Boa madrugada linuxers! Estou com problemas para ver o bumblebee funcionando no Fedora 24 com ambiente Gnome 3.20 e arq 64 bits. Tenho uma nvidia 940m que usa a tecnologia optimus.
Segui os procedimentos do

https://fedoraproject.org/wiki/Bumblebee 

corretamente, porém na hora de executar o comando bumblebee-nvidia --check, aparece o seguinte erro:

--force compile selected via /etc/sysconfig/nvidia/compile-nvidia-driver
Warning! This NVIDIA driver has not compiled successfully before on kernel 4.5.7-300.fc24.x86_64!
Warning! This NVIDIA driver userland
/usr/lib64/nvidia-bumblebee/libGL.so.1 library is missing!


Warning! nvidia.ko was not created in in the kernel tree!
modinfo output for NVIDIA:

modinfo: ERROR: Module nvidia not found.

Check bbswitch kernel module...

Warning! bbswitch is not loaded into this kernel!
Since bbswitch is not loaded into the kernel, lets do additional checks on it...
dkms status bbswitch output:
bbswitch, 0.8.0, 4.5.7-300.fc24.x86_64, x86_64: installed

if the bbswitch package is installed, you may wish to try:
/usr/sbin/dkms add -m bbswitch -v 0.8.0
/usr/sbin/dkms build -m bbswitch -v 0.8.0
/usr/sbin/dkms install -m bbswitch -v 0.8.0
/sbin/modprobe bbswitch

To get clues as to why bbswitch is failing on this kernel...
All NVIDIA checks completed, but there were 1 or more failures...
Try running this script with the --debug option to find clues about what has
gone wrong with the NVIDIA driver compile process.


E depois de realizar o bumblebee-nvidia --debug aparece este erro:

--force compile selected via /etc/sysconfig/nvidia/compile-nvidia-driver
--debug mode selected.

ERROR: The kernel module failed to load, because it was not signed by a key
that is trusted by the kernel. Please try installing the driver again,
and sign the kernel module when prompted to do so.


ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that differs
from the one used to build the target kernel, or if a driver such as
rivafb, nvidiafb, or nouveau is present and prevents the NVIDIA kernel
module from obtaining ownership of the NVIDIA graphics device(s), or no
NVIDIA GPU installed in this system is supported by this NVIDIA Linux
graphics driver release.

Please see the log entries 'Kernel module load error' and 'Kernel
messages' at the end of the file '/var/log/nvidia-installer.log' for
more information.


ERROR: Installation has failed. Please see the file
'/var/log/nvidia-installer.log' for details. You may find suggestions
on fixing installation problems in the README available on the Linux
driver download page at www.nvidia.com.
