Hi static, first, thanks for taking me further along the road to installing my cuda drivers than I had thought possible, outstanding instructions. Like the fellow above me, when I run "optirun glxinfo | grep -i "direct rendering"", I get the following:

[ 205.729643] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) NVIDIA(GPU-0): Failed to initialize the NVIDIA GPU at PCI:1:0:0. Please

[ 205.729694] [ERROR]Aborting because fallback start is disabled.

Dual boot win7/ kali 1.08 AMD64, lenovo w530

Bumblebee isn't starting for whatever reason. Any thoughts? Thanks.
