Hi all,
I have a problem with installing Bumblebee to my Lenovo Y510P laptop (3GPUs 1 integrated intel and 2 Nvidia GeForce GT750Ms). I have Kali 1.0.8 installed on HDD dual boot with Windows 8.
I followed this thread/guide

but I got stuck at two stages:
  1. When I had to restart Bumblebee (/etc/init.d/bumblebeed restart)
  2. I removed (physically) my secondary GPU and I successfully restarted Bumblebee but after I got stuck again when I had to run "optirun glxspheres64"

In the 1st case the output was the following:
Code:
root@kali:~# /etc/init.d/bumblebeed restart
[....] Restarting bumblebeed: bumblebeedERROR: could not insert 'bbswitch': No such device
. ok
In the 2nd case the output was the following:
Code:
root@kali:~# optirun glxspheres64
[  171.908984] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.

[  171.909044] [ERROR]Aborting because fallback start is disabled.
And also I have a strange lspci | egrep 'VGA|3D' output (no device name):
Code:
root@kali:~# lspci | egrep 'VGA|3D'
01:00.0 VGA compatible controller: NVIDIA Corporation Device 0fe4 (rev a1)
07:00.0 3D controller: NVIDIA Corporation Device 0fe4 (rev a1)
I can't adjust the resolution of my screen neither, in the Display settings it says: Unknown device and I cannot set it higher than 1024X768. Basically I cannot do anything which requires display driver.

Any help is greatly appreciated, I have searched the whole internet and nothing helped.
