I recently upgraded to 15.04 and after successful installation I noticed that Bumblebee has stopped working. Optirun/primus commands do not detect the gpu anymore (640M LE). Here's what I get when trying to run Steam:

$ primusrun steam
Running Steam on ubuntu 15.04 64-bit
STEAM_RUNTIME is enabled automatically
Installing breakpad exception handler for appid(steam)/version(1428965940)
primus: fatal: Bumblebee daemon reported: error: Could not load GPU driver

You are in the 'publicbeta' client beta.

My driver is nvidia-346-updates.

Configuration files are default. Should I change my kernel driver and library path? (Right now they are nvidia-current).

I got it working like that on Kubuntu 15.04 with 340.76:

Driver=nvidia
...
[driver-nvidia]
KernelDriver=nvidia_340
PMMethod=auto
LibraryPath=/usr/lib/nvidia-340:/usr/lib32/nvidia-340:
XorgModulePath=/usr/lib/nvidia-340/xorg,/usr/lib/xorg/modules
XorgConfFile=/etc/bumblebee/xorg.conf.nvidia

What does "optirun --verbose glxgears" return ?

Edit : I had to change KernelDriver to fit the proper name of the module (I use nvidia-349 so I had to put nvidia-349 instead of nvidia).
Once I dit it, I had to update the XorgModulePath to fit the proper paths to the libraries according to the version of your driver. For me it is :

/usr/lib/nvidia-349/xorg,/usr/lib/xorg/modules

PS : Thanks to A.B. for his comment

I had the same problem.

I solved changing some lines in file /etc/bumblebee/bumblebee.conf: (I my case I'm using the version 352 of nvidia driver, change this value by your driver version)

KernelDriver=nvidia-current
LibraryPath=/usr/lib/nvidia-current:/usr/lib32/nvidia-current
XorgModulePath=/usr/lib/nvidia-current/xorg,/usr/lib/xorg/modules

to

KernelDriver=nvidia-352
LibraryPath=/usr/lib/nvidia-352:/usr/lib32/nvidia-352
XorgModulePath=/usr/lib/nvidia-352/xorg,/usr/lib/xorg/modules

You can restart the bumblebee service with:

sudo systemctl restart bumblebeed.service

To check the service status:

sudo systemctl status bumblebeed.service

and you can check the log in /var/log/syslog file for any error.
