I have Debian Sid on my XPS 15 9560, the system informations are like
follows:

```
Debian GNU/Linux buster/sid \n \l

baseboard-product-name: 05FFDN
baseboard-version     : A00
system-manufacturer   : Dell Inc.
system-product-name   : XPS 15 9560

bios-version          : 1.3.4
bios-release-date     : 06/08/2017

optirun (Bumblebee) 3.2.1
```

I have installed the `bumblebee-nvidia` package from the official
repository. But when I use `optirun`, the terminal outputs following
error:

```
$ optirun -vv glxgears

```

Then I tried to configure the `KernelDrive` in
`/etc/bumblebee/bumblebee.conf`, neither `nvidia` or `nvidia-current`
works.

When I run `sudo modprobe nvidia-current`, the error is like this:
```
$ sudo modprobe -vv nvidia-current
modprobe: INFO: ../libkmod/libkmod.c:364 kmod_set_log_fn() custom logging 
function 0x9820ee7390 registered

modprobe: INFO: ../libkmod/libkmod-module.c:886 kmod_module_insert_module()

'/lib/modules/4.11.0-2-amd64/updates/dkms/nvidia-current.ko': No such device
modprobe: ERROR: could not insert 'nvidia_current': No such device
modprobe: INFO: ../libkmod/libkmod.c:331 kmod_unref() context 0x982129d200 
released
```

I have checked the `modules` directory, it contains all `nvidia-
current.ko` and `nvidia-current-drm.ko` etc files.

I remember that when Debian was using kernel `linux-image-4.9.0-3-amd64`
there weren't any problem, however when it automatically upgrades to
`4.11.0-1-amd64` and `4.11.0-2-amd64` then bumblebee produces the error
above.

Attached please find the report generated by `bumblebee-bugreport`.
