion is that there is some "alias whatever off" in
/etc/modprobe.d which bumblebee tries to load, and bumblebee calls
"modprobe whatever" and gets this error:

modprobe: ERROR: ../libkmod/libkmod-module.c:816 kmod_module_insert_module() could not find module by name='off'
modprobe: ERROR: could not insert 'off': Function not implemented

This is how current kmod behaves, and is independent of systemd vs.
upstart. That may or may not be a kmod bug, but I don't think it is --
"off" is not a magic name in any way, it's not documented in man
modprobe.d. So it seems "off" is merely a convention, but modprobing
indeed will fail. I'll wait for your confirmation, then we can set this
to "Triaged", and I suggest the upstream bug should be reopened.

Thanks!
I don't see any "off" in the bumblebee source, and debian/bumblebee.conf (which gets installed into /etc/modprobe.d/bumblebee.conf) looks fine to me.

** Package changed: systemd (Ubuntu) => bumblebee (Ubuntu)

** Changed in: bumblebee (Ubuntu)
       Status: New => Incomplete

** Summary changed:

- bumblebee doesn't work with systemd on 15.04, but works with upstart
+ bumblebee fails on trying to modprobe "off"

Title:
  bumblebee fails on trying to modprobe "off"

Status in bumblebee package in Ubuntu:
  Incomplete

Bug description:
  Currently Ubuntu switched to systemd by default, unfortunately bumblebee is not working in this case.
  I have proprietary nvidia driver and bumblebee from standard repository, kernel 3.19.0.

  When booted with upstart - works perfectly

  From bumblebee developer:

  > Looks like a compatibility issue with the modprobe configuration file on Ubuntu.
  > When I said compatibility, I think that systemd(/kmod?) does not like the alias nvidia off line in some modprobe configuration as supplied by the nvidia package.
