As you can read on bumblebee FAQ, you have to run nvidia-settings via:
optirun nvidia-settings -c :8
And then it will work.

Also for vdpau you have to prefix the driver as an env variable, sorry but
I forgot what it is exactly, but you can easily search for it. And then
again it's completely overkill, it will just eat your battery for no
benefit, the Intel cards can manage video just fine these days.

I would very, very strongly recommend against installing Ubuntu packages in
Debian. Our drivers system is packaged in a very different way and comes
with extra packages, and its very likely mixing and matching will horribly
break at some point down the line. Especially moving .so around manually
will mean you have to manually maintain it every time there is an update.
Please realize that is completely unsupported so when things break we won't
be able to help.

The recommended setup on optimus systems is to use bumblebee, so that your
desktop uses the low power integrated Intel card that doesn't kill your
battery in 15 minutes and is more than adequate for normal usage, and then
do heavy workloads like games or opencl through optirun when you need the
performance.

Kind regards,
