I installed ubuntu 13.10 and followed the instructions on how to install bumblebee.

I then did a test with glxears and the optirun glxears but I get the same frame rate. My guess is optirun wont switch to nvidia, previously if I ran optirun cairo-dock I would get the dock with full effects now I don't get it

It worked fine in ubuntu 12.04

Also when running nvidia-settings I get the following error :

You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server

Is there also a way to tell what nvidia drivers I have installed ?

And how do I get optirun to switch from on-board to Nvidia ?

I have a PC with :

Nvidia 640m le

ubuntu 13.10 64bits
