bumblebee fails to work in Ubuntu 18.04 with nvidia-driver-390 unless these configuration changes are made:

1. For optirun to work, /etc/bumblebee/bumblebee.conf needs two library paths changed (because of the changes for GLVND):

[driver-nvidia]
LibraryPath=/usr/lib/x86_64-linux-gnu:/usr/lib/i386-linux-gnu
XorgModulePath=/usr/lib/x86_64-linux-gnu/nvidia/xorg,/usr/lib/xorg/modules,/usr/lib/xorg/modules/input

With these changes, optirun works correctly on my laptop (using rhe primus bridge) but primusrun still fails.

2. For power management to work (ie turning the nvidia card off whilst not in use), the nouveau and nvidia modules need blacklisting so they don't load on boot, and nvidia_drm and nvidia_modeset need aliasing to off so they never load. Otherwise, nvidia_drm attaches to drm_kms_helper and then bumblebee can't unload the nvidia module and turn off the card. This configuration file in /etc/modprobe.d/nvidia-bl.conf works for me:

blacklist nouveau
blacklist nvidia
blacklist nvidia_drm
blacklist nvidia_modeset
alias nouveau off
alias nvidia_drm off
alias nvidia_modeset off

(The first two lines are already in bumblebee.conf. I found I also had to alias nouveau to off because gdm?/mutter? so desperately wants to load it.)
