Can't login after install Nvidia Driver in Driver Manager

[Jazzcat]

I'm a bit stuck on this one, I've tried every iteration I can think of for the below command and I can't get vlc to work with it.

vblank_mode=0 VLC_VERBOSE=3 optirun -b primus  vlc -info

It works without bumblebee if I just run

vlc

primusrun gives me a segfault

it seem that /etc/modprobe.d/bumblebee.conf is missing

After trying and failing a building from source, I reinstalled nvidia-349 bumblebee bumblebee-nvidia primus and added the appropriate entries to blacklist. sddm is now all good but vlc still won't work. I've just been using parole. Everything else seems fine.
