For brevity, I'll focus this post on the command:
optirun glxspheres64I am noticing other effects that are illustrated by that command's behaviour. I have been slow to notice the problem but I have determined that it occurred a couple of updates ago for:
nvidia, nvidia-utils, opencl-nvidia
The last working set was: nvidia-367.27-1-x86_64 opencl-nvidia-367.27-1-x86_64 nvidia-utils-367.27-1-x86_64 (linux-4.6.3-1-x86_64) Reverting resolves the issue.
I have retroactively discovered that it broke as of:
nvidia-367.35-1-x86_64 opencl-nvidia-367.35-1-x86_64nvidia-utils-367.35-1-x86_64
Syu does not fix it.
The problem (finally)
Newer sets return only the following terminal output:
$ optirun glxspheres64
Polygons in scene: 62464 (61 spheres * 1024 polys/spheres)
$ No graphic is displayed. That's no graphic, not a black graphic. optirun glxgears also terminates without a graphic. Running without optirun produces the expected result.
Here's a verbose output:
$ optirun -vv glxgears

I assume I have missed something stupid but I have verified the the wiki process and found that only package reversion fixes it for me.

You are not the only one. I noticed that with those drivers i cant open nvidia-settings with 'optirun -b none nvidia -settings -c :8', but it works just fine with 367.27 and earlier. So i downgraded to 364.19 [i am having different problems with nvidia-367.27, some memory/reclocking issues on my GT 650M]

Fixed today with nvidia 370.23-1 and opencl-nvidia 370.23-1
