i get the following:

$ primusrun glxgears
primus: fatal: Bumblebee daemon reported: error: [XORG] (EE)

$ optirun glxgears
[23162.070642] [ERROR]Cannot access secondary GPU - error: [XORG] (EE)

ive tried various basic amendments such as

adding my user to the bumblebee group;

manually specifying the nvidia option in /etc/bumblebee/bumblebee.conf;

manually specifying BusID "PCI:1:0:0" in /etc/bumblebee/xorg.conf.nvidia
(from the github FAQ)

$ lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core
processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce
610M] (rev a1)

i admit im stuck
