I tried this today as well but no success..
system got awfully unresponsive etc
then I reinstalled bumblebee from here:
which also installs the older nvidia drivers 259.53
after that my system became a real mess but
I got my screen back
bumblebee service seems to load fine but
when I try: optirun glxgears
I get the following:
"Cannot access secondary GPU - error: You need to change the ConnectedMonitor
setting in /etc/X11/xorg.bumblebee.conf .."
I tried different parameters from ConnectedMonitor such as "DFP-0", "CRT-0" etc
but no success
then I also checked:
the output was:
Number of GPUs: 1
Name : GeForce GT 650M
PCI BusID : PCI:1:0:0
Number of Display Devices: 0
so there is indeed no monitor wired to Nvidia's card.
so.. go to hell bumblebee!!
I'd rather use cygwin for CUDA programming..
