I need to run CUDA enabled applications, but (because of other things) I'd rather use Optimus technology rather than running on Nvidia card only. Note that for CUDA I need to use proprietary binary nvidia drivers.

I followed: https://wiki.debian.org/Bumblebee this tutorial (and setup is mostly working). After reboot I can successfully run optirun something command. But after some time I get:

 optirun deviceQuery 
 [ 4574.136296] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card
 [ 4574.136358] [ERROR]Aborting because fallback start is disabled.

I use Quadro K2000M:

  lspci -k 
  01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K2000M] (rev ff)
  Kernel driver in use: nvidia

Here are my questions:

  • Does anyone have pointers how to solve this problem on debian.
  • Is there any guide on manually restarting nvidia card using bbswitch?
  • How can I disable bbswitch at all (losing power management)

Could anyone create proper tags:

  • bumblebee, cuda, optimus
