nvidia-367 broken by upgrade to .57

[Peter Silva]

laptop with intel and Nvidia GT 860M was working fine with primusrun to run Steam games. After automated update to -367.57, it is entirely broken. when I run primusrun <anything> the screen mode is changed to an unusable one (screens become mirrored, making content on the lower screen inaccessible.) and it does segmentation fault, core dumped.

I have coredumps, but they say they are uploaded. Don´t know how to find some sort of reference in apport.

I fixed it with:

sudo apt-get install --reinstall bumblebee bumblebee-nvidia

reboot.

no idea what that did.

Status changed to 'Confirmed' because the bug affects multiple users.

`sudo apt-get install --reinstall bumblebee bumblebee-nvidia` didn't work for me. When I try to my prime on NVIDIA performance mode it goes back to intel power save mode on logout/login.

Why in the world is every earlier version dependent upon the 367 version? So I can't go back to a working driver? Asinine.
